Special thanks to Dick for sending me not only papers but also useful hints on reviewing the history of BM-models. So far I have the Lumer and Johannesma papers. I would still be very thankful for the following two: D. Schofield, "Visualizations of speech based on a model of the peripheral auditory system," NPL Report DITC 62/85, 1985. J. L. Eriksson and A. Robert, "A simple nonlinear active cochlear model with distributed feedback," Proc. International Symposium on Nonlinear Theory and its Applications (NOLTA), Le Regent, Crans-Montana, Switzerland, 1998. Thank you! Tamas "Richard F.
