Automated sound processor with audio signal feature determination and processing mode adjustment

摘要

A method includes determining a first feature of a first audio signal at a first location in a signal processing path and determining, using the first feature, a first environmental classification of the first signal. Further, the method includes, based on the first environmental classification, enabling, modifying or disabling one or both of a first signal processing mode at the first location and a second signal processing mode at a second location in the signal processing path. The method also includes determining a second feature of a second audio signal at the second location and determining, using the second feature, a second environmental classification of the second signal. Further, the method includes, based on the second environmental classification, enabling, modifying or disabling one or both of the first signal processing mode at the first location and the second signal processing mode at the second location.

1. A method for controlling a hearing system comprising:
determining a first feature of a first signal at a first location in a signal processing path, wherein the first signal represents a first audio signal; determining, using the first feature, a first environmental classification of a sound environment of the first audio signal; based on the first environmental classification, enabling, modifying or disabling one or both of a first audio signal processing mode at the first location in the signal processing path and a second audio signal processing mode at a second location in the signal processing path; determining a second feature of a second signal at the second location in the signal processing path, wherein the second signal represents a second audio signal; determining, using the second feature, a second environmental classification of a sound environment of the second audio signal; based on the second environmental classification, enabling, modifying or disabling one or both of the first audio signal processing mode at the first location in the signal processing path and the second audio signal processing mode at the second location in the signal processing path; receiving a third audio signal from a first input to the hearing system; receiving a fourth audio signal from a second input to the hearing system; and analyzing the third and fourth audio signals to determine a front directional signal and a rear directional signal, wherein the first audio signal comprises the front directional signal and the second audio signal comprises the rear directional signal.
