About this program
The National Institute on Deafness and Other Communication Disorders (NIDCD) of the Department of Health and Human Services National Institutes of Health awards grants under Assistance Listing 93.173 to support research investigating solutions to problems directly relevant to individuals with deafness or disorders of human communication in the areas of hearing, balance, smell, taste, voice, speech, and language, with the most recent award dated February 28, 2027.
The program funds basic and translational research into the biology and pathophysiology of communication disorders and sensory systems. Recent awards span neural mechanisms of speech motor control in stuttering, sustained siRNA-LNP delivery for vocal fold scarring, vestibular population encoding for balance restoration, development of high-resolution endoscopes for olfactory imaging, brain-computer interfaces for speech restoration in paralysis, cochlear hair cell vulnerability following cisplatin exposure, genetic biomarkers predicting cochlear implant outcomes, and language development trajectories in deaf and hard of hearing children. The program also funds applied work on hearing aid signal processing, speech intelligibility in dysarthria, caregiver-mediated language interventions for autistic children, and novel diagnostics for auditory and olfactory dysfunction.
Over 12,600 awards totaling $11.34 billion in federal dollars obligated have been disbursed since 1974. Activity has remained steady, with 202–280 awards per year over the past five years and six awards recorded in 2027 to date. The portfolio is dominated by Project Grants (96% of awards), with smaller shares of Block Grants (4%) and Cooperative Agreements (1%). The National Institute on Deafness and Other Communication Disorders accounts for 3,483 awards ($8.05 billion federal), the broader NIDCD portfolio across NIH institutes adds 8,863 awards ($2.96 billion federal), and HHS and other NIDCD divisions contribute the remainder. Representative award values for predoctoral and postdoctoral fellowships range from $40,716 to $244,740, while R01 research grants range from $369,413 to $957,448.
No grant opportunities are currently open with posted due dates; recent forecasted opportunities include the NIDCD Research Fellowship for Audiologists (audiologists in PhD programs), Small Business Transition Grants for entrepreneurial scientists, the Advancing Screening, Diagnosis, and Referral for Late Talking Children initiative (birth-to-three screening and referral), and transformative imaging technologies for the olfactory system. The program continues to accept applications under standing parent NOFOs for R01, R21, R56, SBIR, STTR, and training grants (T32, T35, F30–F32) relevant to deafness and communication disorders research.
Objective and description

- Description
Research grants make up the largest category of funding and support by NIDCD. These grants may be awarded to universities, medical and other health professional schools, colleges, hospitals, research institutes, for-profit organizations, and government institutions that sponsor and conduct biomedical research and development. Research grants may provide funds for salaries, equipment, supplies, travel, and other allowable direct costs of the research as well as for indirect costs to the sponsoring institution or organization.
Eligibility
- Applicant eligibility
Project Grants and Centers Grants: Any public, private, nonprofit, or for-profit institution is eligible to apply. For-profit institutions are not eligible for institutional National Research Service Awards. All proposals are reviewed for scientific merit, for evaluation of the qualifications of the investigators, for adequacy of the research and/or research training environment and for significance of the problem. Approved proposals compete for available funds. Awardees of almost all Research Career Development Programs must be citizens or have been admitted to the United States for permanent residence. Candidates must be nominated for the program by a nonfederal public or private nonprofit institution located in the United States, its possessions or Territories. To be eligible, postdoctoral NRSA trainees and fellows must have a professional or scientific doctoral degree (PhD, MD, DO, DC, DDS, DVM, OD, DPM, ScD, EngD, Dr PHPhD, MD, DO, DC, DDS, DVM, OD, DPM, ScD, EngD, Dr PH, DNSc, ND {Doctor of Naturopathy}, PharmD, DSW, PsyD, AUD or equivalent doctoral degree from an accredited domestic or foreign institution). SBIR grants can be awarded only to domestic small businesses (entities that are independently owned and operated for profit, and have no more than 500 employees). Primary employment (more than one-half time) of the principal investigator must be with the small business at the time of award and during the conduct of the proposed project. In both Phase I and Phase II, the research must be performed in the United States or its possessions. To be eligible for funding, an SBIR grant application must be approved for scientific merit and program relevance by a scientific review group and a national advisory council. STTR grants can be awarded only to domestic small business concerns which "partner" with a research institution in cooperative research and development. At least 40 percent of the project is to be performed by the small business concern and at least 30 percent by the research institution. In both Phase I and Phase II, the research must be performed in the U.S. and its possessions. To be eligible for funding, a grant application must be approved for scientific merit and program relevance by a scientific review group and a national advisory council.

- Uses of assistance
Project Grants and Centers Grants may be used to provide salaries, equipment, supplies, travel, and other expenses for research. The grantee institution is obliged to expend grant funds prudently for the purposes as stated in the application and award document. Some National Research Service Awards (NRSAs) are issued on behalf of an individual for research training in specified biomedical and behavioral research areas. Other training grants are made to institutions to enable them to make NRSAs to individuals selected by them. Each postdoctoral individual who receives an NRSA may be obligated, upon termination of the award, to comply with certain service and payback provisions. Mentored and unmentored career development awards are made to enhance the independent research capability of highly promising individuals during the formative stages of their careers. Small Business Innovation Research (SBIR) Program: Phase I grants, typically 6 months in duration, are to establish the technical merit and feasibility of a proposed research effort that may lead to a commercial product or process. SBIR Phase II grants are for the continuation of the research efforts initiated in Phase I and that are likely to result in commercial products or processes. STTR Phase I grants, normally of 1-year duration, are to determine the scientific, technical, and feasibility of the proposed cooperative effort. Phase II funding is based on scientific and technical merit and commercial potential of the application. Grant funds may be expended only for the purpose stated in the application and award document.
