listen. i don’t know how you know that i was presently communicating with the potential maker of my treatment… but this video comes in at a KEY moment in the decision making process.
and the key points about varying thickness which i was trying to make a point about to a colleague saved a lot of arguing 👍🏾
Ahh. So you too have experienced the “this channel uploaded a video on the specific thing I was thinking of” moment. Happened ti me not too long ago. Welcome to the club. Kinda scary, ain’t it?
Thanks! Great video, Kyle! “Tuning” a room is truly an art form. Some high quality studios have fold out panels which allow tuning. There are so many variables while recording, pending on the genre and scope of the recording. I think most beginners overlook that aspect. They don’t take the room into consideration as being part of the recording. I am in the process of building a studio with less than ideal dimensions. It also has lots of windows. Tuning it is going to be a challenge. Hanging panels and bass traps will be part of the tuning process. I am going to hang large wooden, adjustable blinds over the windows which will be used as diffusers.
You know my broke ass does? I buy a whole bunch of eye hooks and screw them into the stud all around the top perimeter of the room, and then I string up a clothesline. Then I use clothes pins to hang up a bunch of towels, old blankets, and/or whatever I can find. It works well.
Love this.🥰I'm basically recording for myself. I don't need perfect, and I'm not looking to make money off it anyways. I don't like spending money where I don't need to. Thanks for the idea.
So far I only do voice over for CZcams videos in my “studio”, so a lot of this is overkill, but it’s really interesting to learn about and it gives me a better understanding of what actually would be beneficial for me compared to what’s more aligned with someone working with more complex audio work. Thank you so much for the easy to follow tutorials for a complete noob to the audio world!
diyourselfperks made a good video about this: folded towels on wooden planks in the corners are a great and cheap audio-treatment option. It works much better than the most commonly used tiles by people who have a bigger CZcams channel.
Depending on how thick the folded towels are and the breathability of the fabric, this could be a good solution. However, insulation and wood might be just as affordable as towels and wood.
@@AudioUniversity Noted. 👍But be careful with the insulation material not being toxic. 😉
@@peterjansen4826your house is full of it already. If you’re not smacking it daily, it’s not going to be releasing fibers everywhere. Don’t waste your time with towels or anything, just make some panels they work
@@tylerhackman6832 Sadly we have used many toxic materials in many people's houses, not only asbestos. 😥I don't state that you should avoid it, I merely caution to research if the chosen is safe and to take into consideration that we might not even know it yet, that is all.
I've been waiting on this subject from your channel!
Nice and well explained.
It's so many people who don't understand that with thickness and distance to the wall behind (they cover the walls with absorbers that are way too thin and with no air gap to the wall behind) - this will probably save a lot of money and disappointment for many.
Another tip is to use the corners between walls and the ceiling for large absorbers and for panels put at an angle across those corners - there is often a lot of unused space there. That way, the low frequency absorption can be improved a lot without take up too much of the usable space in the room.
Just read up about sound absorption with vibrating panel absorber.
The thickness isn't he key point.
I freaking love this channel
My studio is covered in a mix of GIK stuff and DIY stuff. I have to say, the GIK stuff is amazing. Theyre pretty affordable compared to other products, and the look and quality are impeccable. If you have the money, their stuff is totally worth it.
was just wondering this like yesterday lol, thank you
Nice video as always, question is, panel should fill entire height of wall or 2x4 feet size enough?
That is a terrific explanation of absorption thickness and its relationship to wave length. I really like the idea of an air gap behind the panels also. Thank you
Read about sound absorption with vibrating panel absorber.
The thickness isn't he key point.
Perfect timing, thanks for the video
Thanks for watching!
Thanks for informative video. I've been wondering how much reverb is right for a room where it's mainly used for vocal singing and acoustic guitar and if a little natural reverb for recordings is better than recording in a vocal booth?
5:51 I'm so glad that you mention this. Straight outta Toole's book! :D
Really good video overall, I'm glad to see such an accurate and informative video among all the nonesense on youtube.
The only thing I'd change would be to normalize the waterfall graph. Sure, resonances show up in the magnitude response, but this can be fixed with EQ, so I think it's more interesting to look at temporal anomalies (decay) isolated from the magnitude effects.
I'm hoping to see a segment on MMM and room EQ in the follow-up video. Your room EQ can only be as good as your measurements are, and single point sweeps certainly aren't it ;-)
Good on ya Kyle keep up the good work 👍
Thank you!
Just read up about sound absorption with vibrating panel absorber.
Yeah! “Active absorption”. Pretty cool stuff!
Hmmmm... I have added additional rugs or even a sound blanket under my mic so its good to know this info.
GIK are great and they offer a free acoustic advices! Well made!
Great 👍 video, Kyle.
Thanks!
It would be interesting to see how well the tuned membrane bass traps work, to lower that 40Hz decay time.
Excellent as usual, Kyle! Did you ever produce a similar video for home theater applications or are the principles basically the same? Thanks!
