A 57-dB sound wave strikes an eardrum whose area is 5.0x10-5m^2. The intensity of the reference level required to determine the sound level is 1.0x10-12W/m^2. 1yr=3.156-107s How much energy is absorbed by the eardrum per second? At this rate, how long would it take the eardrum to receive a total energy of 1.0 J?
