Subject: Cochlear maps.

A useful and often quoted paper by D. D. Greenwood (1990) has the title "A cochlear frequency-position function for several species -- 29 years after". In my opinion, however, four differently defined functions are necessary to adequately describe cochlear physiology. In the term "cochlear map", "map" signifies "mathematical function". Presumably the term "cochlear map" is in common use because "cochlear function" normally designates the way in which the cochlea works. The study of cochlear maps will help to understand cochlear function. A two-page proceedings paper has just appeared: R. Frosch, "Old and New Cochlear Maps", Canadian Acoustics, Vol. 37, No. 3 (2009) 174-175. Reinhart Frosch, Dr. phil. nat., r. PSI and ETH Zurich, Sommerhaldenstr. 5B, CH-5200 Brugg.
