1. A method of determining an interference value, the method comprising:
- providing a sound signal;
providing an interferer signal;
establishing a pair of a first portion of the sound signal and a second portion of the interferer signal, the first and second portions having a particular time duration;
determining a single value of a first sound energy of the first portion;
determining a single value of a second sound energy of the second portion;
determining a single value of a third sound energy of a combination of the first and second portions; and
determining the interference value based on one single value of the single values of the first, second and third sound energies,wherein the establishing, the determining the first sound energy, the determining the second sound energy, the determining the third sound energy, and the determining the interference value are performed within a period of time that is less than the particular time duration.

Abstract
A method and a system for determining an interference value. The method receives a sound signal and an interferer signal and forms a pair of a portion of the sound signal and the interferer signal. The portions have a predetermined time duration but the method is capable of determining the interference value swifter, so that the interference value may be output in real time.

12. A system for determining an interference value, the system comprising:
-
a first input configured to receive a sound signal; a second input configured to receive an interferer signal; a first processor configured to establish a pair of a first portion of the sound signal and a second portion of the interferer signal, the first and second portions having a particular time duration; a second processor configured to determine a single value of a first sound energy of the first portion; a third processor configured to determine a single value of a second sound energy of the second portion; a fourth processor configured to determine a single value of a third sound energy of a combination of the first and second portions; and a fifth processor configured to determine the interference value based on the single values of the first, second and third sound energies, wherein the establishing, the determining the first sound energy, the determining the second sound energy, the determining the third sound energy, and the determining the interference value are performed within a period of time that is less than the particular time duration. - View Dependent Claims (13, 14, 15)
