Bark scale

The Bark scale is a psychoacoustical scale proposed by Eberhard Zwicker in 1961. It is named after Heinrich Barkhausen, who proposed the first subjective measurements of loudness.^[1] One definition of the term is "a frequency scale on which equal distances correspond with perceptually equal distances. Above about 500 Hz this scale is more or less equal to a logarithmic frequency axis. Below 500 Hz the Bark scale becomes more and more linear."^[2]

The scale ranges from 1 to 24 and corresponds to the first 24 critical bands of hearing.^[3]

It is related to, but somewhat less popular than^{[citation needed]}, the mel scale, a perceptual scale of pitches judged by listeners to be equal in distance from one another.