The principals are the same. There are just more variables in multichannel home theater systems. Check out this playlist: czcams.com/play/PLASEfdY-tiDqM1Bmljcl3WBHXJUclBkiK.html&si=qrU3kdxQ-s2CxIv_
@@AudioUniversity Thank you!.
Sod it! Was going to build some 4inch deep panels using the hemp equivalent of rockwall. Might just buy Slate VSX platinum on sale and save all the hassel and space. 😂
very informative
Kindly make a video on how to deal with echoes in church. Using acoustic panels or any othe
r knowledge you have
1:11 dam, was hoping the panel color was the big benefit...
Actually, this is great advice, thanks!
maybe acoustic treatment on an absolute budget and using old cloths. like; towel. thick blanket or stuff
I just posted a similar comment. That indeed. A room filled with bookcases and all that also works well, certainly if those cover the corners.
I did the same thing in high school - hung blankets from floor to ceiling in my parents’ basement. Looking back, I should have folded the blankets to make them thicker (even if less wall was covered). A towel will only absorb VERY high frequencies with wavelength 4 times the thickness of a towel.
@@peterjansen4826 i thought that help like disperse the sound or something like that
@@AudioUniversity so. is towel not very best at acoustic treatment?
Fire hazards.
the more I'm studying how to treat my room the more I just want to use headphones :D
Really interesting. One thing that I would really like to know: As an engineer at heart, I love seeing numbers and I understand about using REQ (room eq wizard) for configuring speakers and audio systems, but I'm recording CZcams videos in a home office - primarily single person, talking head setup and I want to measure and then reduce reverb.
I assume I need to understand what reflections are reaching the microphone recording me, but how do I measure that? Do I mount some kind of speaker to mimic where I am standing/sitting and talking and play test tones, standard audio tracks, or a recording of my voice? What type of speaker/audio system setup, what volume levels, etc. as I assume for testing I need a standardized audio source for repeatability as I test various changes to the room?
Check out this video: czcams.com/video/uCFqMfg7tM4/video.htmlsi=2PzhLY0S4MbU2OfB
This is about speakers to listening position, but the same principle applies between talking head and microphone.
For a vocal recording booth, would it be better to line the area with the 2” foam pads or put up panels like these?
Depends on the foam. Most foam isn’t very effective in absorbing acoustic energy. I’d recommend thicker panels in the particular areas where the reflections will be shortest if it’s a budget thing. If it’s not a budget thing, go with panels.
Something not considered- foam degrades. Even the polyurethane crumbles to dust.
Most panels seem to be covered fiberglass or mineral wool. Probably better long term.
For a booth a mix of diffusors and absorbers works best. The bulk of it should be diffusers. The problem with booths is by the time you control the reflections the booth is acoustically dead in the high frequencies. Since you are so close to the surfaces look for 2D diffusers which reflect the sound back in a hemispherical pattern at a reduced level. I have used RPG omnifussors and BAD panels in these locations. It looks like GIK has 2A Alpha Series Panel Diffusor/Absorber which might work like the BAD panel I do not see any test data to verify. The Gotham N23 5″ Quadratic Diffuser might be close to the omnifussor.
@@dannelson6980 thank you very much for this info. I appreciate it
where would you recommend to put acoutic tiles/bass traps if you had a full drumkit in a room against the back wall? there's at least a 3sec reverb even when you clap!
If you’re trying to reduce the reverb time, you’ll want panels all throughout the space. But you can probably get some added clarity by addressing the back wall and other short reflections from the drums to the mics.
@@AudioUniversity cheers, I'll try that
whoa, you killing it with the audio, but this vid is overexposed today
Acoustic Fields channel has great videos on this topic. In my own opinion I believe it's a rabbit hole. There are too many variables that influence the sound for the end user. So unless the engineer can invite the end user to their studio to listen to the recording I don't believe it really matters. I can say on some professional recordings that a particular frequency or instrument may stand out and I find myself wondering if it is intended or a result of the recording or mixing/mastering. Or the method and/or location of how I am listening to the recording.
Is this netspends big brother ??
I’m having a hard time seeing the difference between the with side panels and without side panels impulse response graphs. The narration says “brought the level of the reflections down considerably“, but it looks to me to be almost imperceptible…?
There are some spikes in the “without” graph that are not present in the “with” graph. I should have circled them!
If anyone wants to donate a few bass panels to me I’m always here.
Honestly the differences in those measurements in REW doesn't look like much of an improvement, if at all.
However, what you actually hear in person (or some binaural recordings other channels have made), seems to be much more significant, there's certainly some mismatch between how microphones and graphs look at things to to how our brain interprets the direction of a sound and the size of a space it's in just by subtle changes.
Keep in mind: these graphs only show the difference with and without SIDE PANELS. All other panels are in place for both measurements.
GIK are amazing
ROCKWOOL 100 x 600 x 1200 mm, 2,16m² = $14 where I live
Really good content as usual, but annoying background music and ‘flickering’ video.
