Question

Name three good reflecter of sound and three good absorber of sound?

Answer 1

Materials that are good reflectors of sound include:

Polished wood,Bricks Glass,Smooth surfaces

Hard objects are the good reflectors of sound because particles bounce straight off them. If they are smooth, the sound reflects at the same angle it hit the surface and is not spread out.

Porous absorbers are most effective when dealing with mid-range frequencies. Typical examples are different textiles, carpets, curtains, open-cell foams, mineral wool insulation, glass fiber, etc. As you'll see, most of our examples of sound absorbing materials also belong to this type.

Answer 2

Answer:

Polished Wood, Carpets, Curtains, clothes, bodies of living organisms and glass

Explanation:

They are bad reflectors of sound but absorb sound better and in fact soft surfaces are better absorbers of sound whereas hard surfaces are reflectors of sound.

Three good reflectors of sound are

1. Walls of a room

2. Polished metal sheets

3. Asbectors
