A 54 dB sound wave strikes an eardrum whose area is 4.0 x 10-5 m^2.
(a) How much energy (in watts) is absorbed by the eardrum per second?
(b) At this rate, how long (in years) would it take your eardrum to receive a total energy of 1.0 J?© BrainMass Inc. brainmass.com June 3, 2020, 10:17 pm ad1c9bdddf
(a) The value D of the sound intensity level I is given in decibels by
D = 10 * log (base 10) [I/I_0],
where I_0 = (10^-12) W/(m^2), which is ...
