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 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 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...
متن کاملInteraural time sensitivity dominated by cochlea-induced envelope patterns.
To localize sounds in space, humans heavily depend on minute interaural time differences (ITDs) generated by path-length differences to the two ears. Physiological studies of ITD sensitivity have mostly used deterministic, periodic sounds, in which either the waveform fine structure or a sinusoidal envelope is delayed interaurally. For natural broadband stimuli, however, auditory frequency sele...
متن کاملSensitivity of inferior colliculus neurons to interaural time differences in the envelope versus the fine structure with bilateral cochlear implants.
Bilateral cochlear implantation seeks to improve hearing by taking advantage of the binaural processing of the central auditory system. Cochlear implants typically encode sound in each spectral channel by amplitude modulating (AM) a fixed-rate pulse train, thus interaural time differences (ITD) are only delivered in the envelope. We investigated the ITD sensitivity of inferior colliculus (IC) n...
