The research examines mechanisms limiting speech and auditory perception in challenging acoustic conditions among adults with sensorineural hearing loss, cochlear implant...
- The National Institute on Deafness and Other Communication Disorders, part of the Department of Health and Human Services National Institutes of Health, awarded the University of Massachusetts $203,125 under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) on July 20, 2026. The award funds research examining how the brain processes spatial hearing—the ability to locate and isolate sounds in noisy environments—from the brainstem through the cortex and across...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Wisconsin - Madison $188,421 on May 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to develop behavioral and neurophysiological assessment tools for evaluating speech fine structure processing in noise. The recipient will create psychoacoustic and non-invasive electrophysiological (multichannel EEG) instruments to assess the perception and neural...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Wisconsin–Madison $201,890 on August 14, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to build epidemiological evidence addressing research gaps in hearing screening of older adults. The project will characterize the natural history of age-related hearing loss and identify optimal screening approaches by leveraging data from five longitudinal...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Wisconsin - Madison $1,166,250 on September 16, 2025, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate cortical population coding and network effects of cochlear implant stimulation during behavioral tasks. The research addresses gaps in understanding why cochlear implant outcomes vary significantly among users, despite over one million people...
- The National Institute on Deafness and Other Communication Disorders awarded the University of Pittsburgh $664,448 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds investigation of how heterogeneous neural responses in auditory cortex and secondary motor cortex contribute to auditory learning and perception. The project combines large-scale neural recordings with optogenetic manipulations to examine how local auditory...
The National Institute on Deafness and Other Communication Disorders awarded the University of Texas at Austin $192,953 on September 1, 2026, under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) to investigate the role of extended high frequencies on speech perception challenges in aging. The research addresses a critical gap in clinical audiology: many adults experience difficulty understanding speech in noisy environments by midlife despite normal results on standard hearing tests. Current audiometric assessments do not routinely measure sensitivity to extended high frequencies (frequencies above 8 kilohertz), even though extended high-frequency thresholds decline first with age and correlate with speech perception difficulties. The project applies computational modeling and neuroimaging to demonstrate that extended high-frequency cues enhance phoneme decoding accuracy under noisy conditions and that middle-aged adults show reduced neural differentiation of speech sounds even when traditional audiometric frequencies appear normal. Work is performed in Austin, Texas, with a period of performance extending from September 1, 2026, through June 30, 2029. The assistance type is a project grant, classified within the NIH Research Related to Deafness and Communication Disorders program, which supports investigation of hearing, balance, and communication disorders across eligible research institutions.
