Fit Conditions
Initial and Tuned Measurements for the Pure C&G BCT IX
Our lab evaluated this hearing aid under both Initial and Tuned fit conditions. The summary cards below present performance outcomes for each configuration, showing how professional adjustment affected measured results.
In initial fit testing with a vented sleeve coupling and the manufacturer's IXFit formula, the Pure C&G BCT IX achieved a normalized Initial Score of 4.4/5. Speech in quiet started strong at 3.9/5, while speech in noise measured 2.4/5. Own-voice comfort scored 3.8/5, and feedback handling came in at 4.2/5. Music streaming measured 2.5/5. These results suggest solid out-of-box performance with particular strength in speech clarity and own-voice naturalness.
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.
