Determine how much energy is absorbed by the eardrum

Reference no: EM13556273

A 48dB sound wave strikes an eardrum whose area is 4.2×10?5m^2.

A.) How much energy is absorbed by the eardrum per second? (P= ? W)

B.) At this rate, how long would it take your eardrum to receive a total energy of 3.8J ? ( t=? years)
