About the study
Eighteen experienced bone anchored implant patients with mixed hearing losses were the subjects of this comparison study. All test subjects had used their existing device for at least four months. Patients completed objective pure tone and speech testing using a new device to control for the possible effects of long-term use of their own processor. Patients also completed three subjective questionnaires in reference to their current devices: the APHAB, two relevant sections of the SSQ, and proprietary questionnaires. Patients were then asked to spend 3–4 weeks wearing a new Ponto Pro Power sound processor. After this trial period, patients completed the same objective measures and subjective questionnaires in reference to Ponto Pro Power.
