Question

A loud factory machine produces sound having a displacement amplitude in air of 1.00 mum. but the frequency of this sound can be adjusted. In order to prevent ear damage to the workers, the maximum pressure amplitude of the sound waves is limited to 10.0 Pa Under the conditions of this factory, the bulk modulus of air is 1.29 x 10^5 Pa. The speed of sound in air is 344 m/s. What is the highest-frequency sound to which this machine can be adjusted without exceeding the prescribed limit? Is this frequency audible to the workers?

Explanation / Answer

yes

it is audible since
