Carpet foam sound absorption. They are often used interchangeably but there is a notable difference between them. This includes surfaces such as ceiling solid floors and walls. Because of this they tend to cost more than foam panels.

Some sound approaches at an angle and so encounters a greater effective thickness of absorber which means that in real life an absorber of this type might be useful down to 300hz or below.

Acoustic foam is a soundproofing material that insulates and absorbs sound echoes bouncing over them.

You will get sound absorption from this felt underlayment. Before discussing what s wrong with using carpet the walls for soundproofing let s examine the difference between soundproofing and sound absorption. Placing the carpet directly on the wall will roughly absorb only the highest frequencies. To do the job place the material at an optimal distance from the wall.
