    B Log relationship between thickness of material and sound absorbed?

    So I have done an experiment on the amount of sound energy absorbed based on thickness of pvc foam, and found a logarithmic relationship between the two. I've used the frequency-dependent acoustic attenuation power law, which is derived from stokes' law. Frequency-dependent acoustic attenuation...

    Sound absorption/Acoustuic attenuation coefficeint (α(ω)) of PVC foam?

    I am currently doing a physics experiment to find the frequency-dependent attenuation coefficient (α(ω) )of pvc foam, are there any verified/reliable sources that show the attenuation coefficient α(ω) of pvc foam or materials in general? Best I found is this...
