Acoustic Panels - What & Where

[@annekedebruyn7797]

@@BojanMarusic The point of treatment isn't creating a dead room or a room for voice over. The point of that room is to remove problem areas from the speakers to your ears. A dead room is terrible for good sound.

[@annekedebruyn7797]

@geluidsoverlast Not really. You will make your room too dead which is not something you want. You will just waste your money just like on foam. Better to do it correct the first time and in a lot of cases, rockwool is much cheaper than the thickness you'll need with curtains. (30 euros (40 USD) a pack of 8.) Also a positive thing is that the rockwool acoustic panel designs will stay with you your entire life, making it convenient when switching places or situations.

[@annekedebruyn7797]

@geluidsoverlast You are joking right?

[@Oneness100]

I don't think it does. the curved piece is not a diffusor, it's a redirector and it's not really diffusing the sound like a Quadratic Diffusor. Plus, why would you want sound to be pointed downwards and upwards due to the orientation of the device? I have never seen a video, this one included, that's going to be able to cover everything you need to know in 5 minutes. Acoustic treatment, acoustics, etc. is NOT something you can learn in 5 minutes or less. Too much to consider. I will suggest going to another site that discusses things in easy to understand terminology, but addresses a lot of myths, misconceptions about room treatment and goes after what the problems are and how to really address them.

best video for acoustic treatment i've watched so far.

[@stevo728822]

If you want a better understanding of how sound waves behave then I suggest taking a trip down to the beach and study how sea waves behave when they hit an obstruction. A strong sea wave will reflect back off a flat sea wall but against other protruding obstructions the wave will often split into two or more waves, each new wave carrying less energy than the original. A sea wave hitting a group of rocks will be broken up into many more higher frequency but lower energy waves. Higher frequency (but lower energy) sea waves can even be absorbed by dense mats of sea weed. Sound absorbing materials (earthwool, foam, rubber etc.) are performing the same role on sound waves as the beach obstructions are performing on sea waves. Sound waves are of course travelling much faster than sea waves at about 340m per second. So a single sound source will be received by your ear many times in a room due to reflections until it is absorbed by materals in the room. As with sea waves, each reflection off a room obstruction will often split the originating wave into one or more new sound waves. The lower the frequency of the originating sound wave, the more reflections it takes before it is all absorbed (because more energy is stored in each lower frequency wave than a single higher frequency waves). Since they contain more energy in a single wave, lower frequency waves travel further, a characteristic that whales and elephants use in communication over long distances.

You can do it in home by having some water in the round bucket and dropping pebbles or stones in it. I used this to study Huygens wavelets, that big wave and small wave stuff. Always remember Transverse waves differ from Longitudinal waves in Nature, especially refraction and reflection, Free end vs Fixed end.

[@Aaron_LH]

It's probably worth mentioning that some experimentation should be employed here. I understand this is meant as a brief overview but yeah. Getting a microphone specifically designed to analyze your rooms acoustic signature and some software to disiminate that information (Room EQ Wizard is a wonderful tool and it's free) will pay dividends when deciding on the placement of your panels and diffusers. If you're going to do it, do it right. I find it also helps, as a mixing engineer, to know exactly where in the frequency spectrum, the issues in your room lie. Helps to avoid certain mistakes when navigating a mix. For example, I know not to fret too much over a lack of bass in the 80-100hz range because I can see on my graph that my room has a reasonably deep null there.

Will the "mirror trick" work the same for finding the reflection point with a drum set? I was thinking compared to a speaker, the sound would be more omni-directional with a drumset compared to more directed like a speaker. How would you determine optimum placement for panels for a drumset?

