I’ve learned more in the last 60 minutes, watching your videos on RUclips, than I’ve been able to glean from the last 10 years of reading and discussions with other Audio hobbyists Thank You !!
Watching your videos helped me understand that I never heard my equipment the way it truly sounded. I have modest budget and modest space but even with this after learning from you I have made listening to music and watching movies in my apartment a lot more fun and enjoyable. Thank you for all your hard work.
im so sorprise after seeing the videos of years before, i thought everything would be different back on 2020, but no, still with the same attitude and vibe, thumbs up, i like the spirit man, its cool learning with you. totally.
Than you for this video. I just moved into an apartment 3 months ago and my neighbor has. Loud television with speakers connected and the sound a vibrating through my thin hard wood floors. Based off of your video- it’s low frequency noise . What can I use DYI ? Is vinyl good under a rug?
Why is home insulation material bad for the panels? I have mine with rockwool now I dont know what to do I dont wanna spend 10k on my room I have roughly 1k
6:40 Concrete frame buildings are the worst in terms of sound transfer (with the exception of plasterboard walls which are just transparent to sound). The fact is that concrete by itself is a good medium for noise and vibration to travel for long distances (quite a few floors or rooms apart) and to make matters worse, in all modern constructions (i.e. anything in this and the last century) concrete is re-enforced, i.e. it has a good amount of construction steel in it which is a great conductor for noise and vibration. So, if you live an a concrete building and someone decides to blast the stereo three floors down, two flats across, there is simply nothing you can do about it: you will get noise, in fact annoying noise because it'll be muddled, so your best bet is to either join the party or go out for a stroll. Potentially - this must be stressed - one could build a suspended sound "insulated" room within the concrete building room where the suspension elements offer dampening that is tuned appropriately so as to limit the transfer of low frequency vibration through the suspension elements. Assuming these elements are, say, steel springs that can take the weight of the suspended room, guess what: higher frequencies will still travel through the spring mass and couple to the suspended room. That gives you an idea of the size of the problem for those living in building blocks. If what you live in is attached directly to the ground however, with a good distance of separation from neighbours, then you have a lot more freedom in tackling the external noise.
You must match the barrier material type, its desnsity, and construction methodology to the frequency and amplitude of the noise in the usages for that building. A concrete building is more oriented towards structure support than noise transmisson.
Subs in larger rooms can be suspended from ceiling away from room boundary surfaces. They can also be elevated off the floor with the proper height platform
Thanks for your well-informed videos! I remember one where you talked about how problems in the mids and highs, for instance with a bright room or piercing upper mids, can actually start with, or come from, low frequency problems. I don't remember the argument - could you point me to it?
Acoustic Fields Thank you. So a mode with a 1st harmonic at 50 Hz would have a 7th harmonic at 3600 Hz and 8th at 7200 Hz, and these would have an audible magnitude? The reason I ask is that some consultants say to start with management overall decay times in mids and highs - and then start to manage lows as much as possible. Would it make more sense to focus on primary modes first to see the effect on their harmonics?
hi dennis I'm currently building your QRD7 plans using only handtools, I plan on putting them on both the back and front wall, I might make more for the side walls as well in time but making one with joinery is very time consuming, also plan on making the bass traps but I am starting with the diffusers, I do use power tools as well but am limited with workshop space, hope to show you the results once they're done.
Great video. I'm new to sound treatment. I have a medium-small sized room: 18'x18'x8'. I think that I made a mistake of ordering 3 diffuser Skyline wooden sculptures panels. Each is 31.5 inches x 17.3 inches by 3 or 4 inches deep. I bought 3 of them. Together, they can easily take up half of the wall directly behind my listening area. Did I waste my money on these? If not, can someone kindly suggest where I can best use them? Thanks!
Diffusion is a technology that has requirements that must be met using absorption first before introducing any diffusion type. Here is a link to those requirements. ruclips.net/video/fB3EsOqYZ6A/видео.html
de floor to piano problem? the piano is made to reflect on the floor! a big part of the piano is the bottom of the piano. What pianist would want that to be absorped?
What’s your thoughts on using acoustic ceiling tiles inside wall absorbing panels instead of rock wool or fiberglass insulation? I’ve heard your views on using rock wool, and also fiberglass, but I don’t recall you mentioning pro or con about acoustic ceiling tiles inside of the absorbing panels.
Sir, In a few of your videos you mention membrane technology, but when I search for it on your channel I can't seem to find any video title specifically mentioning said technology. Did I miss something? Could you dedicate an episode on it? Thank you, greetings.
There are three main types of low-frequency absorption. We have membrane, diaphragmatic, and Helmholtz. Membrane and diaphragmatic work the same. The main difference is that diaphragmatic has more horsepower due to increased cabinet densities.
not sure if you guys gives a damn but if you're bored like me atm you can stream all the new series on Instaflixxer. I've been binge watching with my gf for the last couple of months :)
What is room processing? You are adding or subtracting energy in the time and frequency domain. You are doing this to make the recording fit the room. We know that it is much better to treat a room in the analog domain and use processing to polish the small peaks and dips in response the analog treatment did not get. There is too much over processing today. Everything sounds the same. Music and voice deserve much more respect than that. They are much to important to be reduced to ones and zeros. There is no harmony in ones and zeros.
100 million people smoke cigarettes. Quantity of usage does not dictate quality. This "technology" was used because they did not have any other ways to try and manage low-frequency energy. It was find a deep enough space and fill it with building insulation. That's what everyone did without asking questions. It was all they knew. We represent the next treatment level with our carbon technology. We get better rates and levels and take up 50% less physical space than anything used with building insulation. We can increase the absorption rate by increasing our carbon density so we get much more out of every square foot of space.
Acoustic Fields I'm not saying there is anything wrong with your technology and in fact, it probably IS better, I'll take your word for it. However, it's not practical or available to all. For example, can I even buy it in Australia? How much does it cost? Insulation material is still a great option for those who need to treat a small home studio and it's a hell of a lot better than nothing! My issue is that you are making statements about insulation material that are simply based on assumptions, not fact! You assume it's dangerous with no actual proof that it is. That's not right.
We are an international company with manufacturing facilities in Europe and the states. Our account base shows 15% of our clients are in Australia. You do not have to take my word for the hazards with insulation. Do your own research.

