Which of the following materials would be the least efficient in soundproofing a room: clay tile, plaster, or perforated acoustic ceiling material? Be sure to use your knowledge of the coefficient of absorption in your explanation.

Respuesta :

Answer: Clay tile

Explanation: Clay tile would be the least efficient because it has the lowest coefficient of absorption (3%). This means that percentage of the

energy in an incident wave that remains in a reflected wave is

equal to 97% and is very high. (Remember that this is equal to

100 minus the coefficient of absorption). Very little of the sound energy would be absorbed.
