Question
For Exercise, the formula L = 10 log (£) gives the loudness of sound L (in dB) based on the intensity of sound I (in
W/m2). The value 10 = 10-12 W/m2 is the minimal threshold for hearing for midfrequency sounds. Hearing impairment is
often measured according to the minimal sound level (in dB) detected by an individual for sounds at various frequencies.
For one frequency, the table depicts the level of hearing impairment.

a. If the minimum intensity heard by an individual is 3.4 x 10-8 W/m2, determine if the individual has a hearing
impairment.
b. If the minimum loudness of sound detected by an individual is 30 dB, determine the corresponding intensity of sound.
