The federal Project Grant award R01DC020962 for $656,723.00, granted by the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders program (CFDA 93.173), supports research to validate a new protocol for recording Distortion Product Otoacoustic Emissions (DPOAEs) and expand their clinical applications. The key objectives are to:

  1. Validate a new DPOAE recording protocol using frequency-specific stimulus conditions matched to local cochlear properties to better detect mild-to-moderate hearing loss.
  2. Utilize DPOAE growth functions to differentiate effects of aging from noise-induced cochlear changes.
  3. Develop a two-dimensional DPOAE metric to estimate cochlear tuning and identify hearing-related declines beyond changes in sensitivity.

The award will also extend the frequency bandwidth of DPOAE applications to the highest frequencies of human hearing. A sub-award of $69,330 was made to the University of Iowa to support this research. Overall, the project aims to transition DPOAEs from a screening tool to a more potent clinical diagnostic and monitoring technology.
