OpenStudy (anonymous):

A sound wave with intensity 1.8×(10^−3) W/m^2 is perceived to be modestly loud. Your eardrum is 6.3 mm in diameter. How much energy will be transferred to your eardrum while listening to this sound for 1.0 min?

OpenStudy (whpalmer4):

Find the area of your eardrum in square meters. Multiply the intensity by the area and the time (in seconds) to get the energy transferred.
