The tympanic membrane, also known as the eardrum, is a thin membrane within the ear, that vibrates when subjected to sound waves, and is ultimately responsible for our hearing. A man's tympanic membrane has an area of 4.8 x 10-5 m2. For how many years would this man have to listen to music of sound intensity level 61.3 dB, before his eardrum would receive a total of just 1 Joule of sound energy? Assume the membrane is perpendicular to the sound wave velocity, and assume a year has exactly 365 days.
