- Sound deadening your vehicle can be made cheap and easy with a small amount of soundproofing material on the right spots! I have a before and after sound test where I added some sound deadening material from Canopus inside the wheel well to see if it makes enough of a difference to make it worth it!

There's another gadget that makes your car quieter as well. It fits right over her mouth. 😆
Putting it in the doors helps alot. I find it funny that people ask if the extra weight effects the mileage. Yet 70% of people in the U.S. are over weight more then this sound deadener. lol
And also speed to get nowhere.
-and drive around in big empty pick-up trucks or SUV's... @@onlyrog5
ya, I guess losing weight of people onboard is easier to get less weight, lol
Haha, good point!
🤣
Great video, but Jesus Christ man, use jack stands when working under a vehicle! Never trust the jack alone!
Yes! Great point! Thanks
@@soundproofguidefor real man. What a bell-end.
What I came to the comments for. The floor jack doesn’t make enough difference from the stock jack
Must you curse the Lord? Have some respect and turn your filter on!
@@wurly164my friend passed away when his car fell on him. It's not a Karen comment. It comes from a place of concern.
20mm foam or fleece in a very thin polyethylene film (plastic bag material) will be most beneficial, applied to rear surface of wheel arch liner. 20mm is minimum for absorbing tire tread peak frequencies which are usually around 800-1200Hz, but can only be used if there is room for it, as you don’t want to push liner into wheel travel envelope. Also road noise best measured only up to around 30mph, above that wind noise starts to become predominant. Plastic film is to stop the absorber
becoming filled with dirt when wet, reducing absorption.
Sound deadener or damper pads are best applied to the body in flat areas. I did vehicle NVH for many years in a previous life. Hope this helps.
Thanks!! Yes it helps a lot! 😊
Good info, but I think it’s debatable where wind noise takes over - probably very vehicle dependent.
@@ScottoGrotto Yes you could definitely be right. As I said at the nd of the video, you might not see much difference with a luxury car but with a cheaper compact car, you'll have a better chance in being happy with your time and effort in installing this stuff. It's not expensive, just time consuming. Thanks for the feedback 😊
Would it be worth doing that to my 2011 BMW 328i, or does it probably have sufficient sound damping on the wheel wells?
Also would it help to reduce cabin noise by putting a thin layer of butyl under the floor mats ?
Thank you
@@Nightjar726 i don't think anyone has a catalog of cars stating whether they have insulation or not in certain spots. you'll have to pick up a screw driver and find out.
Keep in mind the logarithmic scale of the decibel measuremnent system.
A noise reduction of "only" 3 decibel is equivalent to a reduction of 50% of the sound intensity.
A noise reduction of "only" 2 decibels in your case is equivalent to approximately 33% reduction of the noise intensity. It's like having 2 radios broadcasting white noise instead of 3.
So really it makes a nice difference, and for only a couple of dollars too, it sure makes it worth it
This is Bingo Correct.
THANKS! I NEEDED CONTEXT CUZ I HAD NO IDEA IF THIS WAS NEGLIGIBLE AMOUNT! (not sarcasm, btw).
@@jpadamada It must be noisy in your car if your are SHOUTING !
