I swear I’ve moved my system around 10 times since the quarantine. I hate being handicapped by small rooms but I have no choice where I live. Helpful videos!
Thanks for another great video. I’m having a serious issue with 135hz which peaks like crazy, i guess around + 6/8 db or even more which makes it so hard even to listen to music, not talking about making music. I have no idea how to approach that one.
Pressure and reflections are the two main issues. Pressure is a low frequency issue and reflections are middle and high frequency issues. We use absorption for low frequencies and both absorption and diffusion for middle and high frequencies. Diffusion is not a low frequency managemenht tool.
Descobriu uma resposta? No cômodo onde eu gravo eu percebo que tem uma ressonância super forte na nota Sol em mais de uma oitava (49Hz, 98Hz e 196Hz), e isso tá me deixando maluco já que não consigo gravar um som limpo do meu instrumento (baixo acústico).
Hello, you draw 100 cycle sine wave and said 13 dB and 16 dB. at 30 Cycle. I dont understand how you present 30 cycle sine wave at 16 dB amplitude on that same graph?? Could you plz explain what u did there? Thanks
Simple solutions produce low resolution sound quality. Our mission statement is to produce the highest resolution possible by treating all issues above and below 60 Hz.
G, dB or sound pressure is one factor within rooms. We have reflections which contribute to reverberation times. Pressure and reflections are the two main acoustic categories we must deal with in rooms.
Now that we know what treatment is most likely required (axial low frequency), I'd like to know how to determine on which axis you need that treatment.
so what you saying, if i ever decide to build new house, i should focus on rectangular rooms since building square room is waste of time because you gonna reduce its space with treatment to rectangular anyway?
S, Rectangular rooms have issues that are predictable and consistent which makes treatment management much easier. Square rooms produce coincidental modes which require more treatment especially for low frequencies.
What if you build a pentagonal room? Make it elongated relative to one of the sides. Why not place the ceiling relative to the floor is also not parallel? What happens to mods without parallel surfaces? Can such forms significantly improve the acoustics of the room at equally volumes?
Hey Dennis, the only space I have for a theater room is in the basement with a 7’4” open joist ceiling height and a 10’ width with a variable length up to 25’. Looking to do an atmos in ceiling speaker setup. Is it doable?
You must use a rectangular space for your usage. An L shaped room will not produce predicatable and consisten modal patterns. Take the rectangle and measure inside of it. Place the opening to the rear of the room during measurement process..
@@AcousticFields thank alot for your reply but can you explain me how to place that opening to the measurements ? ,considering it’s not just an opening it is large enough as if it’s another room, same width both rectangles and almost same length
As hobbyist I have 12' × 14' × 8' high room . I don't think I will able to afford your product, however what can I do to my room . I use Dynaudio about 100 watts . Also I'm not a loud listener also I help friends. Thx .
In theory couldn’t you have an active noise cancelation subwoofer setup to not completely kill but at least damp the unwanted low frequency peaks? Might be whole lot simpler than passive damping/absorption/diffusion. Pretty sure it exists in high end vehicles these days.
D, Yes and no. You can reduce amplitude or strength of certain frequencies and even certain octave bands. Making the energy source fit the room requires signal processing which has its own set of issues. Treating the room as best you can for low-frequency energy produces a different sound quality. Its more organic and life like.
The most ignorant question. But if you treat the sidewalls for low frequency issues, how does that affect you in the listening position if you are 6 feet away from the sidewall? How does that impact the listener when you were not near the sidewall?
Thank you for getting back to me. I asked you because I knew you would give it to me straight. You saved me money but more importantly a lot of disappointment.
D, If people could understand the room response curve like I do, if they could test existing technologies and then test and use their own technology since others fall so short on performance and do this for 14 years, they would understand what minimums are required when it comes to treatment specifications. There is no one size fits all usages. Some companies products you can fill your whole room with their "bass traps" and you will still have a "bass issue". It really won't matter though since there is no place to sit in the room.
Problem is when you live in NY and the typical home costs $400+ per square foot. To buy a home with a room big enough to get decent quality sound for a home theater, you have to be a multi millionaire.
@@AcousticFields 100%. Small rooms suck, especially basements with 7 foot ceilings (99% of basements on Long Island). Did the best I could with what I have, but I still long for a nice big room. One day, when I move out of NY
Damn...how many times Denis have to make another video about room size, usage, modes....Ppl don't get the message. I bet you next time all we gonna get its a 5 seconds video redirecting us to another usage, room modes and size video 😂. Now the fk up part is that ppl that makes 20 million questions about the same thing over and over again ....they always end up getting a pack of sound absorbers from guitar center and doing whatever they think its better NOT for the sound...for the looks of the room. 🤦🏽♂️FACTS
I swear I’ve moved my system around 10 times since the quarantine. I hate being handicapped by small rooms but I have no choice where I live. Helpful videos!
J, You can't hide from low-frequency issues in small rooms. You must treat at least two parallel walls as a start.
One of the best videos on the subject. Thanks!
Glad it was helpful!
Thank you denis, your videos helped us a lot
V, Thank you.
So Glad I have been listening to each Video !
Thank you for your support.
Damn i would say, “watch all my videos and THEN msg me for a question” lol. You cover everything
The best videos Dennis.....always educational and most enjoyable mate.

