Three characteristics of a medium required for propagation of sound are as follows:-

• The medium must be elastic so that its particles come back to their initial position after displacement on either side.

• The medium must have inertia so that its particles may store mechanical energy.

• The medium should be frictionless so that there is no loss of energy in propagation of sound through it.
