Problem 3E

Unless indicated otherwise, assume the speed of sound in air to be v = 344 m/s. Consider a sound wave in air that has displacement amplitude 0.0200 mm. Calculate the pressure amplitude for frequencies of (a) 150 Hz; (b) 1500 Hz; (c) 15,000 Hz. In each case compare the result to the pain threshold, which is 30 Pa.

Step-by-Step Solution:

Solution to 3E Step 1 The pressure- displacement relation is given by, p max= 2fvA =density of air=1.225kg/m -3 f =frequency v =velocity=344m/s A=displacement amplitude
