METHOD FOR OPERATING A HEARING AID AND HEARING AID

Abstract

A method operates a hearing aid having a housing insertable into an outer auditory canal and has proximal and distal sides. The proximal side is oriented toward an eardrum and includes a proximal input transducer, and a distal input transducer is disposed on the distal side. An output transducer is disposed on the proximal side and an adjustable vent penetrates the housing. An evaluation unit is provided, and an adjustment process is carried out to adjust the vent. In the course of the adjustment process, a set of transmission functions is determined by the evaluation unit, and includes a distal transmission function, which maps a signal path from the output transducer to the distal input transducer, and a proximal transmission function, which maps a signal path from the output transducer to the proximal input transducer.

Description

Claims

1. A method for operating a hearing aid having a housing configured for being inserted into an outer auditory canal and with a proximal side and a distal side opposite to the proximal side, wherein the proximal side is configured to be oriented toward an eardrum and having a proximal input transducer on the proximal side of the housing and a distal input transducer on the distal side of the housing, the hearing aid further having an output transducer on the proximal side of the housing, an adjustable vent which penetrates the housing, and a control and evaluation unit, which comprises the steps of: carrying out an adjustment process to adjust the adjustable vent and wherein in a course of the adjustment process a set of transmission functions is determined by means of the control and evaluation unit, which set includes at least two transmission functions, namely a distal transmission function, which maps a signal path from the output transducer to the distal input transducer, and a proximal transmission function, which maps a signal path from the output transducer to the proximal input transducer.

2. The method according to claim 1, wherein the set of transmission functions includes: a first distal transmission function, which maps a signal path from the output transducer to the distal input transducer with the adjustable vent completely open; anda second distal transmission function, which maps a signal path from the output transducer to the distal input transducer with the adjustable vent completely closed.

3. The method according to claim 1, wherein the set of transmission functions includes: a first proximal transmission function, which maps a signal path from the output transducer to the proximal input transducer with the adjustable vent completely open; anda second proximal transmission function, which maps a signal path from the output transducer to the proximal input transducer with the adjustable vent completely closed.

4. The method according to claim 1, wherein the set of transmission functions includes a distal-proximal transmission function, which maps a signal path from the distal input transducer to the proximal input transducer.

5. The method according to claim 1, wherein the set of transmission functions includes: a first distal-proximal transmission function, which maps a signal path from the distal input transducer to the proximal input transducer with the adjustable vent completely open; anda second distal-proximal transmission function, which maps a signal path from the distal input transducer to the proximal input transducer with the adjustable vent completely closed.

6. The method according to claim 1, wherein: in a course of the adjustment process, a control signal is generated by means of the control and evaluation unit based on the set of transmission functions; andan adjusting device of the adjustable vent is activated by the control signal, so that at least one geometric parameter of the adjustable vent is automatically adjusted by the adjusting device.

7. The method according to claim 6, wherein at least three settings are specifiable by means of the adjusting device of the adjustable vent, namely a setting in which the adjustable vent is completely open, a setting in which the adjustable vent is completely closed, and at least one setting in which the adjustable vent is partially open.

8. The method according to claim 6, wherein a reference function is specified for each transmission function in the set of transmission functions and wherein the control signal is generated in the course of the adjustment process by means of the control and evaluation unit in such a way that the transmission functions approximate reference functions.

9. The method according to claim 8, wherein the adjustment process is configured as a regulating process.

10. The method according to claim 1, which further comprises carrying out a plurality of adjustment processes automatically and wherein time intervals between the adjustment processes are automatically adapted at a power consumption controller.

11. The method according to claim 1, wherein the adjustment process is manually started.

12. A hearing aid configured to execute a method according to claim 1 in at least one operating mode.
