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 coupling, the iHear MatriX showed mixed results in our lab testing. Speech in quiet scored below average at 1.80/5, while speech in noise performed better at 1.60/5—still modest but above the category baseline. The device excelled in feedback handling with a perfect 5.0/5 score and delivered above-average own voice comfort at 2.70/5, suggesting the power dome provides reasonable occlusion control. The overall initial fit score of 2.08/5 fell below average, indicating the out-of-box experience may require adjustment for optimal performance.
What is HearAdvisor's Initial Fit?
The Initial Fit approximates the most likely settings and eartips for a typical moderate hearing loss. Results are measured across the same 72 acoustic scenes in our custom-built lab, then scored on a 5-star scale using an auditory model.
