Differentiate reflection and absorption of sound

Open in App

Solution

Reflection of sound
Absorption of sound
1.Sound when it hits the surface of an object and gets reflected is called reflection of sound 1.Removal of sound energy from the sound wave due to the nature of material is called absorption of sound
2.Reflection of sound wave is called echo which is heard by us 2.During absorption of sound ,the kinetic energy of sound is converted into heat energy
3.Materials that act as good reflectors are hard and smooth surfaces viz. concrete, metal ,steel, dense materials. 3.Materials that act as good absorbers are soft ,fluffy, porous, light surfaces viz. asbestos, clothes, curtains, thermocol ,foam
