Abstract
The invention concerns a hearing device having an input transducer and an output transducer with a signal path therebetween, signal processing means connected in said signal path for influencing a signal in the signal path dependent on a PPS (processing parameter set), and a PPS memory accessible by the signal processor means for storing a number of different PPS's for use by the signal processing means. The system has means for monitoring the acoustic environment in a learning mode, where the user chooses the PPS to be used in the signal processing. Later in an automatic mode the hearing aid system chooses the PPS based on a comparison of the current acoustic environment with the monitored environment in the learning phase.
Claims17
A hearing device comprising:
- a programmable hearing aid having an input transducer and an output transducer with a signal path therebetween, signal processing means connected in said signal path for influencing a signal in the signal path dependent on a PPS or processing parameter set, and a PPS memory accessible by the signal processor means for storing a number of different PPS's for use by the signal processing means,
- user input means for the user to choose a specific PPS to be used by the signal processing means in manual mode whenever the user experiences a specific acoustic environment,
- means for capturing and storing in a second memory of CAV's or characterizing acoustic values derived from the signal during use of each of the user chosen PPS during a learning period in the manual mode whereby the means comprises a number of storing places arranged as a second cyclic buffer in the second memory for each of the CAV's for storing consecutively derived values, and storing places in the second memory for storing the most frequently occurring value of each CAV in the cyclic buffer,
- means for capturing and temporarily storing in a first memory of current CAV in an automatic mode,
- means for automatic selection of a PPS in an automatic mode, whereby the automatic selection is based on the comparison between current CAV's stored in the first memory and CAV's stored in the second memory.
Method for choosing program in a multi program hearing device, whereby the hearing device has an input transducer and an output transducer with a signal path there between, providing signal processing means connected in said signal path for influencing a signal in the signal path dependent on a PPS or processing parameter set, and providing a PPS memory accessible by the signal processor means and storing a number of different PPS's for use by the signal processing means,
- providing user input means for the user to choose a specific PPS to be used by the signal processing means whenever the user experiences an acoustic environment,
- capturing and storing in a second memory of CAV's or characterizing acoustic values derived from the signal during use of each of the user chosen PPS during the learning period in the manual mode are stored in second cyclic buffer in the second memory and where the most frequently occurring value for each of the CAV's is stored in the second memory,
- capturing and temporarily storing in a first memory of current, CAV's-automatic selection of a PPS, whereby the automatic selection is based on the comparison between current CAV stored in the first memory and CAV's stored in the second memory.
