Hearing curve
WebTHE AUDIOGRAM recorded in instances of monaural deafness when the receiver is placed at the deaf ear is called the "shadow curve." Apparent hearing with the deaf ear is called "shadow hearing." It seems that the phenomenon of shadow hearing was known to pioneers of otology and in the era preceding the invention of the audiometer.

The ITU-R 468 noise weighting curve, originally proposed in CCIR recommendation 468, but later adopted by numerous standards bodies (IEC, BSI, JIS, ITU) was based on the research, and incorporates a special Quasi-peak detector to account for our reduced sensitivity to short bursts and clicks.
