Clinical Study Shows Significant Benefit of Own Voice Processing

This clinical trial suggests that Signia OVP provides a substantial improvement in own-voice satisfaction, and that this improvement is present for different fitting strategies, and for different ear-canal couplings. Specifically, with OVP-Off, 10 of the 21 participants (48%) were not satisfied with their own voice (e.g., rating below #4). With OVP-On, 8 of these 10 individuals (80%) were now satisfied (rating above #4), resulting in a total group satisfaction of 90% (19 out of 21). Moreover, when the satisfaction with OVP is compared to alternative solutions from competitive products, a significant OVP advantage was seen—to the extent that own-voice satisfaction with OVP using a closed fitting is equal or superior to other products using an open fitting.
