Air has a higher specific heat capacity (at 1.0035 J/(g*K)) than concrete (.880 J/(g*K)).Specific heat capacity is the measure of the heat energy required to increase the temperature of a unit quantity of a substance by unit degree (Wikipedia). Because air requires more joules of energy per gram to raise it one degree Kelvin than concrete does, it is therefore a better insulator.

Concrete is not a good insulator as it has high thermal conductivity, meaning it can transfer heat easily. This is why concrete is used in buildings to store heat rather than insulate against it.

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.
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.
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.
Concrete is a poor conductor of electricity, so it is considered an insulator. Electricity does not flow easily through concrete due to its high resistance.
Cotton wool is a good insulator of sound because it is lightweight, porous, and fibrous, which allow it to trap and absorb sound waves effectively. This helps to reduce the vibrations of sound as it passes through the material, thereby reducing the amount of noise that can pass through.
Cloth is a good insulator for sound due to its fibrous and porous nature, which helps absorb and dampen sound waves. The textile material of cloth also disperses sound energy as it passes through, reducing the transmission of sound. Additionally, the density and thickness of cloth can further enhance its sound insulation properties.
A carpet is a good sound insulator because its fibers absorb sound waves, reducing echoes and minimizing sound transmission through floors. The thick material of a carpet also helps to dampen vibrations and block airborne noise, creating a quieter environment.
Polystyrene is neither sufficiently porous nor of sufficient mass to be either a good Sound Absorber, or a Sound Barrier. [Those are the proper technical terms.]
