- This is a short video detailing the sound comparison before and after installing sound deadening (acoustic treatment) into my 76 Series Cruiser.
Showing decibel readings.
Check out my other video for a FULL installation tutorial! • How to Install Sound D...
You say it's dropped it by 'only' 5 dB however remember that decibel scale is log 10 so you've effectively reduced the sound inside by a factor of 5!! Nice work!
Phteven Phtuart thanks for the feedback! Definitely a noticeable drop in road noise that’s for sure!
From memory every 3 dB is a 50% reduction in energy so it’s heaps!
3dB is double, or half. So 5dB is 3x
5dB is a healthy drop. Would add lots of comfort.

One of the most accurate tests I've come across on CZcams(even air-conditioning is off for accurate measurements😂). Very well put together video & enjoyed from start to finish.
Thanks for the message mate, thought it was worth a shot to try the comparison
That driver’s door after deadening 👌🏽👂🏼
So much more solid
Really well done video. The testing before and after gives the viewer the empirical results.
Thanks mate. Glad I could help. Cheers for the feedback
I done this to my V6 Hilux a few years ago, made a big difference, keen to use the 3M door seal kit, apparently it makes a huge difference having a extra door seal. Good job
Thanks mate. I’ll have a suss on the 3M door kits, might be worth it!
Great video. Really like the before and after comparison and the comparison between the finished and unfinished front doors. Good stuff mate.
Thanks David, really happy with it all! Glad you liked the vid. Cheers
Great job.a mate had a 70 done before and I was well impressed lovely feel to closing the doors.definitely doors and floors mighten bother with the roof looks like a pain to do.thanks for sharing.
Cheers for the feedback mate!
Good video mate, I have just done the front and rear doors, rear quarter panels and boot floors and it has made a massive difference. My next plans are to somehow slightly bend in the drivers and passenger door frames to stop that pesky wind noise as the door vibrates at speed.
Yeah nice one mate! I didn't even think about doing that! Do you have a GXL or a workmate? You could literally just keep going if you could afford to buy heaps of boxes haha. I totally reckon the three boxes I put in are worth it though!
Defo worth it mate!!!! I have a 2014 GXL, you can basically stick your fingers up between the inside body and the door as you drive and feel the door flexing. I did try some Ebay door trim that was sorta of shaped like a "D" if you can imagine it (hard to explain) to see if that would work when the door was closed but had no luck so through doing some investigating I see some people have yanked on the top of the door and bent it in and had success. Windows would have to be down and it would only have to be a slight adjustment but seems like it makes sense to me :) Like you said, you don't want to add to much weight so doing the doors alone is a big improvement over standard!
Top video mate! Really like how you did the sound measuring, good job mate!
Thanks mate, tried to get is as accurate as a amateur can with so many variables when measuring noise! Thanks for watching!
Thanks for the video. I'm going to do a similar treatment to my Hiace diesel, which probably has even less factory sound insulation that the Landcruiser.
95db is seriously loud for a vehicle at cruise. Between 30min-1hr before hearing damage occurs.
Very loud vehicles with thin panels; plus when you add bar-work, loud exhaust and roofrack that creates huge amounts of wind noise it becomes excessive!
Great to see what parts you had the best performance from. I will be doing his on my 1997 80 series soon. Thanks for sharing!
Thanks mate
By far the prettiest offroader out there. Toyota should be smart and do a new version of this similar to what mercedes is doing with the new G class. All coils, comfy interior and maybe even an IFS version :D
You have to be kidding...
@@enterBJ40 You have got to be kidding. Everyone loves an old toyota off roader. You gay bro?
Nice land cruiser bro!! Got em sharp lines too! Love it!! 🤙🏼
Great vid This is now on my list of things to do to my Cruiser
Ray Bush haha sorry for costing you more money!! The list never ends!!!
