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.
Recording with hearing aid
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.
Recording with hearing aid
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.
