This Project Grant award for $583,125 from the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders program (CFDA 93.173) will fund a study to develop and assess a novel Speech Accessibility Index (SAI) that quantitatively evaluates children's access to language in real-world environments. The research will also examine the feasibility of using EEG to assess preschoolers' neurophysiological correlates of...
The National Institute on Deafness and Other Communication Disorders (NIDCD) awarded a $610,725 Project Grant (CFDA 93.173 - Research Related to Deafness and Communication Disorders) to the University of Pittsburgh to conduct research on physiological mechanisms contributing to challenges faced by individuals with sensorineural hearing loss in understanding speech, especially in noisy environments. The research program aims to characterize the effects of distorted cochlear tonotopicity and...
This $200,625 Project Grant was awarded by the National Institute on Deafness and Other Communication Disorders (NIDCD), under the Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award will fund a research study titled "Uncovering the Neural Mechanisms and Antecedent Factors of Listening Difficulty in Preterm Children." The study aims to investigate the neural mechanisms and clinical antecedents underlying listening difficulty in school-age...
This Project Grant award, titled "The Impact of Noise on Temporal Integration of Speech in the Human Brain", is funded by the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders program (CFDA 93.173).

This $369,108 Project Grant was awarded by the National Institute on Deafness and Other Communication Disorders (NIDCD), under the federal Research Related to Deafness and Communication Disorders program (CFDA 93.173). The award funds the development of a new computational model of the human auditory subcortex to investigate how binaural coding and efferent gain control affect the perception of complex sounds, including in normal-hearing and hearing-impaired listeners. The model simulates...
This federal Project Grant award, funded by the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders program (CFDA 93.173), provides $137,305 to support research on the mechanisms underlying adaptive auditory processing. The goal is to determine how descending projections from the auditory cortex to subcortical regions, such as the inferior colliculus and medial geniculate body, enable contextual processing...

This federal Project Grant award from the National Institute on Deafness and Other Communication Disorders (NIDCD), under the Research Related to Deafness and Communication Disorders program (CFDA 93.173), provides $144,795 to The House Institute Foundation to conduct research examining the effects of background noise on real-time speech processing in children with normal hearing and children using hearing aids.

The research aims to investigate how speech-shaped noise and two-talker speech maskers impact the speed of lexical access (word recognition) and semantic activation (word meaning) during speech recognition in school-age children. The study will compare these processes between children with normal hearing and children using hearing aids, and explore factors such as cognitive skills and auditory access as predictors of individual differences. The knowledge gained will inform guidelines for classroom acoustics to promote effective listening and learning environments, as well as the development of interventions to improve listening and language comprehension for children using hearing aids. The award period is from May 1, 2025 to April 30, 2028.
