Problem: Hearing damage may occur when a person is exposed to a sound intensity level of 90.0 dB (relative to the threshold of human hearing) for a period of 9.00 hours. An eardrum has an area of 1.28 x 10-4 m2.
Part A: How much sound energy is incident on the eardrum during this time?
Please use great detail in explaining the solution for above problem. Thank you.
