No, concrete does not absorb sound as it very dense.
Part of the energy of a sound wave is absorbed when it comes in contact with a surface, and the rest of that energy is reflected. A soft surface (such as carpet) will absorb much more of the sound than a hard surface (concrete), but the hard surface would still absorb some amount of energy.
The fibres in a sponge move and trap/absorbthe sound instead of letting the sound travel to another place, that is a very simplified version.
yes it is true that bones can sbsorb more force without breaking concrete can
If the color on the background is darker it is more likely to absorb the heat. If it is lighter it repels the light or absorbs less. Also, concrete slabs, brick walls and tile floors absorb the heat. Ever notice when you are walking on the sidewalk in the summer with no shoes its always burning hot?
A vacuum is a great sound insulator. Materials that absorb energy such as wool are good insulators as well. I heard of a silicone adhesive that transformed acoustic energies into heat - that was a good insulator if it was used to glue two sheets of something together.
Because there is nothing to 'absorb' the sound, echo's are basically a sound reflected by it hitting a surface, if you walked into a house with nothing in it, just the walls, floorboards or concrete floor and ceilings then the sound echos because there are no soft things or cushiony things to absorb the sound and stop it reflecting.
No they most definitely do not absorb sound
reverberants
Cotton absorb sound because it has small area that sound penetrate and doesn't reflect .
Curtains help absorb sound waves, whereas sound waves bounce off solid walls, so a curtained room will be more quiet.

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.
