For the faintest sound that can be heard at 1000 Hz the pressure amplitude is about 2x10^5 N/m2 . Find the corresponding displacement amplitude. Assume that the velocity of sound is 331 m/s and the air density is 1.22 kg/m3 .

Solution:
For the faintest sound that can be heard at 1000 Hz the pressure amplitude is ab
