M. Patrick Feeney, Ph.D.

Telephone: 503-273-5306

Congratulations to Dr. Feeney! He has been recognized by the American Academy of Audiology for his work to improve the lives of Veterans and others affected by hearing loss. The academy presented Feeney with the 2019 Jerger Career Award for Research in Audiology. Over the last 30 years, his research has focused on peripheral and central auditory function in Veterans and others. For more about the award, click here.

Research interests and current projects 

Dr. Feeney’s research program involves the evaluation of peripheral auditory function, with a focus in the area of middle-ear and cochlear assessment and diagnosis. He recently completed an NIH funded multi-center, multiple-PI R01grant from NIDCD with collaborators Douglas Keefe, Ph.D. of the Boys Town National Research Hospital and Lisa Hunter, Ph.D. at the Cincinnati Children’s Hospital on the application of a wideband middle-ear and cochlear test battery. They evaluated the use of wideband acoustic transfer functions to evaluate middle ear disorders in adults and infants, and to use wideband, click-evoked otoacoustic emissions in the assessment of ototoxicity in patients with cystic fibrosis (CF). Additional work in planned to further evaluate auditory function in CF patients to include functional effects of ototoxicity on speech processing. He is collaborating with Keefe and Kim Schairer, Ph.D. of VA at Mountain Home TN in a multi-site study to examine the use of a wideband test battery including reflectance and otoacoustic emissions to evaluate Veterans with sensorineural and conductive hearing loss. An additional research focus is a current project evaluating the use of automated adult hearing screening, for which he serves as PI on an NIH-NIDCD R21/R33 grant Community-based kiosks for hearing screening and education.
