Hearing-aid device with automatic algorithm switching

摘要

The device has a determination device (16) for determining whether one of two microphones (10, 11) is defect. A signal processing device (12) processes signals of the microphones with single-channel and multi-channel processing algorithms (13, 14). The signal processing device is automatically switched from one of the processing algorithms to the other processing algorithm when the defected microphone is detected. A storage device records information about the defected microphone along with time information. A LED indicates an emergency operating condition of the device.
