Clinical Evaluation of Hearing Aid OTC Self-Assessment Methods for Adults With Perceived Mild-to-Moderate Hearing Loss
Starting soon · Not applicable
Conditions studied: Sensorineural Hearing Loss, Perceived Hearing Loss, Hearing Impairment
In brief
The goal of this clinical trial is to compare two methods of self assessment of hearing with conventional audiometry in an OTC Hearing Aid for adults with perceived mild to moderate hearing loss. The main questions it aims to answer are: 1. To evaluate agreement between prescribed gain outputs generated from conventional audiometry and those generated from the self-assessment response method. 2. Determine whether either self-assessment response method provides acceptable estimated audibility. 3. Evaluate participant preference between the detection response method and the audibility-release response method. Researchers will compare the two novel methods with conventional audiometry to determine levels of agreement. Participants will self assess their hearing methods using two novel methods of hearing assessment as well as receive a conventional audiometric evaluation of hearing levels.