I have successfully removed a LOT of drone noise and NVH (noise, vibration and harshness) from my car after doing four things that made a big difference. (And I had like everyone else started off by trying to get things quiet using butyl mats/dynamat etc. I realised that that had a very limited effect and beginners usually end up sticking down way too much of the stuff and later regret it because you start thinking how much you’ve weighed the car down by. And a year or three down the line you end up taking two thirds of it back out - or trying to). Here in England I run a 2011 Ford Mondeo (Fusion) estate/station wagon. MY FOUR BIG TIPS for INSTANTLY reducing noise (REMEMBER - you are NOT going to get your sub-$25thousand dollar car to hush like a Bentley. BUT - you can get a LONG way towards it.) NUMBER ONE - REPLACE YOUR TYRES. If you want quiet, you need to LIFT the car further away from the ground and have less tyre in contact with the ground. So run NARROWER tyres with a TALLER SIDE WALL and if you can a SMALLER RIM SIZE. I replaced my 215 55 R17 tyres with 205 65 R16 tyres on replaced 16 inch rims. This dramatically reduced the rolling drone of the tyres on the road and gave a softer ride because the taller side wall raised the car further above the ground as well as reducing the contact with the ground. Yes you will get less of a sporty ride but I’m not interested in a sporty ride. NUMBER TWO - INSERT SURGICAL TUBING into all your door seals. You need to improve resistance to outside sounds coming in. Adding surgical tubing into all your door seals makes them nice and snug. Don’t go TOO tight though - get the right tube width - or else you won’t be able to shut the doors and you’ll feel real dumb. NUMBER THREE - Buy cheap ‘RECON FOAM’ cut it up into small cubes and shove it compacted in all the empty cavities under the trim around the console, footwells and glove compartment. You wouldn’t believe how many just open holes there are in that area doing nothing but causing sound from the engine and up from the ground to reverberate around. Foam (NEVER USE SPRAY FOAM - it will enter places you really don’t want it to get and you will never get it out in the event of a repair requirement) dampens all that NVH and contributes to the multi-pronged solution we are going for. You need to do a LOT of things to add up to removing those decibels. NUMBER FOUR - Go to the back of the car. On most cars under the rear bumper on the left or right corner area hidden away you will find a one-way ventilation flap on each side of the car. These are interior pressure flaps that allow air to escape from the car when the doors are closed and to allow ‘used’ air to escape from the cabin as new air enters from the front air vents. BUT they usually are located behind a very large cavity that sits adjacent to the rear wheel arches. In some cars you can reach into this large empty cavity through the back hole at the rear of the small felt door/closet you find in the left or right wall of the boot/trunk - the little hidden hole you might put an emergency traffic cone of yellow jacket in for example. I discovered one of these cavities causes a LOT of droning noise. The noise from the rear wheel comes straight through them, reverberates and comes out through the rear air escape vent. FILL THAT CAVITY UP! DOn’t fill both - you need one to maintain the ability to release the cabin air pressure remember - and often the fuel fill area prevents access to one of the cavities depending on if you have a left or right hand drive. But if you can get access to one side - fill it up tight with old rags, recon foam, old pcarpet that can be scrunched up - you want as much as possible to remove cavity space that creates reverb. Use anything not too heavy but DENSE. So recon foam, being more dense, is a lot better at dampening and muffling drone that say bubble wrap. Pack it in tight - and there’s room for a lot of foam and rags in there. This for me REMOVED 80% of the heavy drone in the back of the car - particularly on long highway journeys. NUMBER FOUR POINT ONE (!) Not essential but this improved my car dramatically - If your car is one of those that tilts down slightly towards the front end (to allow for the backend to dip slightly and the car to even out when the trunk is fully loaded) buy a pair of polyurethane lifting spacers to sit at the top of your front struts. Your garage can fit them for about $250. They again move the from end higher off the ground, away from the noise of the road. So coupled with the tyres we’re really changing how close we are to the noise of the road. Plus they make the car sit more evenly and look a lot better. These are my main tips for really getting to a quieter, pleasant drive. And they have really worked for me. I wish you all the best with your own particular car - every one has its quirks and every one will have slightly different solutions. But persevere and you can get a nice result.
Nice
That was a great reply with better ideas than the video. Thanks a lot!
Thanks (Some paragraph spacing would be really helpful.)
You can blow out window seals if you cover the air dump shutter.
Nice
I'm a Honda technician, I drove a car that was missing the wheel well guard once, and couldn't believe how loud the road noise was! That's what gave me the idea to insulate the wheel well liner. Also, anyone who has worked on a honda knows how thin their wheel well liners are.
Agreed!
You should see how crappy the liners are on other cars if you think Hondas are thin.
Great, do you think its better to apply on the liner or the metal arch area above the liner.
@@aakudev depends on how long do you want the liner to last.
