:Audiogram:

Pronunciation GB: ˈɔːdiəʊɡræm, GA: ˈɑːdioʊɡræm

A graph of a hearer’s ability to detect pure tones at various frequencies, usually in the range 100-8000Hz. The lowest intensity that a hearer can detect at each of the test frequencies is recorded. The responses are plotted relative to a standardised curve for normal hearing. Ideally, a normally hearing subject’s response curve should be a flat line at 0dB. In practice, response levels of 20dB or less are considered normal. Any response of 30dB or above indicates some hearing loss.
