Congressionally Directed Medical Research Programs – U.S. Department of Defense 

The Hearing Restoration Research Program (HRRP) under the Congressionally Directed Medical Research Programs (CDMRP), U.S. Department of Defense, supports innovative biomedical research aimed at restoring auditory function and preventing hearing loss among service members, veterans, and military families. Hearing loss is one of the most common service-connected disabilities in the U.S. military. Chronic exposure to weapons fire, explosive blast overpressure, aircraft engines, heavy vehicles, and industrial machinery creates a high incidence of auditory injury, tinnitus, and permanent hearing impairment. HRRP addresses this critical readiness challenge by funding research that advances hearing protection, regeneration, precision diagnostics, and long-term rehabilitation. 

HRRP emphasizes scientific exploration across auditory neuroscience, sensory hair cell regeneration, cochlear synaptopathy, neuroplasticity, electrical stimulation, stem-cell repair, inner-ear pharmacology, and advanced auditory prosthetics. Proposals may explore mechanistic pathways, novel regenerative strategies, biological or gene-therapy platforms, neurotrophic modulation, advanced signal processing for hearing-assistive devices, machine-learning-driven sound interpretation, or rehabilitative technologies that enhance service member communication in battlefield and training environments. 

Eligibility spans academic medical centers, universities, nonprofit institutes, Veterans Affairs facilities, federally funded R&D laboratories, biotechnology companies, and qualified for-profit entities working on dual-use auditory technologies. Applications may involve preclinical mechanistic science, animal models, validation of emerging therapeutics, translational strategies for cochlear protection, neuro-restorative interventions, implantable technologies, or advanced diagnostic and monitoring platforms. Rehabilitation and human-performance research—especially involving communication under noise burden, immersion simulators, or digital cognitive-auditory training—are highly relevant. 

The HRRP review process evaluates scientific merit, innovation potential, technical feasibility, military health relevance, implementation pathway, and benefit to readiness or long-term quality of life. Programmatic review then considers portfolio balance, duplication risk, and alignment with CDMRP-directed priorities. Strong submissions clearly justify how restoring auditory function or reducing hearing injury could improve unit performance, retention, safety, communication effectiveness, and lifelong outcomes for military beneficiaries.
