12 gives the loudness of sound L (in dB) based on the intensity of sound I (in W/m²). The value I = 10 The formula L=10 log 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.
