The Hear Clear Study
Sponsor: Duke University
Summary
The purpose of this study is to determine if hearing aid use helps adults with "normal" hearing on clinical hearing tests (i.e., pure-tone audiogram), but who report hearing trouble in everyday life. Another purpose is to understand what factors and hearing aid features provide the most help for these people.

Conditions
Interventions
Signal-to-Noise Ratio Enhancement (SNR+)
Participants will be randomly assigned to either the open dome or closed dome group (Factor 1). Participants will then obtain their first treatment arm with a random assignment of either an SNR neutral (SNR-) or SNR enhanced (SNR+) hearing aid fitting (Factor 2). They will return to the lab for testing prior to crossing over to the second arm (the other SNR configuration: SNR- or SNR+). The SNR+ setting contains features to improve the signal-to-noise ratio of the sound to optimize speech over noise through the hearing aids.
Signal-to-Noise Ratio Neutral (SNR-)
Participants will be randomly assigned to either the open dome or closed dome group (Factor 1). Participants will then obtain their first treatment arm with a random assignment of either an SNR neutral (SNR-) or SNR enhanced (SNR+) hearing aid fitting (Factor 2). They will return to the lab for unaided baseline testing prior to crossing over to the second arm (the other SNR configuration: SNR- or SNR+). The SNR- setting contains focuses on improving audibility of sounds through the hearing aids.