S, Most are hearing only 30% of what their system can produce.
I have been learning more about acousitcs in this channel that on my beginings as a sound tech. Thanks!
Great to hear!

Building insulation does not provide the proper rates and levels of absorption for music and voice. It also has numerous health risks.

Great video and explanation!
Glad it helped!
Would a sub be better on the ceiling on the floor? our church is small more of rectangle and our 2 main speakers are hanged on the ceiling.
Subs in larger rooms can be suspended from ceiling away from room boundary surfaces. They can also be elevated off the floor with the proper height platform

S, Fundamentals and harmonics. Study those two main topics.
Acoustic Fields Thank you. So a mode with a 1st harmonic at 50 Hz would have a 7th harmonic at 3600 Hz and 8th at 7200 Hz, and these would have an audible magnitude?

T, If this is two channel audio do not put diffusers on side walls.
Denis, at what frequency "range" does LF wave become MF rays?? thanks
C, 90 - 100 Hz. is a good start
Great video. I'm new to sound treatment.

@@AcousticFields Thanks Dennis.
I appreciate your videos.
You debunk myths and present your facts clearly & precisely.

Absolutely. This was the impetus behind our platforms.

Acoustic Ceiling tiles do not represent the proper rates and levels of absorption for critical listening rooms.
Awesome video!! 👏🏻👏🏻👏🏻👏🏻
F, Thank you. We all appreciate your support.
Acoustic Fields hello! I am from Brazil and I would like to talk to you. Whats your email adress? Thanks!

hi sir Dennis, is it practical to use diaphragmatic absorber in big rooms like churches? are your products available in the philippines?
If you have unwanted low-frequency pressure in certain areas, then you must use the appropriate technology to absorb the unwanted pressure.
Sir,
In a few of your videos you mention membrane technology, but when I search for it on your channel I can't seem to find any video title specifically mentioning said technology.
Did I miss something? Could you dedicate an episode on it?

@@AcousticFields Ok, thank you.
I still have some questions, so I hope for a dedicated video one day...
Great channel!
Thanks for sharing. When I treat my sidewalls how high should the panels be? Should the midpoint of the panel be at the height of the tweeter?
not sure if you guys gives a damn but if you're bored like me atm you can stream all the new series on Instaflixxer. I've been binge watching with my gf for the last couple of months :)
@Marcel Benicio yea, I've been using instaflixxer for since december myself :)
So what do you use instead of foam? Would be good to say.
C, Treatment types and amounts depend on many variables. You must consider usage, Rt-30 times, volume, and pressure levels used just to name a few.
How good are DSP's at managing these issues?
Can a DSP only really manage issues "well" at a single point in the room?
What is room processing? You are adding or subtracting energy in the time and frequency domain. You are doing this to make the recording fit the room. We know that it is much better to treat a room in the analog domain and use processing to polish the small peaks and dips in response the analog treatment did not get. There is too much over processing today. Everything sounds the same. Music and voice deserve much more respect than that. They are much to important to be reduced to ones and zeros. There is no harmony in ones and zeros.
@@AcousticFields I think I get it now. It is perceived as cheaper and faster to process the sound than make the room work with you. Thank you!
💪💪💪💪💪💚💚👌
Thank you for your support and following
Building insulation clearly does work though.
It has poor rates and levels of absorption for music and voice.
Acoustic Fields yet, it's used successfully every day in studios all over the world!
