Fit Conditions
Initial and Tuned Fit Results for the Silk Charge&Go IX
The fit summary cards below display performance data for both the Initial factory configuration and the professionally Tuned setting. Toggle between conditions to compare how audiologist adjustments affected measured outcomes.
In the initial fit configuration using sleeve vented coupling, the Silk Charge&Go IX achieved a normalized Initial Score of 3.5/5. Speech in quiet measured 2.9/5 and speech in noise 1.3/5—both below the tuned results. Own-voice comfort performed better in this configuration at 3.6/5, likely reflecting the more open coupling. Feedback handling was strong at 4.6/5. Music streaming registered 0.0/5, indicating no functional streaming capability in this fit.
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.
