HearingAssist Control Expert Review

Quality data starts with quality recordings. HearAdvisor worked with GRAS to build a no-compromise front end so every test is repeatable and reliable.

In the initial fit condition using a power dome with slits, the HearingAssist Control performed below expectations. Speech in quiet scored 1.50/5 and speech in noise scored 1.00/5, both well under category averages. The standout metric was feedback handling at a perfect 5.00/5, indicating excellent stability without whistling. Own-voice comfort measured 2.10/5, reflecting noticeable occlusion effects. The overall initial fit score of 1.72/5 suggests this device requires adjustment beyond the out-of-box setup to deliver adequate speech benefit.
