Discrimination of nonlinear frequency glides.

摘要: Discrimination thresholds for short duration nonlinear tone glides that differed in glide rate were measured order to determine whether cues related of frequency change alone sufficient discrimination. Thresholds rising and falling 50-ms 400-ms duration, spanning three excursions (0.5, 1, 2 ERBs) at center frequencies 2.0, 6.0kHz) measured. Results showed discrimination was possible when initial final identical. a different those found previous studies using linear where endpoint or information is available as added cues. The pattern results suggestive mechanism sensitive spectral changes time. increased the transition span increased, particularly above spans 1 ERB. Weber fraction associated with these 0.6–0.7. Overall, consistent an ...