I have a 2012 accord . And factory has installed a very very small patch of sound deadening to the rear wheel wells
Another way to reduce noise: Make sure your tires are good and balanced. My tires are nearly worn out and I always notice how much quiter and smoother it is with new freshly balanced tires.
Very true! Also the type of tires will make a big difference! Thanks!
Tyres have a number of variables to manage that will influence Noise, Vibration.
1. Tread pattern and wear - noise magnitude and specific resonant frequencies for certain speeds - some are renowned for horrible noise.
2. Balance and air pressure - suspension bounce, and how well the tyre mates to the road dramatically impact vibration and thus introduced noise.
3. Tyre wall height. Lower profile = louder due to higher rigidity.
4. Tyre width. More tyre on the ground = more noise
5. Tyre compound. The hardness will alter the level of sound
When shopping to replace your tyres it is REALLY helpful to investigate the quietest tyres for your vehicle that also still meet your driving needs and expectations for climate, life of tyre etc.
Final tip, ask/investigate tyres different to your stock dimensions but still compatible (eg wider/narrower) because the more common a tyre is the cheaper it usually is. EG my car tyre costs $450 but if I buy the one 1.252cm wider it is for the most common vehicle in my country and only $200 for the same model.... economies of scale and competition at work :).
That’s a significant reduction in decibels for one area of treatment!
Quieter tires of course help here too.
I switched to Michelin pilot 4 A/S, and my 2002 WRX Wagon became a lot friendlier on noise!
I did the whole back of the car treatment up to the front seats to quiet the interior from my aftermarket axle back muffler :)
I’ve been meaning to get around to the front of the interior for awhile…
Looks like a good product you found.
I used a butyl damping layer with closed cell foam adhered to the top.
Layered up the butyl till it passed the rap test in an area. Then applied the foam layer.
Thanks for sharing your experiences, cool videos!
The human ear can just about perceive a 1dB change, so 2dB is going to be pretty insignificant. Certainly not worth going to all that trouble for 2dB. Changing the tyres to a quieter tyre will have more of an effect on Road/Tyre noise, all be it a more expensive solution.
@@grahamtricker4103 Whether or not it's worth reducing the noise level 2 DB is going to be dependent on the person. You may not think it's worth it, but I do.
how can you even start to compare what you did with $20 noise reduction? Are you well? Maybe you can just buy a Mercedes instead of a set of tires?
@@Ludak021Scotto didn't say anything related to a $20 noise reduction. I think you're a little mixed up. He simply sharing his experience in reducing noise for his vehicle.
I had a 2008 A3 Hatchback that I could always hear tire noise. I installed a waterproof sound deadener on the "cabin side" inside of the front fender liners. Made a noticeable difference. I was worried about trapping water (and causing rust) so I did not install on the metal body.
Thanks for taking this on! I am a SQ sound listener and have done my whole car except for the wheel wells and the 20 Camry with the Panoramic sunroof. I will do the wells to add that extra from these noisy Mississippi roads! Semper Fi and Can Do
Are the panoramic roof models a lot nosier as standard?
@@philtucker1224 very noisy with blind open and some damping with it closed!
@@TushkaLusa_AL ok yes, my last one (Peugeot) was the fixed type, non opening..
One safety tip: If you don't want to use or invest in proper lift stands, you can slide them under the frame (close to jack) as a safety measure. If the car falls off the jack, or the jack fails, it will fall onto the inflated tire or rim before crushing you. You might end up with a ruined tire or damaged wheel, but you should be fine. Plus, as the tire is rather wide, it will allow for a sideways slip (to some extent), not just up and down. As I have lift stands, this is something I always do when changing a tire roadside.
Stands are a must, a friend was killed when his jack failed. Hydraulic jacks are actually more dangerous than the the OEM jack as a hydraulic failure will cause it to collapse instantly. And the tire under the car is something I always do, even with stands......
