Frequency discrimination for pulsed versus modulated tones. 1978

H Fastl

Estimates of frequency discrimination for pulsed modulated tones were obtained by 11 observers at 350, 500, 1000, 4000, and 8000 Hz. At low frequencies, frequency DL's are larger for modulated than for pulsed tones; at 8000 Hz the contrary was found. Frequency DL's (difference limens) determined by different methods and procedures differed by a factor up to four; extreme individual frequency DL's, however, by a factor up to 27.
