Abstract
A method performed by a first hearing device, includes: determining a first gain value, a second gain value, or both the first and second gain values; generating an intermediate signal including or based on a combination of the first directional input signal and the second directional input signal, wherein the first and second directional input signals in the combination are combined based on the first gain value, the second gain value, or both of the first and second gain values; and generating an output signal for the output unit based on the intermediate signal; wherein one or both of the first gain value and the second gain value are determined in accordance with an objective of making a proportion of the first directional input signal and a proportion of the second directional signal at least substantially equal.
Claims29
A method performed by a first hearing device, the first hearing device comprising a first input unit including one or more microphones and being configured to generate a first directional input signal, a communication unit configured to receive a second directional input signal from a second hearing device, an output unit, and a processor coupled to the first input unit, the communication unit, and the output unit, the method comprising:
- determining a first gain value, a second gain value, or both the first and second gain values;
- generating an intermediate signal including or based on a combination of the first directional input signal and the second directional input signal, wherein the first and second directional input signals in the combination are combined based on the first gain value, the second gain value, or both of the first and second gain values;
- and
- generating an output signal for the output unit based on the intermediate signal;
- wherein one or both of the first gain value and the second gain value are determined in accordance with an objective of making a proportion of the first directional input signal and a proportion of the second directional signal at least substantially equal.
A method performed by a first hearing device, the first hearing device comprising a first input unit including one or more microphones and being configured to generate a first directional input signal, a communication unit configured to receive a second directional input signal from a second hearing device, an output unit, and a processor coupled to the first input unit, the communication unit, and the output unit, the method comprising:
- generating an intermediate signal including or based on a combination of the first directional input signal and the second directional input signal, wherein the first and second directional input signals are combined in the combination based on one or both of a first filter transfer function and a second filter transfer function;
- generating a first power spectrum based on the first directional input signal and the second directional input signal;
- generating a cross power spectrum based on the first directional input signal and the second directional input signal;
- for one or more frequency bands, determining a first value and a second value among an estimated power value of the first directional input signal and an estimated power value of the second directional input signal;
- generating a first filtered signal by filtering the first directional input signal by an equalization filter, or by filtering the second directional input signal by the equalization filter, wherein the equalization filter is based on an algebraic relation between the first value and the second value;
- and
- generating an output signal based on the first filtered signal.
