Hearing Loss clinical trials at UCSD
1 in progress, 0 open to eligible people
Sorry, not yet accepting patients
Fifty adults with mild to moderately severe sensorineural hearing loss will be fit with hearing amplification using two adjustment techniques. For the "audiologist fitting" technique, a licensed audiologist will adjust the hearing device using the standard of care procedures which include adjustment and verification of output to match prescribed targets (NAL-NL2) and subsequent fine tuning to optimize adjustments based on participant feedback. The second technique is "user-adjustment" of the device consisting of adjustment to overall level, high-frequency boost, and low-frequency cut by the participant while listening to speech. A cross-over design will be used in which half the participants are initially fit using the audiologist technique and the other half are initially fit using the user self-adjustment technique. Following a seven-day field trial, participants will return to the lab and the aids will be reset use the other technique. Participants will be blinded to the condition. During each seven-day field trial, users will have access to a volume control, Following the end of the two trials, participants will return to the lab for outcome assessment.
