REFLECTION OF SOUND

A free sound wave travelling through air strikes a uniform, large, solid, plane surface and gets reflected in the same manner as a light ray. The following facts in connection with reflection of sound are to be noted:

  1. The analysis of reflection from curved surfaces may be derived by applying the laws of reflection of light.
  2. A concave surface leads to the concentration of reflected waves at certain points. Hence concave surfaces maybe provided to work as reflectors.
  3. A convex surface tends to spread the reflected waves. Hence, convex surfaces may be used with advantage to spread the sound throughout the room.
  4. The study of laws of reflection of sound helps in selecting the proper shape of the room with regard to distribution ...
