摘要： 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.

摘要： A web-based virtual meeting platform with echo suppression functionality that is hardware agnostic. The platform is configured in a client-server distributed architecture, wherein a plurality of user devices are connected to a server. A baseline for audio generated by a user device on the client-side of the client-server platform is established. Upon detection of a deviation from the baseline, including electro acoustic feedback and ambient noise, suppressive gain is applied to the audio input at the client-side of the client-server architecture. The suppressed audio stream is then transmitted to a cloud server and distributed to a plurality of user devices connected to the cloud service. The platform is accessible via an internet browser and is non-discriminatory as to the hardware of the device used to access the platform. Further, the platform does not distribute data in a peer-to-peer architecture.

摘要： Embodiments of the present disclosure disclose an earphone including a fixing structure, a first microphone array, a processor, and a speaker. The fixing structure is configured to fix the earphone near a user's ear without blocking the user's ear canal and including a hook-shaped component and a body part. The first microphone array is located in the body part and is configured to pick up environmental noise. The processor is located in the hook-shaped component or the body part and is configured to estimate a sound field at a target spatial position using the first microphone array and generate a noise reduction signal based on the estimated sound field. The target spatial position is closer to the user's ear canal than any microphone in the first microphone array. The speaker is located in the body part and is configured to output a target signal according to the noise reduction signal.

摘要： A noise cancellation system comprising an audio identification unit configured to identify audio to which a noise cancellation process is to be applied, an output generation unit configured to generate one or more noise cancellation signals in dependence upon the identified audio, and two or more audio output units each configured to reproduce a respective subset of the generated one or more noise cancellation signals, such that the two or more audio output units are configured to produce different outputs.

摘要： A sound system and a method for noise cancellation in a room is provided, the method comprising arranging a set of microphones at a distance from an opening in a wall of the room for provision of one or more microphone input signals including a first microphone input signal; arranging a set of speakers in a vicinity of the opening; determining, based on at least the first microphone input signal, one or more output signals for the set of speakers for matching of sound entering the room through the opening; generating the one or more output signals; and outputting sound signals based on the one or more output signals with the set of speakers.

摘要： Active noise cancellation systems and methods include a feedforward path configured to receive a reference signal comprising ambient noise and adaptively generate an anti-noise signal to cancel the ambient noise. The adaptive filter is tuned in accordance with at least one parameter, which is set by a logic device configured to determine an ambient noise condition based the reference signal by estimating a fullband power of the reference signal, estimating a low-frequency power of the reference signal, comparing the fullband power and low-frequency power to one or more thresholds, and/or setting one or more ambient noise flags. The ambient noise condition may include a quiet background, a wideband noise condition, and/or a low-frequency dominant noise condition.

摘要： 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.