This is amazing. I bought a spray on type for my vehicle, but it works well. I spray all the inner wheel fenders like you, however I took it one step further and inside the vehicle, I took out the interior plastics and trims and sprayed all the bare metals and wheel fender bump that you see inside most suv's in the trunk area ( I have a 4runner). Suv's generally produces the most road noise from that area of the trunk and I spray every part of it and the noise is NOTICEABLY gone now. This is the coolest hack ever to achieving a quieter vehicle !!!
whats the spray called
@@ryansaly7539 DEI boom mat. I got it from Amazon.
If you use this stuff try putting it in places that are flexible plastic stuff like door pockets, dash and center panel, door panels in the interior etc, you can hide it quite easily by tucking it under or in these areas, makes a big difference and it doesnt take much to dampen the sound a bit. A problem with putting this in the wheel wells is these areas need dissasembly to maintain the car for instance some lights and evap equipment requires the liners be removed to replace bulbs or parts. if you can avoid covering up the fasteners its ok.
i was just looking for a before and after! i’m committed to this now lol
Great video and good point about the jack except that you are trusting your life to hydraulic seals ! It was drilled into me as a young lad never trust your life to hydraulic pressure only . I would recommend the addition of some sort of jack stand as the safest, most stable support .
If you have a spare tire, lay it flat under the area next your work space. A little added precaution.
You could spray rubberized undercoating on the side of the fender well liner where you put the sound deadening material. Quick, easy, cheap.
Yeah, helps keep the rust in
Best wheel roller / sticher that is FREE!
Used timing belt tentioner with attached pulley. Use tentioner as handle. No one at my shop could ever thought of that. Blew their minds.
That was a significant change. Thank you.
Try noice cancellin with amplifier.
Mic or speaker (as a mic) connected to car floor (cone pointing floor) and conneted to amplifier. Subwoofer and speakers from that with opposite phase and you can adjust volume with speaker level adjustment and adding more or less mass to mic
cone.
Great video! I can recommend wearing light weight gloves doing this work because the cut aluminum edges can put micro cuts on your finger tips .
Hi
I was wondering if you had any advice for sound proofing a door with glass panels. I just moved into a new flat with my friend where all the doors including the bedroom doors have glass panels as well as lots of gaps and you can hear everything! We are both students and dont have a lot of money to spend but would love to give ourselves more privacy if you have any ideas. I am just worried sealing the gaps around the door, spending lots on that and it not doing much because of the glass panels. Anyway thanks and great channel!!!
Try taping bubble wrap to the glass panels. We've done this on our laundry door, primarily for insulation purposes but it also reduces noise transmission.
Thanks for the tips. It is an easy modification to make. I tried this on two of my cars and it made a noticeable difference. I used some Noico sound deadener mats on the rear portion of the plastic fender liner and used spray on sound deadener on the front portion. (Reverse for the rear wheel wells) for a 2db reduction . It was a great start. I may purchase another Noico kit and try some other areas. The main reason I used so little on the liners was that I only had a few pieces left of a small 10 sq ft kit, and the rest was used on both hoods. Seeing the proof, I wish I purchased a larger kit to continue in the cabins.
Thanks for sharing! For the little money and a couple of hours of your time, it’s definitely worth doing. I also find that it’s not only quieter but the tone of the noise is much more tolerable.
I think for the most acpustic treatment of wheel arch ppl use a 4-7 mm acoustic foam with that aluminium sheets. What you think?
I'm honestly not sure. Ill have to try that out someday! Thanks for the idea!!
Spray on sound deadening also works and would be easier to apply. Though it might be slightly more expensive.
Exactly 🙌🏻😊
Every 3 decibels drops the sound by 50% Good job
Did you perceive a difference in the tone of the noise aside from the magnitude?
Absorption material will enhance your result where you added the constrained layer damping material.
I'd expect less vibration and resonance from the material you added. A closed cell foam (hydrophobic) with adhesive backing applied through the wheel arch as fully as possible will make more difference in blocking the noise transmission - particularly with a mass loaded layer separated from the arch metal (dynaliner for example). This can be done from inside the vehicle and enhanced by layers under the external arch lining.
