Interventions

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.
