Efficiently Characterizing the Deficits Comprising Central Hearing Loss
This project, R01DC015051 funded by the National Institute of Deafness and Communication Disorders, addresses our brain’s ability to hear. Most diagnoses of hearing loss focus on the audiogram, which is not sensitive to dysfunction at many of the additional processing stages associated with auditory perception. For example, recent data from many laboratories, including our own, have shown clear auditory processing deficits both in older listeners and in patients who have suffered traumatic brain injury, despite normal audiograms. Through this proposal, we developed the app PART that forms the basis of a new clinical test battery for central auditory dysfunction that can support accurate diagnosis of a much wider range of the difficulties that can lead to auditory complaints.
