Abstract:
Personal audio systems and methods are disclosed. A personal audio system includes a voice activity detector to determine whether or not an ambient audio stream contains voice activity, a pitch estimator to determine a frequency of a fundamental component of an annoyance noise contained in the ambient audio stream, and a filter bank to attenuate the fundamental component and at least one harmonic component of the annoyance noise to generate a personal audio stream. The filter bank implements a first filter function when the ambient audio stream does not contain voice activity, or a second filter function when the ambient audio stream contains voice activity.

Claim (Index 1):
A personal audio system, comprising:\n a processor coupled to an active acoustic filter configured to receive an ambient audio stream, the processor is configured to:\n determine a current context of a user associated with the personal audio system; \n retrieve one or more candidate annoyance noise classes from a sound database based on the determined current context; \n configure a first filter function to identify a set of expected annoyance noises based on the retrieved one or more candidate annoyance noise classes; \n determine a frequency of a fundamental component of an annoyance noise contained in the ambient audio stream, wherein the annoyance noise is one of the set of expected annoyance noises and corresponds to a specific source; \n implement the first filter function when the ambient audio stream does not contain voice activity, wherein the first filter function is configured to attenuate the fundamental component and at least one harmonic component of the annoyance noise; and \n implement a second filter function, different from the first filter function, when the ambient audio stream contains voice activity, wherein the second filter function is configured to attenuate the annoyance noise in one or more frequency bands that the annoyance noise overlaps with a voice associated with the voice activity; and \n a memory coupled to the processor and configured to provide the processor with instructions.
