How much energy is transferred to her eardrums

Reference no: EM13526650

A fan at a rock concert is 50.0{\rm m} from the stage, and at this point the sound intensity level is 109{\rm dB}. Sound is detected when a sound wave causes the tympanic membrane (the eardrum) to vibrate . Typically, the diameter of this membrane is about 8.40{\rm mm} in humans

Part A How much energy is transferred to her eardrums each second ?

Part B How fast would a 2.00{\rm mg} mosquito have to fly to have this much kinetic energy?