[@Acousticgeometry]

Drums are tricky - the sound-dispersion patterns vary, depending on whether you’re placing mics on a single drum, a cymbal, or the entire kit. As a former drummer (now a drum owner), my goals were different than when I became a recording engineer. For recording, I’ve found that Curve Diffusors are best placed vertically on walls at the points nearest the kit, and on ceilings horizontally over the cymbals, obviously depending on where mics are placed. Best positioning for absorber panels would be in any corners near the kit (on each corner wall), directly over the snare drum on the ceiling, and next to the Curve Diffusors toward the outside of the kit. The great thing about our Z-Clip-mounted panels, both absorbers and diffusors, is that they’re modular and can be moved easily to try different placements. Some studios even use our Combo Stands to easily relocate the Curves on the studio floor, depending on the type of drummer and kit. I hope this helps - let us know if you find any “best panel placements” - and thanks for your question! -John Calder

@@DONK0 But will they be Phase Coherent! :P

[@Oneness100]

@@DONK0 The problem is three fold. The materials you are most likely thinking of using might be toxic and not meant for room treatment but rather building insulation. Building insulation for the most part emits tiny particles in the air (even if they are wrapped in fabric) that can cause health issues. The other factor is the absorption coefficient curve. Sure, you can use them, but they might over absorb In frequencies between 125hz and 500hz where it's not that natural sounding. There are acoustic open cell foam that has a much smoother absorption coefficient curve between 125hz and 500hz that will give you the most natural sound as that range is where absorption panels differ.. The other MAJOR problem is with low frequencies under 100hz, that's the most costly to deal with, you do need lots of "boxes", especially if you are dealing with loud SPL levels of low frequencies. And just sticking them in the four corners isn't necessarily going to solve your problems. you can see how bad of a problem you have by measuring low frequencies in 10hz increments from 20hz to 100hz about every 2 to 3 feet around the perimeter of the room, and if you map out the results. you can see patterns emerge where there are room mode issues that alternate about every 2 to 3 feet and you really need to treat the entire wall for optimal results. People have to be careful not to put too big of a speaker system in small rooms, adding subs and not properly adjusting them into the system, or having too small of a room for the room usage.. Ultimately what is your goal? To have a room with a flat response curve with proper TC-60 reverb time signature? If so, then you are going to need a good sized room with relatively high ceilings to give you enough space to properly treat. Just sticking $15 panels around the room isn't going to fix the acoustic problems in the room. Will it be better than an untreated room? Sure, but it's not going to be a well treated room by sticking $15 panels around the room.. They aren't going to fix all of your problems, even though it will sound different. Don't confuse a different room sound to good room sound. I wish I could have you visit a room that's really designed and built properly with treatment that really fixes the problems in the room. The results are stunning. But it's going to cost a LOT of money to do it right. I've seen rooms that were custom built from the ground up that were truly insane room acoustics where it was pretty close to a flat response curve and a near perfect TC60 reverb time for that type of room usage for a pair of relatively large speakers. the room cost alone, sans stereo equipment, was in the neighborhood of $450,000. Yeah, to 99% of the population, that's too expensive.. to get a really good improvement that most people would be happy with, it would cost around $25K in room treatment to get a really good room sound. But it still requires a certain room size to begin with. Can you get really good room sound for under $1000 in treatment? Probably not unless you don't turn your speaker's volume up that high. It's when you turn the speaker's volume up to a certain level is when the low frequency problems start to emerge, etc. If your room is big enough where you have at least around 7' to 8' feet or more between each speaker and the closest side wall, and you keep the SPL fairly low, you can do close monitoring where you don't need room treatment, because you have enough distance between each monitor and each wall and you aren't exciting the room with low frequencies causing problems because the SPL is low enough. But that's typically not the case for MOST people.

[@TheEchelon]

Oneness100 Yada yada yada. Most of these expensive pre-made options aren't optimal as well. Many advertise absorbers as diffusers and vice versa. You could also use upholstery foam instead. They come in different densities. If you know what you're doing, you can get very close for a fraction of the price. It's also fun to DIY in my opinion.

[@kerimtim]

Thank you for the video. I have a question: Shouldn't you cover every single wall entirely? or just making a few frames, is enough to absorb any unwanted reverb?

[@Acousticgeometry]

Hi - thanks for your question. Three points: 1) You want to retain some of the room’s natural ambience, so removing all reflections/reverberation creates an anechoic chamber, which is an extremely difficult sound environment for humans; 2)All sound absorber panels have a limited range of frequencies they can absorb - most fiber-based absorbers (fiberglass, recycled cotton, wood/mineral fibers) absorb well at high frequencies but not well at mid- and low-frequencies. This creates an imbalance in the sound in the room. 3) We always recommend a balance of absorber and diffusor panels in a room, because it reduces echoes and reverberation and spreads out the remaining sound energy so the room feels more natural.

