Eva Foam Sound Absorption

The closed cell structure can make the foam have a smooth and flat surface that can help raise its resistance.

Eva foam sound absorption.

As they have many tiny open cell structure this can make them very powerful and effective to take in the lots of external sound or noise. Acoustic and thermal insulation properties. The energy is dissipated as heat. Closed cell foam is a specific type of foam that boasts a higher r value than its open cell counterpart.
