| 20090262948 | HEARING AID AND METHOD FOR OPERATING A HEARING AID - The invention relates to a hearing aid comprising at least one signal processing device, at least one counter for detecting discreet events or operating processes, and at least one memory for storing the values or states of the counter, and the threshold values associated with each counter. The hearing aid is also provided with a signal transmitter that is actively connected to the signal processing device in such a way that the signal transmitter is activated when a threshold value of a counter is reached or exceeded. In this way, advantageously, any countable pre-defined events or operating processes can be used to establish and maintain the operating state of the hearing aid. An operating process can be, for example, the variation of a defined operating state of the hearing aid. If a predetermined threshold value is reached, i.e. the number of events reaches this threshold value, a corresponding signal can be triggered and produced by the signal transmitter. | 10-22-2009 |
