Sensitivity to Envelope Interaural Time Differences at High Modulation Rates
Sensitivity to interaural time differences (ITDs) conveyed in the temporal fine structure of low-frequency tones and the modulated envelopes of high-frequency sounds are considered comparable, particularly for envelopes shaped to transmit similar fidelity of temporal information normally present for low-frequency sounds. Nevertheless, discrimination performance for envelope modulation rates abo...
متن کاملModeling interaural-delay sensitivity to frequency modulation at high frequencies.
Interaural-delay sensitivity to high-frequency (> or = 3 kHz) sinusoidal-frequency-modulated (SFM) tones is examined for rates from 25 to 800 Hz and depths of -12 to 18 dB. Comparison is made to thresholds obtained for sinusoidal-amplitude-modulated (SAM) tones for the same observers and modulation rates. Both SAM and SFM threshold-by-rate functions are U-shaped with optimum sensitivity to SFM ...
متن کاملNeural Sensitivity to Interaural Envelope Delays
Interaural time differences (ITDs) are important cues for mammalian sound localization. At high-frequencies, sensitivity to ITDs, which are conveyed only by the envelope of the waveforms, has been shown to be poorer than sensitivity to ITDs at low-frequencies, which are conveyed primarily by the fine-structure of the waveforms. Recently, human psychophysical experiments have demonstrated that s...
متن کاملBinaural jitter improves interaural time-difference sensitivity of cochlear implantees at high pulse rates.
Interaural time difference (ITD) arises whenever a sound outside of the median plane arrives at the two ears. There is evidence that ITD in the rapidly varying fine structure of a sound is most important for sound localization and for understanding speech in noise. Cochlear implants (CIs), neural prosthetic devices that restore hearing in the profoundly deaf, are increasingly implanted to both ...
متن کاملNeural sensitivity to interaural time differences: beyond the Jeffress model.
Interaural time differences (ITDs) are a major cue for localizing the azimuthal position of sounds. The dominant models for processing ITDs are based on the Jeffress model and predict neurons that fire maximally at a common ITD across their responsive frequency range. Such neurons are indeed found in the binaural pathways and are referred to as "peak-type." However, other neurons discharge mini...