A question I have always had. I live in loft so I have neighbors. I can't really play my stereo very loud at all. Do acoustic panel make just as big a difference at lower volumes as higher volumes? I was just wondering if it was even worth the time and money in that situation. Thanks

[@Acousticgeometry]

Thanks for the question - it's one that we're often asked by apartment and condo dwellers. While soundproofing and noise control are difficult to implement in multiple-dwelling units, due primarily to the cost and shared structural issues, in-room sound is a different matter. While room treatments won't reduce the sound leakage in and out of the space, treatments can improve the quality of sound in your room quite a lot, even at lower volumes. We favor Curve Diffusors (bit.ly/agcurves), sometimes on Combo Stands (bit.ly/agcombostand) depending on the room situation, as they offer the most sound-improvement-per-dollar. If you'd like to send us your floor plan, we can recommend a room treatment setup that should greatly improve your listening experience. We're available at [e-mail] Thanks, John

[@mrhoffame]

Acoustic Geometry Thank you so much for the info. I will do that!!

[@nikhbit]

Hi mrhoffame, I think that if you installed the absorbers for reducing the sound, that would be effective at mid-high frequencies and low frequencies (bass) aren't shielded off completely. Hence I suppose your neighbors will still be faced with some low frequency annoyance if you play with loud volumes. Hope that helps. ~Nick.

There is a bay window which we had to insulate and bolt in moving blankets and hung moving blankets are hung over the window. This greatly cuts down the level going outside, but the problem sound is traveling out the front door. That is where it is the most audible from outside. I am thinking that the Auralex Sonalite panels should go in the corner where the drums are usually at. All of the absorbing material can be taken down. We plan on moving everything to the basement, but we have to wait for spring cleaning and some light remodeling first. I was thinking of spreading out the tiles 2 on the corner staggered and 2 by the front door, but I am not sure, if the absorbing material should be closer to the source?

Nice video. And I really enjoyed the "How Sound Works (in a room)" video too. But I don't understand why there is so much echo in the sound as captured by the camera even after room treatment here. Obviously, John Calder and the mic are not "ideally" placed relative to the panels. But at least, wouldn't all those diffusers and absorbers scattered in the room have *reduced* that effect ? As a last question, could someone elaborate a little why diffusers are/can be a better option than absorbers in the primary reflection point ? Is this only an advice for restitution environment, or this can be considered too in a recording or mixing room ?

[@okidot]

Having diffuser at the main reflection point will diffuse and reflect the sound waves in a much more dispersed manner, which means standing waves can't build up as easy, and has the same perceivable effect of absorption. A diffuser on first reflection point would be a good solution for a room that does not need too much treatment, as dispersing the initial reflections might be all the room needs. Otherwise a diffuser on first reflection in a bad room with lots of reflections to begin with, it just complicate the reverberation. This is why absorption on first reflection is important to try and reduce the overall room reflections.

[@woscar84]

if im going to film videos and im going to move, is there any special treatment for that, or whats your advice?

[@theshopper6902]

At what height should panels be mounted on the walls.

[@jacobsmith1877]

Do they come in different colors?

[@yeon723]

does that formation work for lousy upstairs neighbors?

[@Mickimoss]

What kind of material is a diffusor?

[@stjernholmreviews]

Very good video!

[@goodsound4756]

And how does this work with dipole speakers like Magnetostats and Electrostats?

[@pronavsandhu]

whare can i get that assistant from?

[@glengatt3941]

Can you fix a problem with such material I don't have enough room for my rear ported speakers I can't get more than 6 inches from the wall

[@baluxyanahiam3630]

Just learned a ton in 3 mins & 35 secs.Wow !

