Range and regression, loudness scales, and loudness processing: toward a context-bound psychophysics.
How does context affect basic processes of sensory integration and the implicit psychophysical scales that underlie those processes? Five experiments examined how stimulus range and response regression determine characteristics of (a) psychophysical scales for loudness and (b) 3 kinds of intensity summation: binaural loudness summation, summation of loudness between tones widely spaced in frequ...
متن کاملReal-time Visualisation of Loudness along Different Time Scales
We propose a set of design criteria for visualising loudness features of an audio signal, measured along different time scales. A novel real-time loudness meter, based on these criteria, is presented. The meter simultaneously shows short-term loudness, long-term loudness and peak level. The short-term loudness is displayed using a circular bar graph. The meter displays the longterm loudness by ...
متن کاملNo Unified Scales for Perceptual Magnitudes: Evidence from Loudness
In this article we consider whether perceptual magnitudes are represents on unified underlying scales. We exploit the ubiquitous sequential effects seen in judgments concerning the attributes of simple perceptual stimuli. Participants made judgments about the intensity of sinusoidal tones and white noise hisses. On each trial in Experiment 1, participants heard a tone and a hiss and judged whic...
متن کاملLoudness 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 ...
