The intensity at which the individual has a hearing impairment if the minimum intensity heard by an individual is 3.4 × 10 − 8 W/m 2 . The formula L = 10 log ( I I 0 ) gives the loudness of sound L based on the intensity of sound I . The value I 0 = 10 − 12 W/m 2 is the minimal threshold for hearing for mid frequency sounds. Hearing impairment is often measured according to the minimal sound level detected by an individual for sounds at various frequencies. For one frequency, the table depicts the level of hearing impairment. Category Loudness ( dB ) Mild 26 ≤ L ≤ 40 Moderate 41 ≤ L ≤ 55 Moderately severe 56 ≤ L ≤ 70 Severe 71 ≤ L ≤ 90 Profound L > 90

Solution Summary: The author calculates the intensity at which the individual has a hearing impairment if the minimum intensity heard by an individual is 3.4times 10-8W/m2.
To calculate: The intensity at which the individual has a hearing impairment if the minimum intensity heard by an individual is 3.4×10−8W/m2. The formula L=10log(II0) gives the loudness of sound L based on the intensity of sound I. The value I0=10−12W/m2 is the minimal threshold for hearing for mid frequency sounds. Hearing impairment is often measured according to the minimal sound level detected by an individual for sounds at various frequencies. For one frequency, the table depicts the level of hearing impairment.
To calculate: The corresponding intensity of sound if the minimum loudness of sound detected by an individual is 30 dB. The formula L=10log(II0) gives the loudness of sound L based on the intensity of sound I. The value I0=10−12W/m2 is the minimal threshold for hearing for mid frequency sounds. Hearing impairment is often measured according to the minimal sound level detected by an individual for sounds at various frequencies. For one frequency, the table depicts the level of hearing impairment.
