Abstract
In spite of its interest for acoustics, the intensive difference limen for sound has not been determined over a comprehensive range of frequency and amplitude. In the present experiment we have determined the difference limens for discrete intensive discrimination at five frequencies ranging from 128 cycles to 1000 cycles with intensities from 0.02 bars r.m.s. pressure to 3.4 bars (−65 db to −15 db). Both the physical conditions and the psychological judgment have been carefully controlled. The data yield a value for Δ db of 2.4 db in the middle range of intensities (−35 db to −15 db or 35 SL to 70 SL.)This publication has 1 reference indexed in Scilit:
