Popis: The spatial awareness of patients with auditory dysfunction can be significantly limited by their ability to make use of binaural and monaural spatial cues. Although the reduction in sensation level associated with hearing loss can greatly diminish sensitivity to spatial cues, there is nonetheless great diversity in the spatial hearing abilities of listeners who are aging and/or experiencing hearing impairment. This chapter reviews the evidence of impaired and preserved binaural function in these listeners, collected over the past 100 years. This analysis reveals the need for further research with sufficient power to uncover the multiple factors associated with the spatial hearing difficulties experienced by older and hearing-impaired listeners. It also highlights the need for more work relating behavioral thresholds to physiology in studies using both human patients and animal models. Finally, the chapter highlights the untapped potential that assessments of binaural ability hold for better characterizing auditory dysfunction and for improving the rehabilitation provided by hearing aids and cochlear implants.
