Fans at a heavy metal band concert are subject to tunes at an intensity of 1.5 watt/m2. The density of dry air at 273K is 1.293 g/L and the speed of sound in dry air is 331 m/s.
a.) This sound intensity corresponds to what maximum pressure amplitude?
b.) The ear drum has a surface area of ~52 mm2. How much mass would be stacked on a surface area of this size to match the pressure associated with the 1.5 watt/m2 intensity music?
