Abstract
The control continuous tone (1000 Hz) was presented in one ear starting at an intensity of 100 dB SPL with an attenuation rate of 1 dB per second by descending manner. The balancing comparison continuous tone (1000 Hz) was presented in the opposite ear also starting at 100 dB SPL with an attenuation rate of 5 dB per second. Three trained subjects with normal hearing were instructed to release the Bekesy switch to increase the loudness and to push the switch to reduce the loudness of the comparison tone. While there were inter‐subject variations, our data indicated that there was continuous decrease in the ratio of balanced loudness levels between tones with attenuation rates of 5 dB per second and 1 dB per second as the functions of time and decreasing intensity. This is considered a manifestation of normal adaptation. Present results were compared with our previous reports for the threshold differences produced by different attenuation rates at the suprathreshold starting intensities.
