Re: [AUDITORY] JND values for tactile and audio amplitude signal decrease

[Massimo Grassi <massimo.grassi@xxxxxxxx>]

Dear Alfonso,

not sure this is what you need but I remember this (abrupt chance):
https://asa.scitation.org/doi/abs/10.1121/1.420086
Oxenham, A. J. (1997). Increment and decrement detection in sinusoids as
a measure of temporal resolution. The Journal of the Acoustical Society
of America, 102(3), 1779-1790.

and this (continuous change):
https://asa.scitation.org/doi/abs/10.1121/1.381431
Small Jr, A. M. (1977). Loudness perception of signals of monotonically
changing sound pressure. The Journal of the Acoustical Society of
America, 61(5), 1293-1297.
