Tamas,

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.
