✦ Synopsis

A workable model of human auditory}brain system including the auto-correlation function (ACF) and the interaural cross-correlation function (IACF) has been reported [1]. Subjective evaluations can be described by physical factors extracted from both the ACF of sound source and the IACF. The purpose of this study is to "nd a recommended integration time (2¹) P by using several noise and sound sources existing in an o$ce. Results show the most suitable integration interval from the viewpoints of the loudness and the pitch can be determined in relation to the e!ective duration ( C ) of the sound source.

This is the report of an investigation into the sensation of the duration of environmental noise simulated by mixing a pure tone (1 kHz) with white noise. In paired-comparison tests "ve subjects judged whether simulated-environmental-noise stimuli were longer or shorter than a standard pure-tone sti
