Detailed Solution

The above statement is true.
Wool is an animal fibre generally used to make clothes. Wool is used in soundproofing as it is a good absorber of sound. These viscoelastic properties make wool insulation the perfect choice for improving room acoustics and thermal control. The wool has viscous and elastic properties, converting sound energy into heat energy. Hence, it provides perfect thermal insulation and noise dissipation.
