Styrofoam does absorb sound but it reflects it also. It absorbs more than a brick wall but not as much as softer foams. It does make very good heat insulation.
No they most definitely do not absorb sound
No, concrete does not absorb sound as it very dense.
It may block some sound, but it is rather ineffective as a sound insulator.
reverberants
Cotton absorb sound because it has small area that sound penetrate and doesn't reflect .
it absorbs sound well
no
Usually, stuff that is soft will absorb sound.answ2. Sound is a vibration of air molecules, and anything that may be made to absorb energy from the molecules will absorb sound. If the material has soft fibres, and can allow the sound to penetrate easily, (is porous) then the collision of sound molecules with the fibres, will transfer the energy from the molecules to the inelastic fibres, where it will be dissipated as heat.
No.
nope
no, they absorb it or the sound waves bounce off.
that was weird
