Re: [AUDITORY] Continuous noise during a loudness test.

[Sabine Meunier <meunier@xxxxxxxxxxxxxxx>]

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.
