Sound Insulation Testing Setup?
Sound Insulation Testing Setup?
(OP)
I'm looking to improve the sound dampening characteristics of a structural panel and would like to build a testing setup to analyze changes made to the panel structure and layering.
The idea is to have a setup that is capable of testing small 12" x 12" sections of paneling.
I'm not really sure where to begin and was hoping I could get a starting point or some design guidelines for an anechoic chamber or test setup that would help me accomplish the above.

After doing a little digging and looking for some testing setups, I was thinking of building a small cube made of the panel material. There would be a sound source inside and a sound measuring device outside. Would this be an acceptable DIY setup? Would it be better to perform such a test within an anechoic chamber?

The idea or goal of these tests is to come up with the optimal material and layering configuration to reduce noise.
There is some baseline data for a current panel. A sample panel using the same configuration would be created to fit the testing rig, and it would be optimized from there. The final full scale product will be sent out to a laboratory for official testing and to gather actual data.

RE: Sound Insulation Testing Setup?
My point is, for assessment of design changes it is usually faster (and cheeper) to play around with a numerical model than building and testing various physical models. Then, after narrowing in on the best configurations, you can build and test one or more for real-world/lab data.
