Answer 1

Answer #1

The maximum pressure amplitude that the human ear can tolerate in loud sounds is about 28 Pa.

Therefore the maximum pressure variations the human ear can withstand are approximately 30 Pa.

Answer is 30 Pa.

pmax=BkA.

B bulk modulus

k = wave number

A amplitude

The ossicles transmit oscillation to the fluid (mostly water with bulk modulus B= 2.18x109 Pa) in the inner ear
