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

Plain-language 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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
