Hearing device
The present disclosure relates to a hearing device comprising a first radar sensor configured for obtaining first radar data indicative of a shape of a first pinna of the first ear of a user. A processing unit of the hearing device is configured to receive the first radar data from the first radar sensor, and determine, based on the first radar data, a shape of the first pinna.
1. A hearing device, comprising:
a first housing configured to be worn at and/or in a first ear of a user;
a processing unit configured to control functionality of the hearing device;
a first radar sensor configured to emit electromagnetic waves to obtain first radar data indicative of a shape of a first pinna of the first ear,
wherein the first radar sensor comprises a phased array, and
wherein the processing unit is further configured to:
receive the first radar data from the first radar sensor,
determine, based on the received first radar data, a shape of the first pinna,
output the shape of the first pinna, and
control a phase relation of antennas within the phased array to scan a user wearing the hearing device.
2. A hearing device according to claim 1 , wherein the processing unit is further configured to:
compare the received first radar data with a prerecorded library of pinna shapes, and
based on the comparison, determine the shape of the first pinna.
3. A hearing device according to claim 1 , wherein the processing unit is further configured to:
perform a calibration process, based on the determined shape of the first pinna.
4. A hearing device according to claim 1 , wherein the phased array comprises at least four antennas.
5. A hearing device, comprising:
a first housing configured to be worn at and/or in a first ear of a user;
a processing unit configured to control functionality of the hearing device;
a first radar sensor configured to emit electromagnetic waves to obtain first radar data indicative of a shape of a first pinna of the first ear, and
wherein the processing unit is further configured to:
receive the first radar data from the first radar sensor,
determine, based on the received first radar data, a shape of the first pinna,
output the shape of the first pinna, and
based on the determined shape of the first pinna, determine a pinna related transfer function, PRTF, for the first ear,
receive orientation data from the orientation sensor,
based on the received orientation data, determine a head orientation of the user, and
based on the determined PRTF and the determined head orientation, determine a head related transfer function, HRTF.
6. A hearing device according to claim 1 , wherein the processing unit is further configured to:
receive an audio signal, and
process the received audio signal based on the determined shape of the first pinna.
7. A hearing device according to claim 1 ,
wherein the hearing device further comprises:
a second housing configured to be worn at and/or in a second ear of a user, and
a second radar sensor connected to the second housing and configured to obtain second radar data indicative of a second pinna of the second ear, and
wherein the processing unit is further configured to:
receive the second radar data from the second radar sensor, and
determine, based on the received second radar data, a shape of the second pinna.
8. A hearing device according to claim 1 , wherein the hearing device is a headset, one or more earbuds, or a hearing aid.
9. A hearing device according to claim 1 , wherein the first radar sensor is configured to emit a radio signal at a frequency of 55 GHz-65 GHz.
10. A hearing device according to claim 1 , wherein the first radar sensor is configured to emit a radio signal at a frequency of 50 GHz-100 GHz.
11. A hearing device according to claim 1 , wherein the first radar sensor is configured to emit a radio signal at a frequency of 40 GHz-120 GHz.
12. A hearing device according to claim 5 , wherein the processing unit is further configured to:
perform a calibration process, based on the determined shape of the first pinna.
13. A hearing device according to claim 4 ,
wherein the hearing device further comprises:
a second housing configured to be worn at and/or in a second ear of a user, and
a second radar sensor connected to the second housing and configured to obtain second radar data indicative of a second pinna of the second ear, and
wherein the processing unit is further configured to:
receive the second radar data from the second radar sensor, and
determine, based on the received second radar data, a shape of the second pinna.
