The effect of psychophysical method on the loudness of continuous and interrupted pure tones
Abstract
Using the Bekesy tracking method for such suprathreshold loudness judgement tasks as most comfortable loudness and recalled loudness measurements, normal listeners have tracked C tones at lesser intensities than I tones. The resulting continuous/interrupted (C/I) separations have ranged up to 22 db. Although several variables which contribute to this effect have been identified, explanations of the C/I separation have not been in agreement. A variety of psychophysical methods are used to determine loudness of C and I tones. Results demonstrate that the C/I separations obtained during suprathreshold Bekesy tracking tasks are largely caused by the measurements method rather than by differences in C and I tone loudness.
