Abstract
Disclosed herein, among other things, are systems and methods for cancelling interference from a telecoil signal for ear-wearable devices. A method includes receiving a signal from a telecoil of a hearing device, and using a trigger signal to initiate recordings of segments of the telecoil signal. An interference component is isolated from the telecoil signal using the recorded segments. The interference component is inverted and added to the telecoil signal to cancel the interference component from the telecoil signal, and audio from the telecoil signal is provided to a wearer of the hearing device.
Claims20
A method, comprising:
- receiving a signal from a telecoil of a hearing device;
- using a trigger signal to initiate recordings of segments of the telecoil signal;
- isolating an interference component from the telecoil signal using the recorded segments;
- inverting the interference component;
- summing the inverted interference component with the telecoil signal to cancel the interference component from the telecoil signal;
- and
- playing audio from the telecoil signal for a wearer of the hearing device.
A hearing device, comprising:
- a magnetic sensor configured to receive an inductive input;
- and
- at least one processor and data storage in communication with the at least one processor, wherein the data storage comprises instructions thereon that, when executed by the at least one processor, causes the at least one processor to:
- receive a signal from the magnetic sensor;
- use a trigger signal to initiate recordings of segments of the signal;
- isolate an interference component from the signal using the recorded segments;
- invert the interference component;
- sum the inverted interference component with the signal to cancel the interference component from the signal;
- and
- play audio from the signal for a wearer of the hearing device.
