Abstract
Objectives: Performance of an abutment-level superpower sound processor for bone-anchored hearing, the Ponto 3 SuperPower from Oticon Medical (BCD2), was compared to an earlier model from Oticon Medical (BCD1). Design: A comparative study in which each patient serves as its own control. Setting: Tertiary clinic. Participants: Eighteen experienced BCD1 users with profound mixed hearing loss. Main outcome measures: Speech reception thresholds in noise; APHAB and SSQ questionnaires. Results: In a group of 18 patients with severe mixed hearing loss, the performance of a recently introduced bone conduction device (BCD2) is evaluated relative to that of an earlier model (BCD1). Speech reception thresholds for the sentence-in-noise test in the speech and noise frontal condition are not significantly different (P >.05) for BCD1 and BCD2. Speech reception thresholds for frontal speech and three identical noise sources are 1.7 dB lower for BCD2 than for BCD1 (P .05). Scores for the speech, spatial and quality of hearing domains of the SSQ questionnaire are significantly higher (P
