Frequency selectivity in normal-hearing listeners using a sweep, frequency-modulated masker: a preliminary report.

It was the objective of this preliminary investigation to determine whether psychoacoustic tuning curves could be obtained on naive listeners utilizing a sweep, frequency-modulated masker. Psychoacoustic tuning curves were obtained on 10 normal-hearing young adult listeners. A simultaneous masking paradigm was utilized. The probe tone was a 2 kHz signal and the masker was a sweep, frequency-modulated tone between and including 750 Hz and 4 kHz. A mean Q value of 4.93 with a standard deviation of 0.85 was obtained from the subjects. Clinical implications and needs for further research are discussed.
