Workers around jet aircrafts typically wear protective devices over their ears, as the sound level of a jet airplane engine is typically around 140 dB at 30 m. The average human ear is assumed to be circular, and has an effective radius of 2.2 cm. Considering, what would be the power intercepted by an unprotected ear from a jet airplane engine? PLEASE SHOW ALL WORK AND UNITS.

Do the following on paper, scan or photograph your work, and submit it. You have a room that is 4 m long, 7 m wide, and has a ceiling height of 3 m. The floor is hardwood, = .15 at 500 Hz. The walls are gypsum wallboard (GWB), = .30 at 500 Hz. The ceiling is acoustic ceiling tile (ACT), = .95 at 500 Hz. What is the mean free path in this room?
We will assume that a sound wave, once generated and emitted, will propagate uniformly in all directions of 3-dimensional space. Find an expression for the displacement s(r, t) of the air particles from equilibrium, where r is the radial distance from the source, and t is time. Introduce physical constants/coefficients, with appropriate physical dimensions, when necessary.

A rock band playing an outdoor concert produces sound at 120 dB 6.00 m away from their single working loudspeaker. What is the power of this speaker, in Watts? (Hint: What is the sound intensity at this location?) Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
