Assume that the displacement(s) of air is
proportional to the pressure difference ($$\Delta $$p)
created by a sound wave. Displacement (s)
further depends on the speed of sound (v),
density of air ($$\rho $$) and the frequency (f). If
$$\Delta $$p ~ 10 Pa, v ~ 300 m/s, $$\rho $$ ~ 1 kg/m

^{3}and f ~ 1000 Hz, then s will be of the order of (take the multiplicative constant to be 1) :2
