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 1.93 x 10-4 m2. How much sound energy is incident on the eardrum during this time?© BrainMass Inc. brainmass.com October 10, 2019, 12:21 am ad1c9bdddf
Using the formula of sound intensity level, we can compute for the sound intensity ...