! So what about in your Vehicle? You Can't put 2" or 3" sound Panels there. Also does the Butyl adhesive like Dynamat or Kilmat etc Actually Do Anything at ALL? Is it worth it? Can you Use A Cheaper Substitute? What is the Actual Wavelengths of road noise and thickness of material we should Use to Block it out?
Blocking noise is much more about rigidity, isolation, and seal. This video is mostly about absorption for making the sound IN THE ROOM sound better, not keeping sound out or in.
Heads up. Your end screen is messed up.
I don't know if you got a new camera recently, but your exposure has been too high lately. It makes your skin look pale-y white or even white in a lot of the shots. Also, your focus is off. Might want to adjust your aperture if your goal is to have your desk and you in focus. (Just your keyboard and mac are in focus)
I'm not saying you should, but room correction saved my room. Panels/foam on the wall is just polishing a turd. It will cut down on reflections and smooth out the rooms eq curve, but you've still got problems. Unless your room is big and round, you've got standing waves. EVERYONE has a dip and bump in the low end. I have 12" thick dense foam covering my entire ceiling and 6" dense foam covering all my walls and I still had a 10db dip at 100hz. This is the reason nobody can get the low end right in the mix. Not to mention speakers being out of phase. Mine were not, but lots of people's are. I used ARC 3 with a $35 Behringer measurement mic and it changed everything. Good luck homies!🤙🏼
I also use and recommend corrective EQ, but acoustic treatment can treat problems that cannot be treated with EQ. Check out this video: czcams.com/video/tqkMUOD5FUI/video.htmlsi=lr8GKVYJxRtPgBB4
if you have an extinction due to overlapping waves then an EQ cannot correct this.
adding more tonal energy retains the error.
@@c.p.2807 I'm not sure what you mean, but the correction software isn't just eq, It corrects phase as well. I'm not sure the exact science, but I can hear, feel, and see a difference. There are two mixes of the same song, on my channel, that were done before and after room correction. Now, I'm not a pro engineer, so I'm not touting the mixes themselves being amazing, but you can clearly hear the sonic difference, and it is exponentially better. I know everyone is an expert, so I'm not doubting your concept, but I'll let my ears tell me the truth. The correction software also offers the possibility to tweak the curve to the end result you want. For instance, my mix seems a little high end heavy, so if I can't self adjust, I can adjust the curve. Either way, I'm sold on it.
What the fuck happened to the subtitles??
I don’t know, man, the audio reflections didn’t sound very good the very first second when I clicked on the video.
That’s the reflection from my computer monitors… still trying to find a good solution there.
@@AudioUniversity I see. Well, tight polar pattern, close to mouth. Or monitors further away.
There's no acoustic panels in nature....
Whoah, really? Just FYI there are no box-shaped rooms with perfectly parallel walls in nature either. But that's usually the kind of space where we end up making and recording music. So... 😉
Alternatively, invest in speakers that load your room correctly, rather than using costly solutions to compensate for your systems inadequacies.
When I first got into hi-fi in the late 70s, room treatment, acoustic correction, DSP, were never factored into the hi-fi equation. That didn’t prevent us building world class sound systems!
At a certain point, acoustic treatment will give you far more drastic results than different speakers. That’s especially true in rectangular rooms. All speakers are going to cause reflections and excite resonances in the room.
Exactly the response I would have expected fron a video promoting an acoustics treatmemt company. Acoustic treatment can only alter a room’s sonic characteristics. Whether those altered characteristics are preferable, is surely down to the listening preference of the end user. For most of us, who don’t have the luxury of a dedicated listening room, whose hi-fi has to fight for it’s right to be in the family lounge, RT60 levels are normally kept within acceptable limits by the soft furnishings, sofas, curtains, carpets, rugs, people and pets. Dense foam filled easy chairs and sofas make for highly efficient and effective bass traps, believe me. When I updated my 2 and 3 seater leather recliner sofas for fabric, dense foam filled static sofas, they killed the room. I had to rearrange the speaker placement and add additional subs.
It’s about more than the overall RT60 levels. There are room modes and spectral reflections. Of course there is no telling what someone prefers subjectively. But on an objective level, some problems require acoustic treatment, some problems require different speakers.
I won’t argue about the legitimacy of my advice - my track record speaks for itself. Take the free advice or don’t. Acoustic treatment (if possible) will give you a bigger improvement for less money invested, assuming you have decent speakers and amplifiers.
@@AudioUniversity I’m not knocking your free advice, or expertise. I simply refer back to the point I made in my initial comment. When I got into hi-fi in the late 70s, acoustic correction, room treatment, DSP just weren’t ever factored into the hi-fi equation, but that did not prevent us enjoying a premium listening experience, regardless of the room.
Hi are you able to understand that only you use those measurements system? The rest of the world uses meters, kg etc. Maybe it would be great if you could finally show on screen both measurements? Is it that hard American guy?…
And yes I’ll ask Siri 6ft to meters. But you could give better experience for your audience!
Damn… Americans..
