Abstract
A method for monitoring the supply voltage of a hearing aid comprising an electric cell () comprises the steps of counting the number of times the supply voltage falls below a predetermined value, and setting an alarm flag if said number of times reaches a predetermined value. The method may be implemented using a circuit for monitoring the supply voltage of an electric cell. The circuit comprises a timer timing a detection interval, a detector for detecting drops in the voltage below a predetermined threshold value, a counter for counting the number of detections within said detecting interval, means () for setting an alarm flag if said number of times reaches a predetermined value within said first detection interval, and means () for suspending alarms during warm-up phase.
