Abstract

A hearing aid with a communication circuit for wireless communication, the circuit includes a receiver for reception of data, and a communication controller that is configured for determining a delay between a receiver activation and an actual start of reception of data, and adjusting a next receiver activation in accordance with the determined delay.

Claims

1. A hearing aid with a communication circuit for wireless communication, the circuit comprising:

a receiver for reception of data; and

a communication controller that is configured for

determining a delay between a receiver activation and an actual start of reception of data, and

adjusting a next receiver activation in accordance with the determined delay.

2. The hearing aid according to claim 1, wherein the communication controller is configured to adjust the next receiver activation in accordance with a target delay.

3. The hearing aid according to claim 2, wherein the communication controller is configured to adjust the next receiver activation in accordance with previous adjustments and previous determined delays between respective previous receiver activation and previous actual start of reception of data.

4. The hearing aid according to claim 2, wherein the communication controller is configured to adjust the next receiver activation in accordance with previous adjustments or previous determined delays between respective previous receiver activation and previous actual start of reception of data.

5. The hearing aid according to claim 1, wherein the communication controller is configured to adjust the next receiver activation in accordance with previous adjustments and previous determined delays between respective previous receiver activation and previous actual start of reception of data.

6. The hearing aid according to claim 1, wherein the communication controller is configured to adjust the next receiver activation in accordance with previous adjustments or previous determined delays between respective previous receiver activation and previous actual start of reception of data.

7. The hearing aid according to any of the claims 1-6, wherein the communication controller further comprises an oscillator and a counter, the oscillator is configured for providing a clock signal to a timer, and the timer is configured for activating the receiver at a specific count value, and wherein the communication controller is further configured to adjust the count value by an amount corresponding to the determined delay between the receiver activation and the actual start of reception of data.

8. The hearing aid according to any of the claims 1-6, wherein the communication controller further comprises an oscillator and a counter, the oscillator is configured for providing a clock signal to a timer, and the timer is configured for activating the receiver at a specific count value, and wherein the communication controller is further configured to adjust a frequency of the oscillator in accordance with the determined delay between the receiver activation and the actual start of reception of data.

9. The hearing aid according to any of the claims 1-6, wherein the communication controller further comprises an oscillator and a counter, the oscillator is configured for providing a clock signal to a timer by division of one of its output signals, and the timer is configured for activating the receiver at a specific count value, and wherein the communication controller is further configured to adjust a ratio of the division in accordance with the determined delay between the receiver activation and the actual start of reception of data.
