Loudness and Loudness Discrimination Revisited
We present evidence that the psychophysical function relating loudness to sound pressure is governed by a nonlinear gain control system, one of whose functions is to protect the sensory system from overload. Specifically, the loudness function is altered nonlinearly when loud sounds are added in an identification task previously containing only soft sounds but not vice
متن کاملTemporal integration of loudness, loudness discrimination, and the form of the loudness function.
Temporal integration for loudness of 5-kHz tones was measured as a function of level between 2 and 60 dB SL. Absolute thresholds and levels required to produce equal loudness were measured for 2-, 10-, 50-, and 250-ms tones using adaptive, two-interval, two-alternative forced-choice procedures. The procedure for loudness balances was new and employed ten interleaved tracks to obtain concurrent ...
متن کاملLoudness growth in forward masking: relation to intensity discrimination.
The growth of loudness of a tone burst following an intense forward masker was measured as a function of the tone level. The level of the forward-masked tone was adjusted to balance the loudness of a standard tone presented without a forward masker, using a 2AFC, double-staircase, tracking procedure. The forward masker was a 90-dB SPL, 100-ms, 1000-Hz pure tone. The standard tone and the masked...
متن کاملLoudness scaling revisited.
The present work was undertaken in an attempt to evaluate whether it is reasonable to expect that categorical loudness scaling can provide useful information for nonlinear hearing aid fitting. Normative data from seven scaling procedures show that the individual procedures relate the perceptual categories differently to sound level and with a substantial between-subject variance. Hearing-impair...
متن کاملDisturbances of loudness perception.
This article reviews information on some auditory disorders that have in common a disturbance in loudness perception. The perceptual disturbances in these disorders have interchangeably been labeled "hyperacusis," "dysacusis," or "phonophobia." Our question concerns whether the loudness disturbances associated with these auditory disorders are sufficiently different as not to justify the equiva...
