Placing the carpet directly on the wall will roughly absorb only the highest frequencies. This includes surfaces such as ceiling solid floors and walls. For a 1 khz frequency place the carpet at 85mm from the wall. They are often used interchangeably but there is a notable difference between them.

They re also water resistant and provide an extra protective layer for your flooring. To do the job place the material at an optimal distance from the wall. Acoustic foam is a soundproofing material that insulates and absorbs sound echoes bouncing over them. Since carpet is an exceptional sound absorber carpet can reduce the sound of walking by 25 to 34 decibels whereas laminate flooring reduces surface sounds by only 1 to 6 decibels.

If the carpet is open backed the type of pile and knap does not matter much as long as the sound can get into the felt underlayment.

In most flat walls sound vibrates easily. Before discussing what s wrong with using carpet the walls for soundproofing let s examine the difference between soundproofing and sound absorption.

If you stick carpet directly to a wall it isn t thick enough to affect more than the very highest frequencies thus throwing your whole room out of balance. At the same time carpet reduces noise in the living space itself as well as noise from neighbours. The best situation would be to find a sound absorbing knap with an open back. The foams work perfectly when installed on walls.

Fiberglass panels are typically a lot denser than foam and therefore absorb sound even better. You will get sound absorption from this felt underlayment. Because of this they tend to cost more than foam panels. Consider it a gift to your neighbours.

4 inch fiberglass panels range all the way down to a low 100hz. 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.
