Brief Summary
Speech intelligibility in noise will be evaluated in adults with moderate to moderate-severe sensorineural hearing loss, using an assistive listening device and hearing aid, and compared to speech intelligibility in noise using hearing aids alone.

Outcome Measures
Primary Outcomes (1)
Speech Intelligibility in Noise
The percent of correctly repeated words, when a list of 10 sentences is presented in noise. Ten sentences are presented at a certain loudness level while background noise is presented simultaneously at a specific loudness level. The number of words repeated correctly is calculated from the total number of words presented.

Study Arms (1)
Experimental
EXPERIMENTALParticipants with bilateral moderate to severe sensorineural hearing loss
Interventions
Commercially available transmitter microphone which sends distant speech signals to a receiver that is attached/embedded into hearing aids.

- good written and spoken English language skills
- healthy outer ear as confirmed by otoscopy
You may not qualify if:
- contradictions to medical device noted upon otoscopy
- known hypersensitivity or allergy to materials of investigational device or comparator
