You have taught me a lot. I’ve been building my home Theater room in my house and I’ve built my format from your videos. I can still use some advice but, thanks for your no nonsense teaching.
I have seen these often in factories just separate areas where there is very loud machinery running from other areas of a warehouse or a factory where the machinery is not present and they don’t want people to have to wear hearing protection. It is amazing how well they work with that type of mechanized noise that typically is relatively high frequency rotation of motors and assemblies (1-2.5k) It’s not that you can’t still hear it on the other side of the curtain, but when you walk through or drive through it with a forklift… Right on the other side of it it will be so loud you need hearing protection. And just on the other side of it you didn’t. And it also serves the purpose in a lot of cases to keep HVAC in a room separated from another room that is unconditioned which is another convenient feature.
The noise requirements for factories are completely different than for critical listening rooms. I suspect anything would be better than what most factories have.
I , Remember that every material used in acoustics is frequency and amplitude dependent. This means that it will only "work" for certain frequencies and amplitudes. There is no one size fits all situations. Its just like anything else you use science to solve. You measure with a simple device such as an iphone. You measure what frequency the noise is at and how much noise there is. Qualify and quantify the problem then design the solution based upon the problem. No need to guess. Use science.
@@laurabrown5288 Good idea Valentina but not really a problem a lot of people have. I think in general most people are not too concerned with their room's sleep. How do we even measure that or care?
What made a big difference in my carpeted room was placing curtains behind and on both side walls 6 feet out from my front speakers, I also placing my sub to the side of me, against the wall 4 feet away. The difference in doing these two things made a big difference in sound quality, especially in the sub which I originally had in the corner of the room by my front speakers, it made for louder lows but it also made it boomy and fatiguing. Now with the sub to the side I can feel the sound more then hear it. The curtain helped tame the mid to high frequencies. Side deflections are not a big issue but still could use a little help. What I like is a lively room, so some side deflections is a good thing. It's work in progress but I like what I hear now, Thanks to knowledge I've learned here.
In my home theatre, I have windows on one of my side walls. Since I cannot install acoustic panels on this side wall... Would curtains control or prevent the primary reflections?
You can not prevent reflections from a surface area. You can miimize their sonic impact by using the proper rate and level of absorption. You can use curtains. However, they do not have measured rates and levels to work with. Stay with a curtain that has a minimum density of 26 oz. / sq . ft.. Makke sure to use the same material type on each wall.
These will work. Sorta. But they are not very effective. I know, I tried something similar in my home trying to block out noise from the street. To block sound you need mass. Stuff has to weigh a lot. I finally went with very thick tempered glass (like on glass top coffee tables). Weighed a ton, and was very effective blocking sound (or damping if you will). For walls and ceilings you can do a lot of complicated and expensive things like resilient channel, sound clips, green glue, all that. I did that too, but the easiest and most inexpensive way is to use 2 or 3 layers of drywall and stuff a lot of insulation in the wall space between studs. Want more at a small price? Go w/ double thickness studs (2 pieces of 2/4 studs instead of one), double the insulation, and 2 to 3 layers of 5/8" drywall, which is about $13 a 4x8 sheet.
I have cars constantly driving fast and can hear their exhaust around this time which is 2:45am and it’s hard to sleep I’d love some quietness and I have a big window I need help bad it’s Ben going on for months now and I’m literally loosing hair for this it’s getting out of hand
J, Noise has to be measured. You must know what frequency and amplitude you are trying to isolate from. We need maximum and minimum pressure levels because we need to design the barrier to provide isolation from a worse case. We can assist you with this process. You take measurements under our supervision with your cell phone and then send those numbers to us. We then design the barrier based upon your measurements and send you a drawing so you can build the proper barrier.
Long time fan here! Question. Ive heard windows serve as good outlets for bass. Would placing thick curtains allow me to kill the nasty reflections from the glass while still letting the bass energy out? Or would it be best to use regular curtains?
Curtains have unpredictable rates and levels of absorption. We do not use them for that reason. If their density exceeds 5 lbs. / square yard you will have some performance

i produce music in my home studio and my neighbours have been complaining recently due to them staying home due to corona. can some curtains stop some noise from seeping out and disturbing them?
L, It depends on the frequency and amplitude of the noise. Curtains have a certain frequency range that they will work within. If your audio system is a full range system, then they will do nothing for lower frequencies. It will be like holding up a feather to stop a tornado.

Many sounds will have components both below and above 200Hz. For example, your speaking voice probably has a fundamental, loudest frequency that's well below 200Hz. But your voice will also contain many harmonic frequencies at different amplitudes that give your voice its unique sound that people recognize as your voice. If a curtain reduces the magnitude of those upper frequencies, what it will do is change the timbre of your voice, making it a little duller and a little less distinguishable from other voices. Higher frequency components brighten a sound. Even when we speak, these components vary a lot. When you sing the syllable "Ah" or "Oh," the upper frequency components are not as powerful as when you sing the syllable "Eee," and that's why you may notice the latter sounds "brighter." We're stacking sine waves here and varying their amplitudes to create different sounds.
Oh we thought your company was producing sound blankets we would jump at the chance to buy some blankets from your company because in today's music world it's very hard to afford good panels
You will have to build a barrier between yourself (receiver) and the noise source (furnace). Before you build the barrier, you must measure the noise frequency and amplitude.
Acoustic Fields i didn’t understand your response in relation to the context of the comment. is that to say middle and high frequencies are kept in the room also?
