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

Sponsor: Sonova AG

Summary

The goal of this interventional study is to evaluate the DNN Noise reduction feature of Phonak hearing aids in adults with moderate to moderate severe hearing loss. The main questions it aims to answer are: Do participants correctly identify significantly more words on the AZBio Sentence Test when using Phonak's DNN NR feature than when using Competitor device A in a lab setting? Do participants subjectively rate the speech clarity, ease of listening, and listening confidence higher when using Phonak's DNN feature than when using Competitor device A in both a lab setting and a real-world cafe setting? Do participants have an overall preference for the Phonak device over the Competitor device A in a real-world cafe setting? Participants will be fit with both the Phonak device and a Competitor device A in the lab. They will be given the AZBio Sentence test and repeat as many words as they can in a simulated noisy environment. Following the lab visit, participants will meet in a group with three other conversation partners in a real-world setting and asked to complete subjective questionnaires during the visit.