Yes I did. Especially when it rains. It still
Makes noise but it’s more deaden and less annoying.
a 0.2-0.3 db decrease is 50% less noise. thinking of doing this since i have some ceramic wool left over from another project and I like to over inflate my tires, i think it will help. maybe the only way to add weight as insulation and get better mpg as a result
My old tyres still looked good but made a loud drumming noise in motion. (My local garage boss said that make was now discontinued anyway) and the new set of budget tyres he recommended are so quiet now I could literally hear a clock tic ((if they still made them!)
Can you please do a video on how to sound proof a sliding door inside a home? Specifically for privacy, to prevent sound (primarily voices) from leaking out of a room?
Need more details. Is this a patio door? A sliding barn door? a pocket door? a closet door?
Rule #1 Any open crack allows sound transmission. If you cannot cover it, you cannot control it.
@@hjs9td it’s a sliding barn door that’s for a bedroom. Wondering what options there are to add around the edges of the barn door to help seal the spaces
@@mimigaudet7484 This will be very hard to do and you only see a modest improvement. Assuming that there is a track guide at the bottom of the door to prevent the door from pushing out at the bottom, you would need wiping seals mounted on the door jambs (the rubber comes in contact with the inside door face)and header to close the gaps there and a brush seal mounted on the inside of the door at the bottom. There will still be sound escaping at the bottom corners of the door.
You should now put some closed cell foam over the sound deadener. Also the Amazon basic sound deadener is also butyl based not asphalt. I used that plus some closed cell foam in the trunk. It made a big difference.
Good idea!
Always use Jack Stands, it doesn't matter how good your car jack is, everything is fine till it isn't!
Good video though, is this stuff available in Australia, please! Edit: it's available in AU.
I wonder if carefully spraying truck bed liner on the non-insulated spaces would work? It might be easier to do.
What about the spray kind? Is it good?
My wife's Honda Civic still uses these plastic wheel wells, my Toyota CHR on the other hand doesn't, I don't have any wheel wells, but metal is covered with some sort of epoxy like material which is hard.
You're very talented! Driving, holding cell phone/camera and holding the meter!!
I was also eating a burger but couldn’t see that in the clip.
@@soundproofguide😂
@@soundproofguide
And not wearing seatbelt 😅
need good tires that are balanced properly and make sure the suspension parts are in good condition as well.
Pro Tip! NEVER ride with your mother-in-law. Car will be blissfully quiet!
Amazon product actually has tested to be one of the best.
Do you have a roller you use to conform it to the substrate? A thick wood dowel with rounded end works well for edges, bends.
A roller does work better! I just couldn’t find it for the video.
High quality tires also make a huge difference. I put new tires on my car a little over a year ago and now when I'm cruising on the highway at 75mph all I hear is the sound of the wind rushing over the body.
Wouldn't some sort of spray on insulation be easier to just spray on and work as well?
If you're not using a jack stand, the jack that comes with your vehicle is going to be more stable and reliable than a hydraulic will. Hydraulic jacks are meant to put cars on jack stands. They are not meant to hold the car while you're working underneath.
Obviously, supporting a vehicle by any method requires that you have the wheels at the other end locked, like with the parking brake or with wheel chocks.
How does this mod compare to putting foam into the tires like ContiSilent?
Would have to reduce by 3-4 db to be worth it in my mind.
My concern would be how long the deadener stays attached in real weather conditions. Let us know if its falling off after 6 months or a year?
Unless those are made for outdoor purposes it’s useless 🙌🏻 nice vid bro
That's right: You need sound deadening material in your doors, on the car floor AND up under what used to be called, the firewall as well as the tyre wells. Some cars just use that underlay lightweight material inside.
If you're serious about it, I prefer taking the seats out, then take the carpet out. A lot of the noise is harmonics from the frame. Go to your local rubber supplier and get a few sheets of the 3mm (or 5mm- better) with sticky backing and apply to the whole floor area, the panel behind the back seat squab, and as far up the front firewall as you can manage. Then replace the carpet and seats. Result...amazing! It looks like a Vauxhall but it rides like a Jag.....nuff said....
