NIDCD-Funded Research Projects on Accessible and Affordable Hearing Health Care

Working with scientists and clinical researchers throughout the United States, the NIDCD supports clinical and translational research to develop and test novel strategies to overcome barriers to care and to improve the quality of life for the millions of adults with hearing loss.

As of January 2021, the NIDCD supports 19 active research projects (below) on accessible and affordable hearing health care (AAHHC). We also list (below, second chart) completed projects on accessible and affordable hearing health care. The projects are listed alphabetically by the last name of the principal investigator (PI). In some cases, a project might begin under one type of grant mechanism and continue under another mechanism, with the same project name. Completed projects that are continuing under a different funding mechanism are marked with an asterisk(*).
