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.

No it is a good sound conductor.
insulator
Styrofoam is excellent
No because water is a good conductor of heat in comparison to wool.
Yes it is a good insulator
Rubber is an object that is a good insulator.
No, sound travels well in water.
Because it absorbs the sound but not all of the sound. :)
It is not. It is a conductor of sound because it absorbs the sound.

insulator
A material that insulates, especially a nonconductor of sound, heat, or electricity. A device that insulates another material or space from something. For instance glass is a good insulator from electricity. The electrons will not flow through glass. Cork is a good insulator from sound. Sound waves have a hard time passing through cork. Wood is a good insulator from heat.
no i think i am right ( i hope )
Cloth would act as a shock absorber and so it vibrates swallowing the sound energy and so energy cannot be passed through. Hence considered as a good insulator
yes water is a good conductor
insulator.
Pure water is an insulator, but in the "real world", water usually has impurities - notably ions - that actually make it a good conductor. This is theory; I don't think it is practical to use water as an insulator.
