Help with my theatre, physics cwrk!?

Question

Hi, im doing my physics coursework revisit and i really need to to know how hard and soft surfaces can be used in a theatre.

Hard surfaces on the walls can be used to reflect sound right?
but what about soft surfaces?

Answer 1

Absorb sound.
Absorb light.
Comfortable seating.
Flexible curtains.
Flexible backdrops and stage sets.
More organic (soft) lines for decorations.

Answer 2

When a sound wave is incident on any surface, a part of the incident energy is absorbed. Different substances absorb sound energy to different levels both in hard and soft surfaces. The remaining energy is generally reflected. Thick screens or curtains, mats, carpets, wood, card boards, are some of the examples for the sound absorbers. Open windows and doors are good absorbers because the sound energy is transmitted through them completely. The amount of sound abosrbed by a material can be determined by comparing it with an open window of the same area..

Answer 3

Soft surfaces to help deaden sound, create texture for visuals....that kind of thing.

Hard surfaces....same thing. You want to mix these surfaces for all things 'touched' by people tho. Always with safety in mind tho. You don't want smooth, hard surfaces on a floor at an entrance say....possibliity of someone slipping. But you may want soft surfaces on corners, hand-rails (rigid of course, but a soft cover).

Get the idea?

Answer 4

Soft surfaces absorb sound.
