Sound is detected when a sound wave causes the eardrum to vibrate. Typically, the diameter of the eardrum is about 8.4 mm in humans. When someone speaks to you in a normal tone of voice, the sound intensity at your ear is approximately 1.0 x 10^-6 W/m^2
Question: How much energy is delivered to your eardrum each second?
given that the speed of sound in the air is 343 ms and that human ears are typically 20 cm apart what is the maximum
