Question

Why are the roof and the walls of an auditorium covered with sound-absorbing materials?

• A. To reduce echo
• B. To increase loudness
• C. To control frequency

Answer 1

The correct option is D

To reduce multiple reflections.

Reverberations cause sound persistence in the concert halls. So the roof and the walls are covered with sound absorbing materials to avoid multiple reflections.
