Abstract

A method for evaluating an individual hearing benefit of an advanced hearing device feature, including providing a basic and an advanced hearing device feature in a hearing device, automatically classifying a current hearing situation, automatically selecting the advanced hearing device feature dependent on the classified hearing situation, applying the selected advanced hearing device feature for processing an audio signal, providing the processed audio signal to an output transducer of the hearing device, indicating to the user that the advanced hearing device feature is currently being applied, and providing a control for the user to switch off and on an effect of the second hearing device feature.

Claims

1. A method for evaluating an individual hearing benefit of a hearing device feature, comprising:

a) providing at least one first, basic hearing device feature in a hearing device;

b) providing at least one second, advanced hearing device feature in the hearing device;

c) automatically classifying a current hearing situation;

d) automatically selecting the at least one second hearing device feature dependent on the classified hearing situation;

e) applying the selected at least one second hearing device feature for processing an audio signal;

f) providing the processed audio signal to an output transducer of the hearing device;

g) indicating to the user that the at least one second hearing device feature is currently being applied; and

h) providing control means for the user to switch off and on an effect of the at least one second hearing device feature.

2. The method of claim 1, wherein at least one of:

indicating that the at least one second hearing device feature is currently being applied;

the control means for switching off and on an effect of the at least one second hearing device feature,

is provided to the user by means of a separate, auxiliary device, such as for instance a remote control unit or a smartphone.

3. The method of claim 1, wherein classifying the current hearing situation comprises determining different sound types and/or determining different connectivity settings, such as for instance determining whether the audio signal is derived from at least one microphone of the hearing device and/or from a signal received by the hearing device.

4. The method of claim 1, further comprising requesting from the user a response indicative of the individual hearing benefit provided by the at least one second hearing device feature to the user.

5. The method of claim 4, wherein as part of the step of requesting, the user is provided with one or more questions, for instance via a display on the auxiliary device or via the output transducer of the hearing device.

6. The method of claim 5, wherein the auxiliary device monitors the current hearing situation, for instance based on a sound signal pick-up by the at least one microphone of the hearing device or a microphone located at the auxiliary device.

7. The method of claim 1, further comprising determining if it is potentially disturbing to provide an indication to the user if the at least one second hearing device feature has been selected, based on information, such as the number of responses already provided by the user indicative of the individual hearing benefit provided by the at least one second hearing device feature, the time of day, calendar data, motion activity data, a circadian rhythm, or a biorhythm, in particular available to and/or determined by the auxiliary device, and not providing the indication to the user if it has been determined to be potentially disturbing.

8. The method of claim 4, wherein as part of responding, the user inputs data into the hearing device or the auxiliary device, e.g. via a user interface, or provides a voice input, which is for instance picked-up by the microphone of the hearing device or a microphone of the auxiliary device.

9. The method of claim 4, wherein the user response is stored as user response data in the hearing device or in the auxiliary device or transferred from the auxiliary device to a remote storage device such as a server, for instance cloud storage.

10. The method of claim 9, further comprising retrieving the user response data stored during initially operating the hearing device, for instance from the hearing device or the auxiliary device or the remote storage device, by a fitting software or a client management software or a web application or an app running on the auxiliary device, such as an app for a smartphone.

11. The method of claim 4, further comprising, in particular as part of a further fitting process, at least one of:

presenting an overview of the user response data stored during initially operating the hearing device;

analysing the user response data stored during initially operating the hearing device;

interpreting the user response data stored during initially operating the hearing device;

determining an individual hearing benefit for the at least one second hearing device feature from the user response data associated with the at least one second hearing device feature from the user response data stored during initially operating the hearing device.

12. The method of claim 11, further comprising configuring the hearing device such that the at least one second, advanced hearing device feature is permanently removed or permanently deactivated or is made permanently available.

13. The method of claim 12, wherein configuring the hearing device is dependent on at least one of:

the determined individual hearing benefit for the at least one second, advanced hearing device feature;

a selection of the at least one second hearing device feature by an audiologist or the user of the hearing device, for instance in a fitting software or a client management software or a web application or an app running on the auxiliary device, such as an app for a smartphone;

performing a financial transaction, for instance by the user;

providing a passkey or an activation code to the hearing device.

14. The method of claim 1, wherein the method is part of a self-fitting or of an online fitting process.

15. The method of claim 1, wherein

the at least one second, advanced hearing device feature comprises one of:

highly directive and/or adaptive beamforming;

adaptive noise cancelling;

wind noise cancelling;

automatic occlusion cancelling;

frequency transposition/compression;

binaural processing, wherein the hearing device is worn at a left ear and a second hearing device is worn at a right ear of the user, such as;

providing the sound of a remote talker, e.g. originating from a far-end telephone, to the left and the right ear of the user;

binaural wind noise cancelling;

automatic listening, e.g. beamsteering, to the side or back when a relevant talker is detected there;

providing many different, e.g. more than 3, automatically selectable hearing programs or signal processing configurations) adapted for many different, e.g. more than 3, sound types or classes;

audio streaming of at least one of a telephone, a television, a media player, a public address, and an alarm signal to the hearing device.
