|An Audiogram is
which records the hearing response of each ear from 250 Hz to 8,000 Hz, which is
the range most essential for speech perception. Hearing response is
unique for each patient.
In the audiogram, the horizontal axis
shows frequency in Hz. The vertical axis shows hearing loss in decibels
(dB). Normal hearing is the 0 dB level. The degree of handicap is
considered mild at 20 dB, moderate at 40 dB, severe at 60 dB, and
profound at 80 dB.