Awesome!! Thanks!!!
1. ALWAYS wear a seatbelt 2. ALWAYS use jack stands or at least put your wheel underneath as hydraulic jacks can collapse instantly with no warning!
Mass loaded vinyl (MLV) products are best for keeping road noise out. Your making the metal panels less resonant.
Pro tip, buy a pack of those fragile plastic wheel well clips before you start this type project
You noticed that too? 😁 Yep. Imagine going through the effort to jack the car, remove the tire, breaking off a clip, then wondering how you'd get the well plastic firmly and safely back into place so you can use the car.
Rubberized undercoating can help too when applied properly.
Agreed!
@@soundproofguide If you remove the headliner, many mfr's just have a thin pad between that and the roof.
Even inside the doors there isn't much of anything to deaden sound.
They do this to cut weight and have less trouble reaching the CAFE Standards.
Don't they make a spray foam insulation? Just wondering
"use a sound spectrum analyser to better see if any frequencies of noise have disappeared instead of using a standard db sound meter" - this is what i read on other videos. not sure the validity of it. 😊
Better tyres perhaps?
I know exactly what you meant, and I would have said it too, so i promise this isn't a criticism or a negative comment or anything, but "let's see if we can hear a difference" is a really funny sentence😁😁😁
Haha Good point!
@@soundproofguide 😁
In the first Ghostbusters movie, when they're in the library, Dan Aykroyd says "Guys, listen, do you smell something?" So you're in extremely good company 😂
Also, meant to say this before, thanks for the video! It was entertaining and informative. Keep up the great work...
@craighambling That reminds me of my early days as radio announcer and news reader at a small station on Vancouver Island in the 80's. My mentor would listen to the tapes of my broadcasts to critique and assess my on air burbles. One day he said for me to drop the phrase, "Let's have a look at the weather" or "looking at the weather....". He pointed out it was Radio and not TV and we couldn't "look" at anything. I learned fast.
@@aloisius4188 😂😂😂 language is a funny, yet cruel, mistress!
Dosent it cause rusting ? Water splashes, accumulated on the material edges ?
That's the first thing I thought of, as trapped water WILL cause rust. Very bad idea. Better to take the interior out and place damping materials inside the car. Yes, it's far more labour intensive (ask me how I know) but definitely worth the effort.
@@Zgurkogel agreed. It is better to paste it inside. Remove quarter panel trim and paste it. But, i have done long back. It doesn't makes huge difference.
Someone else may have already schooled you on this. But a larger jack is not really the best practice, they can fail too, it happened to me once.
You should be using a jack stand
Good video, I had not considered putting it in the inner wheel guard.
I will be soon installing a full 3 stage sound deadening system in my 1981 Hilux 4wd that has a chev type v8, they are very minimal on factory deadening & the V8 does not help.
Well here's the thing. This is only gonna affect noise up until about 40mph and my 2024 Kia Soul is pretty quiet up until then and in fact isn't bad after that. The noise that starts to dominate above that speed though is wind. So I don't care what it is you're driving once you get above 70 mph things are gonna be noisier and especially on undivided roads when oncoming vehicles pass you. Another thing. If you have a dashcam that records audio its gonna pick up a LOT of road noise at any speed. And, BTW EVERY vehicle needs a dashcam.
Bet this really helps in the rain.
It sure does!!
That noise is the seat belt chime
Blessed are the deaf drivers and riders for they do not hear any noice except for the car’s vibration they feel.
The human ear can just about perceive a 1dB change, so 2dB is going to be pretty insignificant. Certainly not worth going to all that trouble for 2dB. Changing the tyres to a quieter tyre will have more of an effect on Road/Tyre noise, all be it a more expensive solution.
True. As to the video, it was encouraging, although -- to my way of thinking -- the dB reduction results may be specific to his vehicle. Yes. There are some commonalities from model to model when it comes to noise-entry locations, but for one particular model the doors might be a better area of focus rather than the wells, and so on.
