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, they absorb it or the sound waves bounce off.
The natural property of the material has that ability. Alot of objects absorb wound, for example the sides of your stereo are sound insulators. However, not all have the same or even this ability at all. As for soft and rough, they most likely won't play a factor, therefore you should look into the material of objects to possibly determine the insulation of sound.
No they most definitely do not absorb sound
Cotton absorb sound because it has small area that sound penetrate and doesn't reflect .
A rock, a tree and a dog are three opaque objects that stop or absorb light

Not all objects absorb water
yes i hav another qustion for u if a tree falls in the woods and nobody is aroun to hear it does it make a sound answer that on

white objects reflect heat while black objects absorb it
Some surfaces reflect sound well, others don't.
No, concrete does not absorb sound as it very dense.
Objects that do not absorb LIGHT are called opaque. You can't see through these types of objects.
