The actor Ice-T needs to create a special sound effect for his new movie. The sound will create a displacement amplitude of 8.4*10^-6 m and can have an adjustable frequency. For work place safety, Ice-T has limited the maximum pressure amplitude of the sound waves to 10 Pa. In the movie set, the bulk modulus of air is 1.42*10⁵ Pa. What is the highest frequency sound that Ice-T can use without exceeding the limit on pressure amplitude? Do you think that other people on the movie set be able to hear this sound? Keep in mind that the speed of sound in air should be 344 m/s.
