Abstract
A hearing aid system and method for processing one of an input magnetic signal, having magnetic information, and at least one acoustic input signal having acoustic information. The system comprises an acoustic sensor for providing the input acoustic signal, a magnetic sensor for providing the input magnetic signal, and a magnetic signal detector for selecting one of the input acoustic signal and the input magnetic signal as an information signal. The magnetic signal detector selects the input magnetic signal as the information signal when a magnetic signal detection process has at least partially analyzed the input magnetic signal to determine if audio information may be present. The hearing aid system further comprises a hearing aid module for processing the information signal and providing an output signal to a user of the hearing aid system.
