The threshold of hearing is 0dB, but most audio tests will begin at 10 dB, the sound of In normal-hearing ears both curves are placed on the audiogram plot within the range of values that do not exceed 20 dB HL (Fig. 19.6A).
A profound hearing loss is anything greater than 80 decibels. 2020-09-02 An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies.

You won’t see the groupings on the right hand side on most audiograms. The Hearing Test Hidden hearing loss refers specifically to the reduced amplitude of sound-evoked neural responses that occurs with loss of synapses that connect the inner hair cells to the auditory nerve, so the patient’s audiometric difficulties are hidden behind a normal audiogram.