It's enough to say that BMW e36 was 200kg lighter than e46 - in similar spec just because of the soundproofing mats.
Just spray some spray foam in doors, etc…hhahaha. El cheapo method. J/k. Great idea, thanks for the upload.
Anytime you work near or under a vehicle it should be on jack stands.
The majority of sound is the wind going over the car, you’d have to insulate the whole car in to reduce noise.
What happens when you stick that material inside the tyres? Will it reduce tyre noise?
If you do this, you will NEVER be able to properly balance those tyres.
@@aloisius4188 why? It's stuck to the inner tyre walls. Wheel balancing can be done after that.
Some tires actually come with foam stuck to the inside to reduce noise. Using soundproofing meant for metal won't really do anything but add weight, though, I think.
How come your car can run without the drivers seat belt engaged? Have you removed the safety relay?
Seat belts should not have any effect on the way the vehicle runs. If yours does, that then it might be your specific model of vehicle.
@@JasonWW2000 some countries limit the cars to 10mph
@@philtucker1224 There's your answer, different countries have different regulations. That's why his vehicle operates the way it does.
@@JasonWW2000 let’s hope he remembers!
Wouldn't that cause rust?
It will cause rust if there trapped moisture in between the material and metal. That’s why it’s important to make sure the surface is clean and dry.
Thick floor rugs.
To quote Soundproof guy “ a difference of one, or two decibels”.
Something to consider perhaps ? A skilled listener is supposed to be able to hear changes of 1dB or more. Less skilled listeners need more like 2 or 3 dB before they are sure there is a difference. (This is measuring source signal amplitude, by the way, not acoustic power.). Mind you there are other considerations here. If we hope it’s going to make a difference, are we more likely to think it does? Personally I’m not sure it’s worth the time and money……
It really depends on how serious you are about wanting to make your vehicle quieter.
@@JasonWW2000 I suppose it does. However, I suspect that most rate how ‘quiet’ a car is as an important aspect. Especially when choosing a new one, and they will take this into consideration, when watching reviews, and driving the cars in their ‘short’ list. I know I did.
For those who have unfortunately ended up with a car that they wish was quieter will, perhaps having watched this video, be tempted to try lessening the sounds by sticking sound deadening material in the wheel arches etc.
My observation was, that that the improvements might not be as effective as anticipated, if the facts I listed, are taken into consideration.
For some reason I just assumed that everybody watching this video is at a point where their vehicle has tire noise that is bothering them and they want to fix it.
I don't understand the comments where people say it's not worth it. Then why are you here watching the video? Lol.
I know people who spend hundreds and even thousands of dollars to make their vehicle quieter. I'm trying to keep my soundproofing budget under $1,000. The guy in the video is doing it super cheap and people are still saying it's not worth it. It cracks me up. 😂
@@Jestey6Also, keep in mind that the guy in the video is using a very basic SPL meter as opposed to an RTA which allows you to see all of the frequency range. He averaged a reduction of 2 dB, but we don't know at what frequency. At some frequencies there may be no change and at other frequencies there might be a big change. Maybe 3, 4 or even 5 dB. We don't really know because he isn't accurately measuring it.
Oh the seat belts!
Seatbelt on while driving please 😊😁
You should have soundproofed the whole car including under the boot trims, door trims, footwells, under the rear seats, the hood and boot door also.
I did all these from 20 sq metre of sound deadening stuff and now my vw golf sportline estate (sportwagon) is quiet as our Audi was.
Nice! Did you notice a decline in fuel economy?
He was focusing on the wells for demo purposes for viewers. Doing other areas is a given.
It doesn't affect fuel efficiency. Not sure why it would it's only 2kg extra weight.
Good haircut, good clean shirt, you speak well and didn't do silly things for the clicks. Good job!
My truck has insulation in the doors from ford. The wheels have nothing. Blasting music and you don't hear the tires anyways lol.
Just checked the price on Amazon. About $28.00 U.S. Dollars for a 10 park. Apparently, 10 Square feet.

What about those strips or rings of expanded foam, which they have started putting inside the tires of electric vehicles? Have you tried those? Maybe an idea for another video?
