Temporal Processing and Speech Perception in Noise by Listeners with Auditory Neuropathy
Figure 6
Frequency modulation detection threshold (FMDL) for 2 Hz and 10 Hz modulation frequencies as function of carrier frequencies (0.5, 1, 2, and 4 kHz) expressed as ΔF divided by equivalent rectangular bandwidth (ERB).
ΔF/ERB values were grossly abnormal at lower frequencies and lean towards normal function at higher frequencies.