Thanks so much for the videos, super helpful and very clearly explained.
Great information as always. Greetings from Holland.
Keep explaining it, I'll get it one of these days haha!
Pressure and reflections are the two main issues. Pressure is a low frequency issue and reflections are middle and high frequency issues. We use absorption for low frequencies and both absorption and diffusion for middle and high frequencies. Diffusion is not a low frequency managemenht tool.
I do have an strong node issue from 58-60hz on my ceiling.
Trying to figure out how to proceed.The other problem is that I live in Brazil....

All rooms have peaks and valleys in their response curves.
this all depends on the lowest speaker frequenties used in the room...At 60Hz, simple solutions are available.
Simple solutions produce low resolution sound quality. Our mission statement is to produce the highest resolution possible by treating all issues above and below 60 Hz.
@@AcousticFields Yes, but is it required if you have speakers going only down to 60 Hz?
A lot of people are sleeping on this guy, so much info (sometimes it overlap) but still, great stuff
Acoustic treatment in room is based on in how much dB we perate in room
Or
Sound is depend on Acoustic treatment done in room.
G, dB or sound pressure is one factor within rooms. We have reflections which contribute to reverberation times. Pressure and reflections are the two main acoustic categories we must deal with in rooms.
Thanks Dennis! You’re the 1👏🏻👏🏻
A, Thanks. We all appreciate your support.
This definitely helps,..well illustrated,,thank you.
A, Thank you for your support.
Now that we know what treatment is most likely required (axial low frequency), I'd like to know how to determine on which axis you need that treatment.
T, It depends on room size and usage.
Acoustic Fields
My room is 11’x11’ w/ an 8’ cieling and I want to use it for mixing.
I just assumed I’d need treatment on each axis.
so what you saying, if i ever decide to build new house, i should focus on rectangular rooms since building square room is waste of time because you gonna reduce its space with treatment to rectangular anyway?
S, Rectangular rooms have issues that are predictable and consistent which makes treatment management much easier. Square rooms produce coincidental modes which require more treatment especially for low frequencies.

You're a f****** legend!

Hello, how can i calculate L shape room mode ?
You must use a rectangular space for your usage. An L shaped room will not produce predicatable and consisten modal patterns. Take the rectangle and measure inside of it. Place the opening to the rear of the room during measurement process..

Is Safe and Sound considerd to be "Foam"
Building insulation is not a foam technology. Foam is for sound absorption. Building insulation is for BTU retention.

In which frequency of sound we operate in dance floor
G, It depends on the source of noise. Is it a PA system? Is it a live band? Always look at the source of sound or noise as your start.
The most ignorant question. But if you treat the sidewalls for low frequency issues, how does that affect you in the listening position if you are 6 feet away from the sidewall? How does that impact the listener when you were not near the sidewall?
S, Reducing sidewall unwanted pressure issues improves room response regardless of location.
And where we put the those acoustics panel in the room?
P, It depends on the room size and usage.
I gave the thumb 666, I think that must mean that I thought that this clip was "Hellish Good". *LOL*
