OK, I don't have much to gain in this but, thought this would be the 'honest' place to ask this question...

How would you go about getting foam tested for its acoustic dampening properties?  Do I hire an acoustic engineer?  Are there any acoustic engineers here that would be willing to help a company create acoustic foam products?

I just started working for a foam-making company and I thought I'd help them make foam products for acoustic purposes.  I really wish I'd known I'd be working here a month ago... since I just finished buying and building everything I needed.

In any case, just trying to get started.  Any help is appreciated.

You could start with a good book:

Master Handbook of Acoustics



It has a chapter about sound adsorption that discusses sound adsorbing materials and measurement techniques.

Does your company make open cell foam?

Thanks for the book... I'm just trying to point THEM in the right direction.  If I work too hard at it, I'll have to charge them.

Yes, they make open-cell foam.

You probably know all this but there is a noise reduction coefficient (nrc) that will rate the average amount of sound absorbed by a material.  If this number reaches 1 it is the most you can get.  NRC is claculated during testing in an acoustical laboratory.

Yes I knew about it but, I just didn't know where to find an acoustical labratory to do the testing.  I'm searching now, though... thanks!  

This company has some good ideas and they're great to work for so, I just wanted to get them moving in the right direction.
