METHOD FOR FOLLOWING A SOUND SOURCE, AND HEARING AID DEVICE

摘要

A method of following a sound source with a hearing aid device. The hearing aid device has a plurality of microphones, a monitoring device, a locating device, a directional device, an energy source, a controller and an electro-mechanical transducer. The directional device generates a signal with a variable directional characteristic from the microphone signals. The directional signal is monitored for an incipient acoustic signal from a sound source from a predetermined direction range. The locating device determines the direction of origin of the sound source. A predetermined directional characteristic with an orientation toward the first sound source is also set in the directional device. The locating device then determines a change in the direction of origin of the first sound source and the orientation of the directional characteristic is set based on the changed direction of origin in the directional device.

主权项

1. A method for following a sound source with a hearing aid device, the method comprising:
providing the hearing aid device with a plurality of microphones, a monitor for monitoring a signal, a locator for determining a direction of origin of the sound source, a director for generating a directional characteristic, an energy source, a controller and an electro-mechanical transducer, the director being configured to receive a plurality of first signals with acoustic information from the plurality of microphones and to process the plurality of signals to form a second signal with a variable directional characteristic; a) monitoring the second signal for an incipient acoustic signal from a first sound source from a predetermined direction range relative to the hearing aid device using the monitor; b) determining a direction of origin of the first sound source relative to the hearing aid device using the locator, c) setting a predetermined directional characteristic with an orientation toward the first sound source using the controller in the director; d) determining a change in the direction of origin of the first sound source relative to the hearing aid device using the locator; and e) changing an orientation of the predetermined directional characteristic to the changed direction of origin of the first sound source relative to the hearing aid device in the director using the controller.
