CONTINUITY IN ALTERNATELY SOUNDED TONE AND NOISE SIGNALS IN A FREE FIELD

Two experiments are reported that employed 10 normally hearing listeners who demonstrated an ability to concentrate on an interrupted white noise that alternated with a tonal burst. The purpose of the study was to demonstrate continuity effects in a free field situation and to investigate the effects of frequency and level of the signal component, the duration of the noise component, and the angular separation of the two components. The results showed that the level and the duration variables effected changes in continuity thresholds. Angular separation did not appreciably affect the perception of continuity in the noise. © 1969, Acoustical Society of America. All rights reserved.
