In order to get a systematic picture of how various hearing impairments and neurologic disorders may affect sound localization, psychophysical spatial- and lateralization-discrimination measurements were performed on 140 subjects, including 69 with different types of hearing impairments, 32 with neurological diseases, and 39 with normal hearing. The(More)
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 frequencydependent phase properties of the tuned filters in the auditory periphery and uses cross-auditory-nerve-fiber coincidence detection to extract(More)
Masked thresholds can improve substantially when a signal is spatially separated from a noise masker (Saberi et al. 1991). This phenomenon, termed “spatial release from masking” (SRM), may contribute to the cocktail party effect, in which a listener can hear a talker in a noisy environment. The purpose of this study is to explore the underlying neural(More)
34 The lateral superior olive (LSO) is the first nucleus in the ascending auditory pathway 35 that encodes acoustic level information from both ears, the interaural level difference 36 (ILD). This sensitivity is believed to result from the relative strengths of ipsilateral 37 excitation and contralateral inhibition. The study reported here simulated(More)

Over the last few years, music fans have filmed portions of live concerts on their mobile phones or compact video cameras and upload this footage to YouTube. This article focuses on what motivates “filmers” to place a camera between themselves and the performance on stage to capture footage consumed later. A notable facet of the culture of concert filming(More)
