drop a pebble in a glass of water. Notice the same effect, where the water ripples and spreads out in a circle. But notice that when the ripples reach the sides of the glass, they can travel no further. To a certain extent, this is how sound-proofing works.
Sound-proof insulationSound-proof insulation is often made from vinyl/nitrile-blended foams that come in thick padding or an egg-crate shape. The foam is laden with minute air cells. When sound waves hit these air cells, friction occurs and the waves are quickly dissipated, thus significantly reducing decibel levels. The leftover energy created from when the sound waves hit the foam is released as heat (though not something you will particularly notice).
Thus, sound-proof insulation acts as a trap for sound by absorbing the energy (remember the waves in your pool of water) created by noise. When properly installed in the walls of your home and around your heat and water pipes, sound-proof materials will help to reduce the drama of the outside world going on around you.

An insulator for heat and (less so) for electricity. A conductor for sound and vibration.
Rubber is an insulator of sound, as it dampens and absorbs sound waves rather than allowing them to pass through. Rubber is a poor conductor of sound due to its molecular structure, which hinders the transmission of vibrations.
Air is the worst sound insulator as it allows sound waves to pass through easily. Materials like foam, fiberglass, or mass-loaded vinyl are better options for soundproofing.
Cotton fibers are soft, porous, and tightly packed, which allows them to absorb and trap sound waves. This absorption helps reduce the transmission of sound through the material, making cotton a good insulator of sound.
Yes, wool is a good sound insulator because it has natural properties that absorb sound waves and reduce echoes. It is often used in soundproofing applications for its ability to dampen noise.

Yes, rockwool is a good sound insulator due to its dense and fibrous composition that effectively absorbs and dampens sound waves.

a insulator of electricity is a material that insulates, especialy a nonconuctor of sound,heat,or electricity.

An insulator is an object that electricity, heat or sound cannot pass through. It is the opposite to conductor.
