Abstract

The loudness of a 1,600-Hz pure-tone signal partially masked by a 1,000-Hz, 70-dB SPL masker is experimentally examined using the loudness matching method. As for two of the four subjects who participated in the experiment, the loudness of the signal for signal levels higher than 45 dB SPL was found to be enhanced in spite of the masking. This phenomenon disappeared in the presence of one-third-octave band noise whose center frequency was 2,500 Hz. These results suggest that judgments of the loudness are affected by aural combination tones when the masker used is a pure tone. Five loudness functions proposed earlier were tested to determine if they can explain the loudness of a pure tone partially masked by another pure tone. As a result, the formula using the driven firing rate function of the auditory sensory receptor shows good agreement with some of the data.
