he intensity level produced by a jet airplane at a certain location is 170 dB. (a) Calculate the intensity of the sound wave generated by the jet at the given location. 0.100 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. W/m (b) Compare the answer to part (a) to the threshold of pain and explain why employees directing jet airplanes at airports must wear hearing protection equipment.

A noisy factory machine produces a sound intensity of 1.00 x 10-5 W/m2 when measured 10 m from the machine. Assume that the sound spreads out uniformly into 3 dimensions for this set of questions. What is the sound power output of the machine? (Give your answer in mW.) What is the decibel level of the machine at 10 m? At what distance is the decibel level equal to 55 dB? (Give your answer in m.)

The area of a typical eardrum is approximately 5.0 x 10°m². Calculate the sound power on the eardrum at: (Intensity = Power/Area) a. The threshold of hearing. b. The threshold of pain.

A rock band creates a sound intensity level of 111 dB at a distance of 20.0 m. (a) Calculate the sound intensity. W/m2 (b) Assuming sound from the amplifiers travels as a spherical wave, what average power do the amplifiers generate?
