Re: AUDITORY Digest - 10 May 2001 (#2001-88)



All,

It is certainly tempting to say that if Al B. is uncertain about "streams"
vs. "groups" the rest of us should avoid the issue.  But that question did
cause me to reflect over the reason for the quick acceptance, some years ago
now, of the concept of "streams", which might have been argued to have been
unnecessary, given the rich vocabulary already established by Gestalt
psychologists.  Perhaps it was already obvious to most of you...but it just
occurred to me that we did need a word to characterize grouping phenomena in
audition, where the temporal dimension dominates.  The Gestalt vocabulary
had been developed primarily with static visual displays in mind, even
though its founders clearly believed that the grouping principles were valid
for all modalities.  "Streams and streaming" nicely capture the temporal
dimension that is the essential property of most auditory grouping
phenomena.

One corollary observation (I owe it to my esteemed colleagues Eric Prame
and Bob Efron):

Slow (~1 to ~5 Hz) sinusoidal amplitude modulation produces one perceptual
event per cycle (coinciding with the peak or the onsetof the positive
ramp). Slow sinusoidal frequency modulation produces two.

At all points for which there was regular glottal vibration.  By raw I mean
that no "speech target" selection process was involved.

I also tried doing statistics of maxima or minima of contiguous voiced
portions (which roughly correspond to "breath groups") as a rough but
plausible target selection process.  No sign of a note-related structure in
the distribution of values.

Subject: A note on notes

The following comment may strike some as pedantic, but I believe it
is good practice to keep scientific terminology in order. I would
like to suggest that, in scientific articles or exchanges on
music-related subjects, the word "note" not be used when referring to
sounds. Although this usage is common in everyday language (and
sometimes hard to avoid, I admit), the term "note" should refer only
to a printed symbol on paper. The audible consequence of playing a
note on an instrument is a tone. Notes have neither pitch nor
duration, only tones do. The term "note" in music is analogous to the
term "letter" in language, which also denotes a written symbol, not a
sound.

If anyone disagrees with this proposal, I'd be interested in the
counterarguments.

Actually, sounds with _fast_ onsets and _slow_ decays are judged as _less

This is an Americanism -- possibly from deriving from the influence of the
German "ton" -- hence the use of "12-tone music" in the US and "12-note
music" in the UK. I agree that it would be helpful to distinguish the sound
from the printed symbol, but in British English the term "tone" refers to an
interval (equal to two semitones, American "whole-tone"), so this seems an
undesirable way to draw this distinction for speakers of British English.

Subject: inhibition in cortical vs. subcortical neurons

Dear List,
I was wondering if any experts out there could point me to references that
discuss the relative strength of inhibition (or suppression) in cortical
versus subcortical neurons.  I'm interested in how inhibitory sidebands may
play a stronger role in creating a "band reject" region for cortical
neurons as compared to lower order auditory neurons.

The only comment I've found thus far was in Brosch and Schreiner (1997)
Time course of forward masking tuning curves in cat primary auditory
cortex. J Neurophys 77, p. 939.

Thanks,

Answer:

Not so. The first meaning of "tone" listed in the Oxford English
Dictionary is "A musical or vocal sound, esp. with reference to its
pitch, quality, and strength". The interval meaning is listed only
under "4b". This additional meaning is no impediment whatsoever to
using "tone" with its primary meaning.

Andy Vermiglio wrote:

"The audible consequence of playing a note on an instrument is a tone."

Does this hold true for untuned percussion instruments?

Answer:

Perhaps I should have said "sound" for greater generality. My main
point was that "note" should not be used to refer to musical sounds.

I just checked the oxford english dictionary, and one of the definitions
of tone is:

"A musical or vocal sound considered with reference to its quality, as
acute or grave, sweet or harsh, loud or soft, clear or dull."

which appears to refer not to an interval but to single sound. So it
looks as though it can refer to both intervals and single sounds in
British English.

Also, don't Americans also use the word 'tone' to refer to both an
interval and a single sound? (I have seen the words "semi-tone" and
"tone" etc. used to refer to intervals in American journals.)

So is it really an Americanism?

Certainly -- I didn't mean to suggest that "tone" never means a single sound
in British English, or that it never means an interval in US English.
But while we have our dictionaries out, the OED also gives, under "note",
the meaning "a single tone of definite pitch made by a musical instrument,
the human voice, etc."

> Perhaps I should have said "sound" for greater generality. My main

And my point was simply that "tone" merely replaces one ambiguity with
another.

Hi Tony and List,

I know what a stream is -- a time-varying sound or sequence of
sounds, treated by the auditory system as coming from a single
sound source.  However, I don't know what is meant by a group.
Perhaps the context  in which this term was found would be
informative.  How was it used in the original source?
