History of canal distortion products

- Zwicker (1955).

*Cancles DP using a third tone in the canal

	stimulation: the idiophonic effect'' Acta Otolarynol. 43, 396-415
-Ward, W.D. (1955). ``Tonal monaural displacusis'' JASA 27 365-372
-Goldstein (1967) Auditory nonlinearity

*Uses a tone in the canal to cancel DPs
-Smoorenburg (1972). Combination tones and their origin.

*Argues that dp must exist on BM from psychophysical data
-Hall (1972)

*cancels DPs in the canal with a third tone
-Rhode (1971) first reports NL on basilar membrane.
-Hubbard and Geisler (1972) NL model of the cochlea
-Rhode and Robles (1974) more NL BM studies
-Hall (1974). Two-tone distortion product NL model of the BM

*Shows propagated DP motion in NL model.
-Kim and Molnar (1975). ``Cochlear Mechanics: Measurements and
	Models'' The nervous system. Tower Editor; Raven Press 1975.

*First to show propagated 2f1-f2 distortion product on the bm
	using population study.
-Wilson (1977)
-Matthews, Cox, Kim, Molnar (1979). JASA paper.

*Disscussion of Acoustic DP's in the canal.
-Kemp (1978) JASA 64, 1386-91
-Kemp (1978) Munster meeting
-Kemp (1979) Arch Oto Rhino Laryngol.

* first acoustic 2f1-f2 observations
-Kim (1980). HR 
-Kim, Molnar, Matthews (1980). JASA
	*Ear-canal sound pressure data

-Mountain, D.C. (1980) Science 210, 71-72
*First shows that stimulating the COCB changes the magnitude of
the DP f2-f1 in the ear canal pressure.

-Siegel, Kim (1982) HR 6 171-82
	``Efferent neural control of cochlear mechanics? Olivocochlear
	bundle stimulation affects cochlear biomechanical nonlinearity''
	Shows effects of COCB stimulation on earcanal Acoustic distortion
	products. First to show it for 2f1-f2.
