Fit Conditions
Oticon Zeal Test Results Across Initial and Tuned Settings
The Oticon Zeal was measured in both Initial and Tuned fit conditions to capture performance before and after professional adjustment. Select either condition below to view the corresponding lab results.
In initial fit testing with a closed vented dome and NAL-NL2 fitting formula, the Oticon Zeal achieved a normalized score of 4.2/5. Speech in quiet performed well at 3.9/5, while speech in noise measured 2.0/5. Music streaming was a highlight at 4.1/5, and feedback handling was solid at 3.8/5. Own voice comfort scored 2.0/5, reflecting the challenges typical of more occluding coupling styles. This initial configuration provides strong out-of-box performance, particularly for speech clarity and media consumption.
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.
