What is the Mel scale and how does it relate to pitch perception?

The mel scale is a scale of pitches judged by listeners to be equal in distance one from another. The reference point between this scale and normal frequency measurement is defined by equating a 1000 Hz tone, 40 dB above the listener’s threshold, with a pitch of 1000 mels.
