Re: Roots of the term "gammatone"


I recounted some of those mis-attributions in http://dicklyon.com/tech/Hearing/APGF_Lyon_1996.pdf
and concluded:

  Aertsen and Johannesma [AJ80] appear to have coined the catchy name;
  referring to the envelope, they said:

    The form m(t) appears both as the integrand in the definition
    of the Gamma function $\Gamma(g)$ and as the density function
    of the Gamma distribution, therefore we propose to use ... the
    term "Gamma-tone" or "$\gamma$-tone."

    ... The non-hyphenated "gammatone," as an adjective modifying
    "filter," appears to be due to Patterson et al. [P88].

Dear List,

I am looking for the first time use of the term "gammatone". Flanagan
('65), Johannesma and de Boer ('72,'75) did not use that term. Patterson
et al. write in their '88 APU report "An efficient auditory filterbank
based on the gammatone function" that "Johannesma (1972) used this
function to summarize revcor data, although he did not refer to it as
the gammatone function, and the function was not fitted to revcor data.
The name appears to have been adopted by de Boer and de Jongh (1978)".
However, I am not able to find the term "gammatone" in the de Boer and
de Jongh paper "On cochlear encoding: Potentialities and limitations of
the reverse-correlation technique" JASA 63(1), 1978.

Any ideas?
