    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?

    (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 ...
