Dear List Can anyone tell me if there is any experimental data to suggest that there may be something peculiar in the discrimination of loud low frequency tones, between about 50 Hz and 800 Hz, and above about 90 dB SPL? For example, is it the case that either intensity and/or frequency discrimination gets better above about 90/100 dB SPL for low frequencies, but not for tones of say 2 kHz or above? In other words, is there any evidence of a mechanism that cuts in for loud low frequencies (other than normal phase-locking)? Any comments/references gratefully received. Cheers Neil Todd
