Auditory phase opponency: A temporal model for masked detection at low frequencies

We present a model for tone-in-noise detection at low frequencies that includes a physiologically realistic mechanism for processing the information in neural discharge times. The proposed model exploits the frequency-dependent phase properties of the tuned filters in the auditory periphery and uses cross-auditory-nerve-fiber coincidence detection to extract temporal cues. Information in the responses of model coincidence detectors is …
