Calculative questlon: 15.You and you team are asked to determine the hearing safety parameters for a loud experiment. Since the sound will persist for only a short time, the allowed intensity level that will not result in permanent hearing damage is 135 dB. The experiment consists of a single source with power output of 550 W that projects sound isotropically (1.e., uniformly in all directions) a) At what distance should you set the safety perimeter (1.e., the radius of a sphere in meters) centered at the source? b) Where should you set the perimeter is the power of the source doubles?

Party hearing. As the number of people at a party increases, you must raise your voice for a listener to hear you against the background noise of the other partygoers. However, once you reach the level of yelling, the only way you can be heard is if you move closer to your listener, into the listener's "personal space." Model the situation by replacing you with an isotropic point source of fixed power Pand replacing your listener with a point that absorbs part of your sound waves. These points are initially separated by r = 1.10 m. If the background noise increases by Aß = 4.50 dB, the sound level at your listener must also increase. What separation rț is then required?

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.
