Answer 2

Answer:

The roof and walls of the auditorium or cinema hall are generally covered with sound-absorbent materials like draperies or compressed fibreboard to reduce reverberation. These materials reduce the formation of echoes by absorbing sound waves.

Explanation:

• Any smooth and hard surfaces, such as wood, metal, or glass, reflect sound and amplifies noise, or resonate.
• Therefore, the noise will not be absorbed by surfaces that are rough and not firm.
• Hence, sound-absorbing materials, such as glass wool with fabric on top, draperies, or compressed fibreboard, are used to line the walls of auditoriums.
• The ceiling tiles have sound-absorbing characteristics as well.
• Likewise, the seats are not made of metal and are covered with cloth.
