Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Part 2. Suitability and Acceptability. You will be asked to respond to a short structured interview about the device. If the device has reached a wearable stage, you will wear it outside the laboratory while engaging in discussion with one of the researchers before completing the interview. The goal is to obtain the opinions of persons with hearing loss about the device itself, and about their willingness to wear it as a hearing aid in their everyday life, if they were to be involved in a research study.
Part 3 is a focus-group session with about 10 hearing-aid users, some of whom will have participated in Parts 1 and 2. Topics will deal with hearing aids in general and about the current version of the experimental device. Discussion will be recorded for later transcription and analysis. The goal is to gain the perspective of hearing-aid users about hearing aids, hearing-aid research, and the acceptability of this experimental device for field research.

Study Groups

Exploratory use
Brief (2 hour) exploratory use of prototype self-adjusted wearable Master Hearing Aid
Exploratory use
Participants will be accompanied by a researcher while wearing the open-source speech processing platform as a hearing aid - adjusted to their needs using a widely accepted Fitting prescription. Using a hand-held controller, they will readjust to their liking as the acoustic conditions change. After returning to the laboratory, they will complete speech perception tests using under their self-selected amplification conditions and respond to a structured interview dealing with perceived performance of the device and its acceptability as a hearing aid during possible field studies.
