Binaural 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 کاملMonaural and binaural contributions to interaural-level-difference sensitivity in human auditory cortex
Whole-brain functional magnetic resonance imaging was used to measure blood-oxygenation-level-dependent (BOLD) responses in human auditory cortex (AC) to sounds with intensity varying independently in the left and right ears. Echoplanar images were acquired at 3 Tesla with sparse image acquisition once per 12-second block of sound stimulation. Combinations of binaural intensity and stimulus pre...
متن کاملIllusory continuity of intermittent pure tone in binaural listening and its dependency on interaural time difference
Illusory continuity is known as a psychoacoustical phenomenon in hearing; i.e. an intermittent pure tone may be perceived as if it was continuous, when it is padded with enough large white noise. There are many researches related to this issue in monaural listening. It is said that such illusory continuity is observed when there is no evidence of discontinuity and level of the white noise is la...
متن کاملBinaural jitter with cochlear implants, improved interaural time-delay sensitivity, and normal hearing.
Laback and Majdak (1) recently showed that interaural timedelay (ITD) sensitivity in bilateral cochlear implant (BiCI) users can be improved at high rates by diotic randomization of the electrical pulse timing. They ascribed their result to ‘‘restarting’’ of the binaurally adapted auditory system. However, an alternative explanation is that randomizing electrical pulse rate introduced low-rate ...
متن کاملSensitivity for interaural time and intensity difference of auditory midbrain neurons in the grassfrog.
The sensitivity for interaural time (ITD) and intensity (IID) difference was investigated for single units in the auditory midbrain of the grassfrog. A temporally structured stimulus was used which was presented by means of a closed sound system. At best frequency (BF) the majority of units was selective for ITD as indicated by an asymmetrically (73%) or symmetrically (7%) shaped ITD-rate histo...
