Fit Performance
Initial and Tuned Results for the iBstone AuraLink
We tested the AuraLink in both its Initial out-of-box configuration and after completing the manufacturer's Tuned fitting process. The summaries below detail how each fit condition performed against prescription targets.
The initial fit uses a tulip dome with the manufacturer's proprietary default settings, achieving a normalized score of 3.6/5. Out of the box, the AuraLink delivers excellent feedback control at 5.0/5 and solid music streaming at 3.6/5. Speech performance is more limited, with speech in quiet at a mixed 2.3/5 and speech in noise at a low 1.0/5, both falling below category averages. Own-voice comfort measured 2.7/5, slightly above the category average but mixed overall.
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.
