It is usually more convenient to describe a sound wave in terms of pressure wave as compared to displacement wave because –
(1) Two waves of same intensity but different frequencies have different displacement amplitude but same pressure amplitude
(2) The human ear responds to the change in pressure and not to the displacement wave.
(3) The electronic detector (microphone) does respond to the change in pressure but not to the displacement.
(4) None of the above