[@kenvandeburgt1232]

I'm having problems with low frequency environmental noise - including tonal 17, 22, 60, 120 Hz and incoherent noise 0 - 20Hz. Is there a way to refit exterior of house to prevent the noise from causing structural vibration and wind turbine syndrome like effects (tinnitus chest pressure, nausea, tingling sensation in extremities) inside the house? I'm pretty sure the source is machinery at an MMAR grow op (probably heat pump or exhaust fans) ... but haven't been able to figure out how to prove it.

+Ken Van de Burgt To absorb low frequencies I'm going to experiment making sound panels using fine steel wool in combination with earthwool. The higher density of steel wool over earthwool should capture more of the lower frequencies. Also take into account that half of what you hear is sound reflections off solid flat surfaces. Speed of sound is about 340m per second so our ears receive the same sound not once but something like 10-20 times in 1/10th of a second due to these reflections in a typical sized room. Breaking up flat surfaces will also split low frequency sound waves into several higher frequency sound waves which are then easier to dampen. You can see this effect when a water wave at sea hits rocks or a groyne. The wave is split into two or more waves, each new wave containing less energy than the original.

I have a home studio and am thinking to just use four absorbers, a couple of diffusers and a couple of bass traps, and then use Sonarworks for room correction. Then I'll take the stems to a pro studio with a mixing engineer and do the final mixes there.

[@LBibeauB24]

What about placing, say, carpet on every square foot of the room? Does that work in the same way or would acoustic panels work better?

[@Acousticgeometry]

Thanks for your question, Lakoda, Carpeting, whether on floors, walls, or ceilings, has very little sound absorption except at very high frequencies. That means it’s an ineffective room treatment for nearly all sound. Purpose-designed sound treatment panels, like our Fabric-Wrapped Absorber Panels and Curve Diffusors, are far more effective for controlling sound in rooms - and our treatments will look a lot better than covering your room with carpet. Well, except for classic orange shag… Thanks again and best wishes, John

[@LBibeauB24]

***** Interesting. I'll try that before spending money on panels. However, my studio is now in a rather open concrete basement. i have the back half dedicated to music and my computer... that would be a lot of quilts. Should I just quilt the wall that the amplifier is against and the back wall perpendicular to it?

[@dcfincher]

What about bass traps? Do you recommend those?

[@randomstranger4992]

I have a room with just a drumset in the basement and the sound is really bad ... how do i make it sound better? When i play,it fells so loud and the sound is really bad.. could u help me?

[@1dpaisley]

OK I have a question. I am putting a home studio in the front office of our home. I am a lifelong musician and I think that this is a great video. So my question is… Couldn’t I just Cover the ceiling and walls with acoustic foam and be done with it? Lol! I have a very good budget to work with.The company foam factory has very reasonable prices. I run a teaching studio in a building near my home. I did this and it sounds great. I can’t use it for recording because it is too close to the damn train tracks. Suggestions? Thank you in advance.:)

[@jessicaverdin6309]

Really helpful video! I cried laughing at :49 in the video - pure gold!!

[@engespress]

Just fill up your room with junk. My house has got fantastic acoustics because it's so cluttered.

[@A.456-c8r]

What's the purpose of diffusers exactly? They don't absorb reflection as absorbers. How do they enhance acoustics exactly?

[@HunterShawMusic]

They scatter reflections so they take longer to get back to the listening position, getting there at a lower energy level. It makes the room sound bigger, and reduces the comb filtering caused by early reflections.

[@beausky4100]

Acoustic Geometry these acoustic panels are only applicable to close or sealed rooms? thanks

[@johncalder8490]

Our acoustic treatments (both absorbers and diffusors) will work in many types of rooms, including open-plan and open-ended spaces. While soundproofing products only work when rooms are fully enclosed, wall and ceiling treatments will help improve listening spaces of nearly any type. The suggestions in this video will improve the sound in your room almost regardless of shape, though some alternate placement considerations might be required. Thanks!

[@beausky4100]

@@johncalder8490 thank you, sir john

[@bobsmoot8454]

Another reason to use corner horns/speakers and make sure your corner speakers have directional control to ensure no more than 90 degrees of dispersion

[@kenny7762]

Im a bit lost are the diffusers naturally grown or man made ,i must admit you just can't tell and they dont make alot of noise

Best video about this topic!
