Integration of the REM-verification within the fitting workflow will enable the hearing care professional to easily run real ear measurements. The purpose of the two study parts is to prove that an integrated cooperative system, consisting of fitting software and measurement system, matches desired responses for certain stimuli faster, more reliably and more precisely at the ear drums of hearing instrument wearers than current best practice processes.

The subjects individual response of the ear canal gets measured with the help of a probe tube and a following hearing aid fitting.
Phonak AG
Stäfa, Canton of Zurich, Switzerland
Distance (mm) from probe tube to eardrum measurement
Precise of the Probe Tube placement
Time frame: 1 month
Procedure time (min) of fitting workflow including Real Ear measurement
In addition to the outcome measurement "time" (in minutes) further outcome measurements can be obtained due to the performed real ear measurement procedure itself. Data that give information pertaining to test reliability (in dB) and precision of hearing aid fitting (in dB).
Time frame: 2 month
Subjective rating of unpleasantness (0 = not unpleasant at all, 10 = very unpleasant)
Pleasantness during the probe tube placement
Time frame: 1 month
Questionnaire about perceived annoyance
Perceived annoyance of the hearing care professional and the test subject measured with a questionnaire including rating scales for stessful and boring.
Time frame: 2 month
