Re: Electronic Paper Request


I have sent you the Johannesma 1972 paper, the origin of the term "gamma-tone".

I may have Schofield 1985 on paper some place, since I quoted from it back in '96; I'll try to find it if someone else doesn't.

I haven't heard of the Lumer 1987 papers before, but they look good, and are available online for money. I might get...

Eriksson & Robert 1998 is just an early version of Robert & Eriksson 1999 JASA, I think. All they say about it is "Previous versions of the model were pre- sented in Eriksson and Robert, 1998." They were among the few people who picked up on my 1996 all-pole gammatone filter idea and used it to make a good model. I'd be interested if you find it.

If you're interested in the history of gammatones, a relevant often-overlooked paper is Dirk Van Compernolle's 1991 IPO report "Development of a Computational Auditory Model". It turns out he did the pole-zero decomposition of the gammatone, and the all-pole version as an approximation, a bit before Slaney did. From the Laplace transforms that he tabulated, he concluded, "From the above table it can be seen that an all-pole filter approximation will be excellent as long as alpha is small, i.e. for sharp filters, which is the case for a cochlear filterbank." It's easy to find online.

Dear List,

I am desperately looking for copies of the following papers:

P. I. M. Johannesma, "The pre-response stimulus ensemble of neurons in the cochlear nucleus," Proc. IPO Symposium on Hearing Theory, B. L. Cardozo, E. de Boer and R. Plomp, eds., Eindhoven, Netherlands, pp. 58-69, 1972.

D. Schofield, "Visualizations of speech based on a model of the peripheral auditory system," NPL Report DITC 62/85, 1985.

G. Lumer, "Computer Model of Cochlear Preprocessing (Steady State Condition) I. Basics and Results for one Sinusoidal Input Signal," Acta Acustica united with Acustica, vol. 62 (4), pp. 282-290, 1987.

G. Lumer, "Computer Model of Cochlear Preprocessing (Steady State Condition) II. Two-tone Suppression," Acta Acustica united with Acustica, vol. 63 (1), pp. 17-25, 1987.

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.

Would anyone be able to help me with these?
