Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The stimuli consist of speech in quiet, speech in noise, reverberant speech, and music recorded with different hearing aid settings, post-processed for headphone presentation and incorporated in an online sound survey. Participants will receive tablets and headphones to conduct a sound quality rating at home. The survey will involve a training session and within-subject repeated measures. Stimuli presentation will be randomized by sound quality rating tool.

Participants Investigators
The acoustic output of the different devices had been recorded and the recordings have been presented in random order (random order created by the sound survey algorithm) to the participants in a digital sound survey, so neither the researcher nor the participant knew which recording the participant was listening to when rating.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hearing aid 1 default amplification strategy

Hearing aid 1 default amplification strategy: A receiver-in-canal (RIC) hearing aid developed by the study sponsor used with the default settings as specified in the study sponsor's fitting software.

Group Type EXPERIMENTAL

Recording with hearing aid

Intervention Type DEVICE

Each participant will listen to sound samples via headphones. Sound samples have been recorded with a hearing aid that was set to each participant's individual hearing loss and different amplification strategies, and an unaided reference. Participants will be asked to rate different aspects of sound quality while listening to the different sound samples.

Hearing aid 2

Hearing aid 2: A receiver-in-canal (RIC) hearing aid developed by the another hearing aid manufacturer used with the default settings as specified in the manufacturer's fitting software.

Group Type EXPERIMENTAL

Recording with hearing aid

Intervention Type DEVICE

Each participant will listen to sound samples via headphones. Sound samples have been recorded with a hearing aid that was set to each participant's individual hearing loss and different amplification strategies, and an unaided reference. Participants will be asked to rate different aspects of sound quality while listening to the different sound samples.

Hearing aid 1 strategy 1

Hearing aid 1 strategy 1: A receiver-in-canal (RIC) hearing aid developed by the study sponsor used with a modified compression strategy that is expected to improve sound quality.
