• B. To decrease loudness.
• C. To control frequency.

Answer 1

The correct option is D To channel sound towards the audience.

In conference halls, the sounds produced reaches to the audience either directly or by bouncing off from the walls and ceiling. When sound waves bounces off a surface, the new direction they travel is related to the angle they strike the surface. Accoustic engineers places a panel on the ceiling and walls to reflect sound directly towards the audience. The curved panels helps channeling the sound waves towards the audience.
