Origin: Formed within English, by clipping or shortening. Etymon: melody n.

Etymology: Shortened < melody n. (see quot. 1937).

Acoustics.

A unit of subjective pitch, on a scale that is proportional to the pitch of a sound, the pitch of a note of frequency 1000 Hz being equal to 1000 mels (see quot. 1974).

1937 S. S. Stevens et al. in Jrnl. Acoustical Soc. Amer. 8 188/1 The numbers on the pitch scale are related to each other as the subjective magnitudes of the pitches. A pitch of 1000 units (mels) is subjectively twice as high as a pitch of 500 units. [Note] The name mel was chosen as a name for the subjective pitch unit. It was taken from the root of the word melody.

1957 J. L. Hunter Acoustics viii. 249 A tone having an apparent pitch twice as high has a pitch of 2,000 mels..regardless of its frequency.

1962 P. Ladefoged Elem. Acoustic Phonetics vi. 79 Frequency data about speech sounds are often converted into mel units before being presented graphically.

1974 V. B. Mountcastle et al. Med. Physiol. (ed. 13) I. xiii. 417/2 The unit of the scale is the mel, and a value of 1,000 mels is assigned to the pitch of a 1,000 Hz tone sounded at 40 db above threshold for normal observers.
