“Long-Time” Differential Intensity Sensitivity
Irwin W. Pollack · The Journal of the Acoustical Society of America · 1955
This note considers the differential intensity threshold made over “long” (12, 1, 3 day. and longer periods) time intervals. Its purpose is to point out experimentally what is obvious from personal experience. When a given sound is repeatedly experienced with no variation, small changes in that sound can be detected even over long time intervals.
