Isowall - wall damping

[Boes]

Hi,

Does anyone have any experience or Isowall wall damping or any similar? After watching

it seems to make more sense to damp the walls instead of stuffing a room full of room treatment. For my new house I was wonder if it's worth the effort to do something like this.

The house would be a standard wooden frame structure with a large room combining open kitchen, dining and living room.
The exact dimensions are not finalized yet but it would be a rectangular room 36 feet long, 17 feet wide, 10 feet high.

Look forward to hearing your experience / feedback.

For the front wall I was already considering to get something like:

For the front wall I was already considering to get something like:

The thickness of both diffusers and absorbers is crucial, as it significantly impacts their performance. Well-designed speakers exhibit a linear sound power behavior starting from 100Hz and upwards, and absorbers can potentially compromise their sound quality. This is because absorbers often lack a sufficiently linear absorption behavior that matches the linearity of such speakers.

In short, either get AT LEAST 20cm thick absorbers or diffusers or do not get anything at all. The absorption behavior of absorbers should be as linear as possible starting from 100hz up to 20khz. Same goes for diffusers but from 500hz to 20000hz.

Using those thin diffusers that the youtuber is using can actually mess up the sound, especially when placing diffusers on the front walls. It's honestly a silly idea. First they are placed in the wrong area, second they are too thin. Sure, his room might look fancier than mine which have lots of treatments, but we're here to talk about audio in an audio science review, not interior design.

In comparison this is how a decent diffuser looks like:

Not a silly idea if you have enough absorption material behind the scatter slots. And I would think the front would be a great place for this type of "treatment" to combat the above 100Hz SBIR.

I was mostly referring to the diffusers youtuber has used. Yeah I also use diffusion + absorption combo on front wall.

I don't have any experience...

Are you working with an architect? He/she probably knows something about acoustics, but more importantly they should know how to get in touch with an acoustical architect who you can consult with.

Beyond soundproofing and bass trapping which are "always good" different people have different "tastes" in room sound. So you should know what you're looking for... Some people a highly-absorbent space (like a recording/mixing studio). Othe people like some reflection (generally diffused reflection). Somebody called Ethan Winer a "studiophile". His company sells bass traps and other absorbing panels and I guess he advocates for a "dead" studio-like sound.

And when you're done, of course you should measure the room.... And you probably won't really be done and you may need some more tweaks...

Fully agree with your comments. It would be the intention to put a very thick layer of at least 20cm of absorbing material behind those wooden slats, which are only there to put in front of the cloth.

In a large room like that I would worry about treatment to get your rt60 down and just use absorbers of the right thickness behind the speakers for sbir. Diffusers depend on the room and may not be needed in such a large room.

Same goes for diffusers but from 500hz to 20000hz.

They don't work that high. Beyond a few kHz the wells have to be tiny. The only product I know that attempts that seriously is the RPG Diffractal, and even then it's very uneven.
