freqency absorption per material/product per frequency

[pootle roche]

Hello again,
Just wondering if any one had ever set up a spreadsheet or something similar that keeps track of materials/products in terms of their sound absorption qualities so that builders are able to quickly make comparisons between two or more products in order to select the best solution for a particular purpose within a project.

Nice one, thanks a lot.
Thats really helpful.
Will help me to work out what options I have available.
I prefer to go for max absorption approach even over cost (to a degree),
as the small isolation booth / studio is to be built in a residental area that is in close proximity to loads of neighbors who unfortunately are mostly really noisy a holes (ugly noisy woman!).
This I call the "a hole" proximity effect...
So, i plan to work out a design that will give me the most isolation possible.
And if things get really bad, I can always sleep in the isolation booth.

And, as I am not super wealthy (while I wait for my ship to come in),
I plan to design the project and then fit the project stage by stage,
as I have the money to buy materials.

So, in time, I will get happier and happier.

I guess I will start with soundproofing windows, floors, ceilings and doors.

Then move onto the walls, giving 2 of the walls treatment.

Next, the inner room of the room within a room for the isolation booth.

And finally, the last two walls that enclose the inner room.

With perhaps, acoustic tiles to make the isolation booth look nice and trendy (plus bass traps) to get rid of some of the problem frequencies.

I have just started my journey in studio design, so I do not know much but the basic.
So, anybody have some ace top tips for a studio design / isolation booth that requires max soundproofing/isolation in a very noisy resedintial area, please go ahead and offer me advise.

Especially regarding the best materials to use.
Thanks

I was wondering if any one had access to data on materials not usually used for studio construction.
As, Perhaps there are some materials out there that people haven't thought about using may be worth considering? or even better.
.
If we can evaluate each material for its strengths and weaknesses, then match several materials together in order to create a winning combination for a specific objective.
For example: to absorb all freq content equally for a given spl.
.
Also.
A combination could be engineered to create a compound that reflected only a specific range of frequencies in order to create a specific reflection/absopsion/transmission effect.
I guess this type of science could be used to tailor rooms for specific purposes. I.E. a room ideal for recording full sounding guitars or a room that is good for vocals (generally).
.
This type of science would be similar in nature to that of microphone design.
Tailoring the frequency range to create a reaction for a specific purpose.
.
Maybe there are books that contain the data.
Thanks for any help.
.
Cheers

The link John provided is actually a list compiled by Bob Golds (http://www.bobgolds.com/)
Check his site, it's good stuff.

Hey, Thanks very much.
His site looks really interesting and very relavent for my situation.
Going to have to get handy with the diy I think.
Or draft a mate in who is.
Otherwise I am going to end up with a crooked wonky sieve for a studio.
Which will probably collapse on me during recording.
Thanks again.

i also like the pictures of his dirty pots and pans.
Hey, he's very enthusiastic!
Thanks though as great help.
Especially for people like me who are in the planning stage.
Cheers
