摘要： In an active noise reducing headphone, a signal processor applies filters and control gains of both the feed-forward and feedback active noise cancellation signal paths. The signal processor is configured to apply first feed-forward filters to the feed-forward signal path and apply first feedback filters to the feedback signal path during a first operating mode providing effective cancellation of ambient sound, and to apply second feed-forward filters to the feed-forward signal path during a second operating mode providing active hear-through of ambient sounds with ambient naturalness.

摘要： A headset includes a microphone for receiving a user's voice, a microphone for receiving ambient noise, a receiver for receiving a plurality of voice signals, a speaker for delivering sound to the user's ear and a processing device. The processing device is configured to identify a signal level of a first one of the plurality of voice signals and a second one of the plurality of voice signals, the signal level of the second voice signal being different than the signal level of the first voice signal. The processing device is also configured to measure the ambient noise level and adjust a gain applied to at least one of the first and second voice signals, taking into consideration the ambient noise level. The first and second voice signals are provided to the speaker.

摘要： A system for combining signals includes a first microphone generating a first input signal having a first voice component and a first noise component, a second microphone generating a second input signal having a second voice component and a second noise component, a mixing circuit, and an adaptive filter. The mixing circuit applies a first gain having a value α to the first input signal to produce a first scaled signal, applies a second gain having a value 1−α to the second input signal to produce a second scaled signal, and sums the first scaled signal and the second scaled signal to produce a summed signal. The adaptive filter computes an updated value of α to minimize the energy of the summed signal based on the summed signal, the first input signal and the second input signal, and provides the updated value of α to the mixing circuit.
