Fit Conditions
Cearvol Wave Results Across Initial and Tuned Settings
We tested the Cearvol Wave in both its out-of-box Initial configuration and after Tuned optimization. Toggle between conditions below to compare how each setup performed against prescriptive targets.
Out of the box with a Power Dome coupling and proprietary fitting, the Cearvol Wave achieves a normalized Initial Score of 3.9/5. Speech in quiet performs solidly at 3.0/5, while speech in noise is more limited at 1.9/5. Music streaming is a clear strength at 4.1/5, delivering strong fidelity for phone-streamed audio. Own-voice comfort scores 2.1/5, indicating some potential for occlusion-related discomfort. Feedback handling is solid at 3.8/5, maintaining stability during typical use.
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.
Performance Metrics
Cearvol Wave Scores Across Five Lab Measurements
Our testing protocol evaluates five distinct performance dimensions using calibrated equipment and standardized procedures. The score card below shows how the Cearvol Wave measured on speech in quiet, speech in noise, own voice, feedback management, and music streaming.
Amplification Analysis
Cearvol Wave Insertion Gain Versus Prescriptive Targets
Real-ear insertion gain measurements reveal how closely a hearing aid matches evidence-based amplification prescriptions. The graph below plots the Cearvol Wave's measured output against target curves across the frequency spectrum.
Audio Samples
Hear the Cearvol Wave Through Manikin Recordings
We capture audio through a head-and-torso simulator fitted with the hearing aid under test conditions. Compare the Cearvol Wave recordings below against our unaided reference to hear measured differences in amplification and sound quality.
