A duplex theory of pitch perception

A duplex theory of pitch perception is a paper written by J.C.R. Licklider,[1] and published during the year 1951.[2] The word duplex has the definition, having two parts, and in the specific context of systems of communication, for example computers, it is known to possess the meaning allowing the transmission of two signals moving simultaneously in contrary directions.[3]

Subject

The paper has as its subject the nature of human pitch perception, and therefore belongs within the general classification of auditory theory.[2]

Licklider is credited with originating a model known as autocorrection (AC model),[4] as a composite element of his formulation of the duplex model, during the year 1951, and later developed during the years 1956, 1959 and 1962.[5]

Licklider references G. Révész and A. Bachem within the first paragraph. Other references on the first page R.M.Fano and L.A. de Rosa, N. Wiener, H. von Helmholtz (resonance-place theory), H. Fletcher (space-time pattern theory), J.C.Steinberg and N.R. French (and others at Bell Telephone Laboratories) and R.K. Potter, G.A. Kopp and Harriet C. Green, and also K.N. Stevens.[2]

The paper ends with a section titled zusammenfassung.[2]

The paper finishes with a section headed Zusammenfassung.[2]

Impact

The duplex model served as a basis for models created at a later time, by; Brown & Puckette (1989), Slaney & Lyon (1990), Meddis & Hewitt (1992), Patterson et al (1995), Meddis & O'Mard (1997), de Cheveigné (1998).[6][7]

Slaney & Lyon constructed a pitch detector to serve as a mimic of the anatomical functioning of the human ear, and the perception of sound by a human. The representation formed by the detector is known as the correlogram, which showed two factors, the spectral content and the time structure of any particular sound transmitted for detection.[7]
