A noise-cancelling system includes headset for generating a feedback signal for noise-cancellation in response to sound externally generated from the headset. An encoded microphone signal is generated in response to the first feedback signal. An audio generator can be used to generate a noise-cancellation signal in response to the encoded microphone signal and to generate an electronic audio signal in response to the encoded microphone signal and a first output audio signal. An audio connector is provided to couple the encoded microphone signal from the headset to the audio generator and to couple the first electronic audio signal to the headset.

Headphone providing fully natural interface are described. According to one aspect of such headphones, the headphones comprises a microphone configured for capturing an ambient sound, a speaker configured for playing audio signals, a command interface configured for receiving one or more external control commands, and a control unit having an ambient sound monitoring function. The control unit captures the ambient sound through the microphone, and automatically causes the headphones to enter an interactive mode when a preset interested sound is detected to appear in the ambient sound. The control unit controls the headphones to output an interactive reminder in the interactive mode, and the interactive reminder comprises one or more of visual reminders, a tactile reminder and an auditory reminder. Thus, interaction between the user and the ambience can be realized in a fully natural interface manner according to user preferences.

A method and system for reducing ambient noise distraction with an electronic personal display is disclosed. One example determines when the electronic personal display is in reader mode. In addition, ambient noise around the electronic personal display is also detected. Noise cancelling sound waves are generated at the electronic personal display for reducing ambient noise distraction. The noise cancelling sound waves are then output from at least one speaker coupled with the electronic personal display.

A method performed by an audio system comprising a headset. The method sends a playback signal containing user-desired audio content to drive a speaker of the headset that is being worn by a user, receives a microphone signal from a microphone that is arranged to capture sounds within an ambient environment in which the user is located, performs a speech detection algorithm upon the microphone signal to detect speech contained therein, in response to a detection of speech, determines that the user intends to engage in a conversation with a person who is located within the ambient environment, and, in response to determining that the user intends to engage in the conversation, adjusts the playback signal based on the user-desired audio content.

A system comprises automatic noise cancellation circuitry and interface circuitry operable to provide an interface via which a user can configure which sounds said automatic noise cancelling circuitry attempts to cancel and which sounds said automatic noise cancelling circuitry does not attempt to cancel. The interface circuitry may be operable to provide an interface via which a user can select a sound to whitelist or blacklist. The interface circuitry may be operable to provide an interface via which a user can increase or decrease an amount of noise cancellation that is desired. The interface circuitry may be operable to provide an interface via which a user can select from among three or more levels of noise cancellation.

Embodiments of the present disclosure set forth a method of reducing noise in an audio signal. The method includes determining, based on sensor data acquired from a first set of sensors, a first position of a user in an environment. The method also includes acquiring, via the first set of sensors, one or more audio signals associated with sound in the environment and identifying one or more noise elements in the one or more audio signals. The method also includes generating a first directional audio signal based on the one or more noise elements. When the first directional audio signal is outputted by a first speaker, the first speaker produces a first acoustic field that attenuates the one or more noise elements at the first position.

Embodiments of the present application provide a method and system for active noise control, which can meet different needs of different consumers on sound quality of headphones. The method includes: determining an expected noise control curve of performing active noise control on a target object; determining a target filter according to the expected noise control curve and a filter model; and performing noise control processing on an external noise signal using the target filter.

An earphone includes a feedforward microphone located outside ear and a feedback microphone located inside ear. A method for recognizing wind noise of the earphone includes: feedforward microphone signal collected by feedforward microphone and feedback microphone signal collected by feedback microphone are acquired; Fourier transform is performed on feedforward and feedback microphone signals to obtain a feedforward microphone frequency domain signal and a feedback microphone frequency domain signal; inverse feedback filtering processing is performed on the feedback microphone frequency domain signal to obtain an inverse feedback filtering processing result; inverse feedforward filtering processing is performed on the feedforward microphone frequency domain signal and the inverse feedback filtering processing result to obtain an inverse hybrid filtering processing result; and a wind noise recognition result of the earphone is obtained based on an interrelationship between the inverse feedback filtering processing result and the inverse hybrid filtering processing result.

An earphone includes a first microphone located outside an ear and a second microphone located inside the ear. A method for recognizing wind noise of the earphone includes: a first microphone signal collected by the first microphone and a second microphone signal collected by the second microphone are acquired; a first frequency domain filtered signal is obtained based on the first microphone signal and the second microphone signal; and obtaining a wind noise recognition result of the earphone based on coherence between the first microphone signal and the first frequency domain filtered signal.

A hearing device comprising a first earphone with a first driver unit and a second earphone comprising a second driver unit. The headset further comprises a first ambient microphone configured for converting ambient noise to an ambient input signal. A first electric circuitry is configured for receiving the first ambient input sound signal from the ambient microphone and in an ambient mode outputting a first ambient output sound signal of a certain level to the first driver unit. An activation circuit is configured to activate and deactivate the ambient mode for the hearing device. In the ambient mode, the ambient output sound signal is sent to the first driver unit and not the second driver unit.
