Zwicker tone

A Zwicker tone is a short-term auditory illusion which resembles tinnitus (ringing of the ears). It was discovered in 1964 by Eberhard Zwicker at Bell Labs.[1] The Zwicker tone can be described as follows: if sounds with a spectral gap are switched off, a faint tone lasting for several seconds can be heard. Its pitch strength corresponds to the pitch strength of a pure tone of same pitch and sensation level.[2]