My opinion: the subjective effect is greater than the decibels The noise is not only less, it is muffled deeper - this is perceived as less unpleasant
Agreed.
Toyota asked customers if the RAV4 was 'too loud' and most said 'Yes'. But when Toyota asked those same customers if they were willing to pay an extra $40 to cut the interior noise by 50%, almost all of them said 'no', they would switch brands to an inferior automaker rather than pay $40 for a quieter RAV4. That's why Toyota won't make quiet RAV4s, the customers just won't pay the extra it will take to make them less loud. If you want a quiet Toyota, go buy a Lexus instead.
If you find even smoother road dB will drop even more.
Not saying the dampening does not work but testing is done in a very bad way to tell anything true of the changes impact.
Sad to say but I was on a “good road”. We have many bad roads. Lol
But the videos are not taken at the same place. so values are not comparable.
start of measurement should be always same place, same speed, same outside temp as it impacts tire softness, and even wind as there comes whistles etc. No other cars around so best time at nigth if there is a lot of traffic otherwise in your area.
Hondas in general are notoriously noisy inside. Has been that way ever since they started selling cars here.
As a rule of thumb, a human can detect a 3db change in sound level.
So....that's a start.
1. Don't speak during a sound level check. 2. Indicate what curve the meter is testing with.
Or you can listen to some fairly loud music
What are you supposed to do if you want to have a conversation with somebody?
A larger jack (than the car's own jack) makes little difference to safety. A jack-stand (AKA an axle-stand) is the proper way to ensure a higher degree of safety (or at least, a lower level of danger).
Bulk head and dash panel outer n inner sound be sound damping than c the difference.
I’ll definitely try in a future video!!
3 decibels equals a double of energy
Or Half of the Noise in this Case!
Put same material in engine area (dashboard side ). 100 u vil c the differences.
You mean “hear the difference”? 😎
I have a video right here that proves it! czcams.com/video/cq4ojCvejq4/video.htmlsi=xYFaH_4uo72aWT3Y
My wife has a 2012 civic. Loudest car ever. My 89 bronco with mud tires is quieter. I’m 100% serious.
Turn up the radio
If you can make the car quieter, then you can turn down the radio while still being able to hear it just fine. It makes for a much nicer experience.
You're better off applying the deadening material to the fender liner itself and not the body underneath.
My 5series had sound deadening quilts on the fender liners, my 3series did not. the difference was profound. I added it to my 3series after examining the treatments done on a Bentley, 7series and a Roll Royce. All had soft quilted material attached to the fender liner and some had deadening adhesive pads on top of the wheel wells inside the engine compartment. Assuming that these companies did testing before applying the treatment, decided that adding deadening to the actual fender liner was most effective. The fender liners of 3series fit flush against the steel wheel well of the car. The adhesive dampening used in this video would have been difficult or impossible to make fit. Instead, I used a spray on product directly on the posterior plastic fender liner *not the side facing the tire. The result was significant but the sound coming from the area of the car was still not as quiet as the 5series. I later added adhesive inside the engine compartment -on top of the wheel well. The results where hardly noticeable. Note: the 3series had factory sound proofing in the foot-well of the cars interior that was similar to that in the 5series.
It's the vibration of metal panels which are all part of the car chassis/body making it seem that your inside a drum. Applying the sound dampening pads on the metal panels diminishes the vibration. Putting the pads on the plastic wheel liner did absolutely nothing.
Yes, was wondering do we really require on the plastic, when applied to the metal already.
6:39 - 6:42 🤣
I stripped the interior of my Honda Pilot and used Dynamat and sound deadening foam throughout. It only decreased road noise a little bit. The upside was that the sound system sounded a lot better and the crappy subwoofer actually became noticeable. Anyways, putting sound deadening material in the wheel well should have been my first attempt as that's where most of the noise comes from. Don't know why Honda has never addressed their issue of excessive road noise from the tires.
Take a drink every time he says “sound deadening material“ go on, I dare you.
