Which is best used as a sound absorbing material in partition walls ? A. Stone chips B. Steel C. Glass – wool D. Glass pieces

The correct answer is C. Glass wool.

Glass wool is a type of insulation made from molten glass that is spun into fibers. It is an effective sound absorber because it has a high surface area and is made of small, irregular

fibers that trap sound waves. Glass wool is also a good insulator, making it a versatile material for use in partition walls.

Stone chips, steel, and glass pieces are

not as effective as sound absorbers as glass wool. Stone chips are hard and smooth, and they do not have a high surface area. Steel is also hard and smooth, and it is a good conductor of sound. Glass pieces are irregular in shape, but they are not as effective as glass wool at trapping sound waves.

In conclusion, glass wool is the best material to use as a sound absorber in partition walls. It is effective, versatile, and affordable.
