Summary
In the initial fit condition using a power dome with slits coupling, the RCA Micro performed well below expectations across key metrics. Speech understanding scores were negative in both quiet and noisy conditions, indicating the device provided minimal audibility benefit for our standard hearing loss profile. Own-voice comfort scored below average at 1.60, suggesting noticeable occlusion effects. The one bright spot was feedback handling, which scored a perfect 5.00, meaning the device remained stable without whistling. The overall initial fit score of 0.04 reflects substantial limitations in out-of-box performance.
Switching to a standard power dome in the tuned fit condition did not improve performance—in fact, the overall fit score dropped slightly to -0.16. Speech-in-quiet scores worsened from -1.50 to -2.30, while speech-in-noise remained unchanged at -1.00. Own-voice comfort improved modestly to 2.10 with the more occluding dome. Feedback handling remained excellent at 5.00. The tuned configuration demonstrates that even with coupling adjustments, the RCA Micro's amplification characteristics could not be optimized to deliver meaningful speech benefit in our testing framework.