Yea Im hearing you mate
Awesome vid mate thanks for sharing
Nice vid, thanks for making the effort to share it
Thanks mate, glad someone was able to make use of it! I’m super happy with the effects of mine! Cheers
Thank you we needed this so bad
everyone needs to remember decibels are on a logarithmic scale so 5db would be a 50% drop in perceived loudness if not more
Thanks for the educational comment! It’s a massive drop, I found it made a huge difference. It was the best measurements I could take using a phone under similar circumstances from the multiple test drives. Would be good to have been able to measure it with a calibrated instrument
Thanks for the detailed video.
Pleasure hope it helped
Great video mate, thanks. I am getting it done to a Troopy
Awesome mate! Did you buy the Troopy kit from CarBuilders or are you building your own kit?
Thank you for this video!!
Thanks for the two videos mate, really good info and honesty there.
I've been debating whether to do this or not, you leave no question now! If I can ask, is that a Toyota head unit from a different model?
razbarb thanks mate, the head unit is from VMS, who do navigation GPS software. I wouldn’t buy it again though. Probably get one of the next Kenwood headunits witg apple car play or something.
That's awesome. I guess I'm gonna have to do this at some point now. How much did it cost ya all up?
“There’s a lot of extra weight”
Pfft like 1% 😂
Thanks again mate. Awesome video. I reckon that car builders should give you a cut, i have just ordered a kit =D
Have you thought about removing the wheel arch liners and placing the mass insulation on the external wheel arches then replacing the liners - to reduce accoustic effect if you can stop the sound hitting the drum (metal skin) then it won't be transmitted into the vehicle. Basically place the accoustic liner between the noise and the skin of the vehicle....
Hey mate thanks for the comment - I didn’t think about that one! It’s one of those things that you could just keep going with, I am happy with the dampening effect that has been achieved so far. If I was building again I would do the whole firewall as well.
Good vid mate, just about to get into mine but i will be sad to lose that sweet V8 sound, wish i could keep that & lose the rest of the road noise.
haha Yeah thats it mate! Luckily, you shouldn't lose any V8 rumble, but even if you do slightly; it's worth it to cut out some of the road noise for sure! Let me know how you get on!
Great in depth vid buddy. Has it altered the sound quality of the speakers? Sound waves need a solid surface to bounce off the get the full acoustics. It’s my only concern of putting it inside the door. I hear it’s better on the door panel to stop the sound wave penetration but speakers still push good sound out.
Hey mate, sorry about the late reply - I missed this comment! Interesting! Would definitely be an good thing to compare; I think it’s made the whole shell of the cruiser a lot more “deadened” but the improved listenability to music in general is GREAT; solely from having significantly less road noise inside the cab and not having to drown the road noise out by turning the stereo up. Can now actually hear the music a lot better without having to crank it up if that makes sense!
@@4wdAdventure it does. Thanks for the reply buddy.
removing the interior exhaust noise would be the best part on my 70 series the exhaust was the most annoying part was so loud and droney
Your Toyota looks like a stud!
Get yourself some mass loaded vinyl, makes a massive difference.
mass = weight tho...
wish usa had these vehicles
I wish we had a few of yours here too! Love the big trucks
Good video mate well explained
Thanks mate
I have a Japanese import in the UK with a 2.4 turbo. Really need some sound deadening!
Maybe I can drive above 60mph/100kph without ear defenders then!!
If you don't need them, taking the snorkel and rack off will reduce your sound and improve fuel economy. If you need them though, keep them there. Smoother tires and lowering the vehicle will also help.
God job mate
i would like to do this for my '97 CRV. i wonder how expensive it would be to have it done?
BruceTheSillyGoose $150 per door near my house in Atlanta, looking to do it my self
Great video bro. Go the troopy.
Now that you have had it done for a bit did you also notice it have heat benfits in summer ?thank you
Thanks mate. No noticeable difference, the aircon in my 76 is really good so it’s hard to tell. The biggest improvement for temperatures was dark tint for me!
nice rig
So after all this time how well did it help with keeping heat out in summer and heat in in the winter
Thanks for the question. I don’t really have any measurable data in regards to temperatures. I think the dark tint plays a big part in keeping the cab cool in summer.
