Hearing Problems Related to Noise Exposure

Hearing Problems Related to Noise Exposure

We aim to understand hearing problems that are not detected in standard clinical practice.

The purpose is to identify early signs of noise exposure damage which are not currently identified on a standard hearing test. This involves studying groups of normal hearing people who do, and do not, have a history of noise exposure, tinnitus, or trouble hearing speech in noise. This group, for example, may include professional musicians, auto mechanic specialists, and firearm hobbyists, etc.

This study is led by Primary Investigator Ward R. Drennan, PhD., and takes place at the Virginia Merrill Bloedel Hearing Research Center, located just south of the University of Washington Medical Center. Participation involves 4 sessions total, lasting 2 to 4 hours in length. After the initial 2 study sessions, participants will be asked to return 12-24 months later for the second 2 sessions. At each visit, participants will receive $15 per hour of study time and a voucher for parking reimbursement as a token of our appreciation for participation.
