Dear All,

A while ago I posted a question asking about studies on the masking patterns
and excitation patterns of non-static tones. Thanks to all who replied.
If anyone thinks of any more references while reading this please send them
to me. This is a summary of the replies I received.

Here are interesting references which I found while I was reading around
on the subject:

D.G. Sinex and C.D. Geisler, (1981) "Auditory nerve-fiber responses to
frequency-modulated tones" Hearing Res. 4, 127-148.

R.S. Tyler, E.J. Wood and M Fernandes (1983) "Frequency resolution and
discrimination of constant and dynamic tones in normal and hearing impaired
listeners" JASA 74, 1190-1199.

andy,
I have a paper coming out in january's jasa, which is largely a refutaion
of an earlier paper this tear (also in jasa) by cohen & chen. Both contain
some data on this topic
cheers

The following refs are about the masking patterns of FM tones:
S. Kemp, Acustica 1982, 50, 63-69;
A. Kohlrausch, in Basic Issues in Hearing (Duifhuis et al, eds),
    Academic P., 1988;
B.K. Smith et al., JASA 1986, 80, 1631-1637;
Smoorenburg & Coninx, Hearing Res. 1980, 3, 301-316.

I think that some work has been done on the masking patterns of
consonants, but I can't say where it was published immediately.

I hope this will help. Good luck.

Andrew;
    Not sure what you are looking for, but Terry Takahashi and I
recently published a paper that might be of interest:

    Takahashi TT and Keller CH (1992)  Simulated motion enhances
neuronal selectivity for a sound localization cue in background
noise.  J Neurosci 12:4381-4390.

    Basically, we tested neuronal tuning to interaural time
differences (ITDs) of tones buried in noise, figuring that the
sharpness of tuning reflected on the tones "detectability".  We
tested static tones presented at various ITDs and continuously moving
tones (binaural beats) that covered these same ITDs.  At all noise
levels, but most impressively at low signal to noise levels, the
moving tones were more "detectable".  Not so surprising considering
lateral inhibition, habituation and the like.
    Anyhow, I hope this helps.
