Hi,
thie post is a add on in my recent one.
I would like to get a better understanding of what it takes to reduce the energy of low frequencies.
I would expect that the solutions you offer are the best solution for solving the problem without taking to much space.

Now is there a material that does reduce the energy of LF if it has enough depth for the wavelength to enter it?

U, You would need a depth of 11′ to absorb 100% of a 100 Hz. wave.

Increasing the thickness of Studio Pro acoustic foam as well as adding an air gap between the foam and the wall will lower the frequency of absorption as well as increase the percentage of absorption . Although the thickness of the foam required for 60 Hz absorption will be quite a few feet thick and not very practical. If you need low frequency absorption you’ll need to use a carbon based product.
