摘要:
An experiment is described in which perstimulatory loudness adaptation was measured under heterophonic conditions using simultaneous dichotic loudness balance procedures on normal listeners. The adapting signals were 500 and 3000 Hz presented at 70 dB SPL for 12 min, the last 5 min of which involved perstimulatory loudness balances. A tracking technique and the method of constant stimuli were employed. The results indicated that continuous stimulation did not significantly decrease the loudness of the adapting signal. Thus, under test conditions that reduce or eliminate binaural interaction, suprathreshold loudness adaptation is essentially absent for pure‐tone signals of 500 and 3000 Hz at 70 dB SPL.
