Summary
In the initial fit condition using a power dome with slits, the Otofonix Elite performed well below average across nearly all metrics. Speech in quiet (-0.30/5) and speech in noise (-0.70/5) scores indicate limited benefit for understanding conversation. Own-voice comfort was poor at 1.30/5, suggesting noticeable occlusion. Feedback handling was the sole strong point at 5.00/5, meaning the device remained stable without whistling. The open coupling likely contributed to the feedback stability but was insufficient to deliver adequate amplification for the target hearing loss profile.
Switching to a closed dome in the tuned fit condition did not improve performance—in fact, scores declined. Speech in quiet dropped further to -1.50/5, and own-voice comfort fell dramatically to 0.10/5 as the more occluding coupling worsened the occlusion effect. Speech in noise remained poor at -0.80/5. While feedback handling stayed excellent at 5.00/5, the overall fit score decreased by 0.62 points compared to initial fit. This unusual pattern suggests the device lacks the gain and processing sophistication to benefit from more occluding coupling.