I definitely noticed a different in temperature coming from the trans-tunnel and with less heat emanating from around the gearstick into the foot wells. I guess adding any extra insulation would help with temperature retention, but I find the aircon unit in the landcruiser very efficient in all conditions anyway.
@@4wdAdventure well I went ahead and did it in my floors, doors and roof as well and i can tell from owning so many jeeps that it holds heat a lot more now than it ever did before and that the heat from the trans tunnel is now hardly there
Awesome!!! Glad to hear!! Thanks for the reply
@@4wdAdventure thanks for havin the confidence to make the video my man
I sound deaden my 2019 rav 4 floor, doors, trunk, the sound Decimals hover about the same as before about 77 I did notice a little bit less noise but not much but knocking on the Vehicle sound was solid and it drove tighter, I only used one layer , a bit Disappointed it was a lot of Work to do it , it could be my fault
gary tardiff It Is a big difference when you put one, two or three layers
What did you put in? From my experience foam mats lower db more than bitumen stuff.
Nice one!
Hi mate. Great video.
Have a question non related to the insulation. What stereo do you have? I want to install one in my 76 series.
Cheers.
Thanks Oscar, I have 2x Sony 6x9 speakers in the wagon, 2x Sony 6” speakers in the rear doors, 2x Sony 6” speakers in the front doors, 2x Sony 4” speakers in the dash and a 10” MTX sub in wedge box (to suit the angle of the rear bench seat in the back). I have rewired all the speakers with new thicker gauge speakers cable. All 4 door speakers and the sub are running off a 500w Sony amp under the back seat powered off the ignition. And the rear 6x9s and dash 4” speakers are powered from the headunit - this is so I can have music playing while the car isn’t running and I’m not worried about extra speakers/sub and amp draining the battery. The headunit is a VMS in dash GPS which fits the space. I would recommend getting a newer unit with Apple CarPlay support and just using google maps through your device. The VMS is old technology now.
Hope that’s helps!!
Didn't the doors just do another 1-2 db but the stuff you did first did about 5 db?
Aren’t you supposed to roll in the bumps?
Yeah you use the roller to go over everything to press it down and make a good seal
Toyota land Cruiser 70 series heavy-duty the best of the best 👍 👍 👍 👍
Super bravooo
How much do you think the total weight is that you added in deadening?
Exactly 18kg - 6kg per pack
Bit off topic but what snorkel you using?
Wytch Hunter it’s a custom 4” stainless steel snorkel but powder coated matte black. Got it from CAM Fabrications. Found them on Facebook.
Nice video but you compared the before and after part during different times, day and night.. don't know what difference the temperature of the road made on the noise levels..
Dang, 88 is still causing hearing damage, but a big improvement
will it work for compact / kei car?
Did you apply any to your engine bay?
Nah the engine bay on the cruiser is so jam packed it’s almost inaccessible. It would be possible, but I never looked into it!
at 1.11 you have a dead dog on your front lawn mate! :)
How much did this operation cost?
About $500 all up I think!
1:21 Dog Is Not Included.
Haha dogo was absolutely no help at all!
another q, will it add significant amount of weight? N materials total weight ?
total weight for my cruiser was around 18kg
How can you get an accurate reading.... you keep talking over the meter..
I was only talking the short time while it was being filmed. The sound meter was on the whole drive at the same speed and driving conditions and that was all being recorded too. Obviously never going to get perfect conditions for audio recording or a decimal point accurate reading on sound difference; was just trying to give everyone a rough ball park figure of acoustic improvement
Hey mate, what rims are those?
Allied Wheels Savannah Black
@@4wdAdventure thanks chich!!! They look great
One more question mate, what offset are you running. -5 or -50. 16 X 8 yeah?
16x8 yup, but running 0 offset all round
What kinda wheels are those?
Allied Savannah
도요다76구입
Yeah... it did sound tin-nie. LOL
Radio off, AC off, windows closed but drivers mouth not shut for a proper reading...
