Stereausis: A Binaural Processing Model
Ng, Samuel Jiawei
MetadataПоказать полную информацию
The stereausis network model measures interaural differences by detecting spatial disparities between instantaneous outputs from both ears. It can detect the location of a sound source at all frequencies as well as detect and enhance noisy signals by comparing the spatiotemporal responses of an auditory nerve fiber array at various horizontal shifts. Cross correlation of cochlear responses is found by combining an ipsilateral input at a characteristic frequency with contralateral inputs at other frequencies.
