[AUDITORY] Loudness matching
Dear Gauthier,
One paper you might read looks at tonal and noise masking, and brings
them into agreement, by a transformation into the loudness domain.
This solves the problem of the near miss to Weber's Law, which was a
large problem with classical loudness data.
Personally I suggest you avoid loudness estimation methods due to the
very large variance associated with that method. Besides its basically
in agreement with matching experiments, as was demonstrated by Fletcher
Munson 1933.
Allen, Jont B. and Neely, S. T. (1997) "Modeling the relation between
the intensity JND and loudness for pure tones and wide--band noise"; /J.
Acoust. Soc. Am.,/ *102* (6) pp 3628--3646, December pdf

There is also this sort of cue idea:
Grimault, N and McAdams, S. and Allen, Jont B. "Auditory scene analysis:
a prerequisite for loudness perception," Book Title: "International
Symposium Hearing Oldenburg Germany" Publisher *Springer* Eds:
Kollmeier, Birger and Klump, Georg. pdf
<http://jontalle.web.engr.illinois.edu/Public/GrimaultMcAdamsAlle07.pdf>
The pdf links should work. If not the papers are available at my website
auditorymodels.org (publications)

Dear Gauthier,
You can look to the work on loudness adaptation by Scharf, Canévet,
Botte, ... (I join a review paper). They measured loudness of long
signals. They used magnitude estimation and usually with pure tones. It
is far from what I have understood you are looking for, but that can help.
Otherwise a lot of experiments on masking use background noise to mask
combination tones. But it is masking, not loudness...
best regards
Sabine

Dear list,
I am currently working on directional loudness as part of my first
year of PhD in the University of Brest, France.
I am planning an experiment of loudness for low-frequency pure tones
in the quiet (i.e. with internal noise only) and in presence of an
external low-level noise. In order to get the subject used to external
noise just like they are with internal noise, I was thinking of doing
the whole external noise part of the test with a continuous backing
noise, during from the very beginning to the very end of this part.
In the literature, all I could find in loudness matching procedure
used gated noises, appearing and disappearing a few seconds
before/after the target stimuli.
Does any of you have ever heard of a loudness matching procedure (or
similar) using a continuous noise all over the duration of the test ?
Best regards,
Gauthier Berthomieu.
