Investigating the DNN Noise Reduction Feature in Phonak Hearing Aids Using Ecological Momentary Assessment

Participants will undergo a hearing aid fitting for both the Phonak device and the Competitor device A. In the lab, participants will be seated in the center of a 10-speaker array. Diffuse ecologically valid noise will be coming from all 10 speakers, while recorded sentences will be presented one at a time randomly from 4 speakers in front of the participant. Participants will be given two lists of 25 sentences for each hearing aid condition, and will repeat as many words as they can. Percentage correct will be calculated for each hearing aid condition. The second appointment will consist of a real-world visit to a local cafe, in which they will be seated at a table with three other conversation partners. During the cafe visit, participants will be asked to answer questions about their perceived speech clarity, ease of listening, and listening confidence with each of the two devices. Participants will be blinded as to which devices they are wearing for both the lab visit and the real world cafe visit.
