Abstract:
1. A method implemented on a computer for determining a gain setting for each of at least two different frequency bands of a bone-anchored hearing aid comprising an element, which for each said frequency band has a gain influencing an output level of the hearing aid, and a bone anchor, which is implanted in a bone structure of an individual at a laterally asymmetrical implantation location thereby defining a proximal ear and a distal ear of the individual, the proximal and the distal ear having respective first and second monaural bone-conduction hearing curves, the first monaural bone-conduction hearing curve being higher than the second monaural bone-conduction hearing curve, and the hearing aid being adapted to control the gain of each said frequency band in dependence on a corresponding gain setting, the method comprising for each said frequency band: obtaining respective first and second measured monaural bone-conduction hearing thresholds for the proximal and the distal ear; estimating with a processing unit in dependence on the first and the second measured monaural bone-conduction hearing thresholds whether the proximal ear or the distal ear has a lower implant-specific bone-conduction hearing threshold, thereby defining a more sensitive ear; calculating with said processing unit the corresponding gain setting based on the measured monaural bone-conduction hearing threshold for the more sensitive ear; estimating transcranial attenuation between the implantation location and the cochlea of the distal ear; and transmitting with a communication adapter the corresponding gain setting to the hearing aid.
