Answer 1

C) to absorb sound

Soft materials such as fabric curtains, carpeting, and padded seats are often used in auditoriums to absorb sound. This helps to reduce echo and reverberation, creating better acoustics for the audience. Absorbing sound also helps to improve speech intelligibility and overall sound quality in the space.
