摘要： Noises that are to be emitted by an aerial vehicle during operations may be predicted using one or more machine learning systems, algorithms or techniques. Anti-noises having equal or similar intensities and equal but out-of-phase frequencies may be identified and generated based on the predicted noises, thereby reducing or eliminating the net effect of the noises. The machine learning systems, algorithms or techniques used to predict such noises may be trained using emitted sound pressure levels observed during prior operations of aerial vehicles, as well as environmental conditions, operational characteristics of the aerial vehicles or locations of the aerial vehicles during such prior operations. Anti-noises may be identified and generated based on an overall sound profile of the aerial vehicle, or on individual sounds emitted by the aerial vehicle by discrete sources.

摘要： In an active noise reduction device, in order to solve this problem, a control block determines a level of a reference signal detected by a level detection unit. If determining that the level of the reference signal is small, the control block decreases a level of a cancel signal. This operation suppresses generation of an abnormal sound even if a level of a noise is small.

摘要： A system includes a microphone, a controller, and a speaker. The microphone is configured to detect noise generated by a functional hardware component due to user interaction with the component. The controller is configured to identify the component from the noise and obtain a noise cancelling signal pre-associated with identification of the component. The speaker is configured to output a noise cancelling sound based on the noise cancelling signal whereby the noise is attenuated.

摘要： An electronic device may include a display having an active area and an inactive area. The display may include a cover layer and an array of pixels that emit light through the cover layer in the active area. An opaque masking layer may be formed on an inner surface of the cover layer in the inactive area. A touch sensor may include touch sensor electrodes under the opaque masking layer in the inactive area to detect touches near electronic components that are mounted in the inactive area. Operation of the electronic components may be controlled based on signals from the touch sensor in the inactive area. The touch sensor may be formed from capacitive touch sensor electrodes. The capacitive touch sensor electrodes may be formed on the same substrate as an adjacent electronic component or may be formed as an extension of an existing touch sensor in the display.

摘要： A noise cancellation system generates a noise cancellation signal from a signal representing ambient noise by signal processing. The signal processing applies a controllable gain value, and includes a high pass filter with a controllable cut-off frequency. A control block detects a wind amplitude. The cut-off frequency of the high pass filter is controlled based on the detected wind amplitude. A low pass function is applied to the detected wind amplitude, and the controllable gain is adjusted based on the output of the low pass function.

摘要： [Object] To reduce the influence of noise in a more preferred aspect even in an environment in which a user hears an acoustic sound output to an open space.[Solution] A signal processing device includes: a generation unit configured to generate a first noise reduction signal for driving a first acoustic device which outputs a first acoustic sound for reducing noise; and an acquisition unit configured to acquire a sound collection result of an acoustic sound collected by a predetermined sound collection unit, the acoustic sound including the first acoustic sound propagating from the first acoustic device via a first propagation path and a second acoustic sound propagating from a second acoustic device different from the first acoustic device via a second propagation path. The generation unit generates the first noise reduction signal on a basis of the sound collection result and a cancellation signal based on a second noise reduction signal for driving the second acoustic device.

摘要： Disclosed herein are systems and methods for controlling the noise and sound emitted by an unmanned aerial vehicle. The unmanned aerial vehicle may emit a sound to mask the noise created by the propellers of the vehicle. It may additionally emit sounds based on the information about the area surrounding the vehicle or the landing or delivery location of the vehicle.

摘要： A method and device for detecting whether a headset is on ear. Microphone signals from a plurality of microphones are used to derive a plurality of signal feature measures, which are normalized to a common reference scale. The signal feature measures are weighted based upon detected signal conditions in the microphone signals. The normalized and variably weighted signal feature measures are then combined to produce an output indication of whether a headset is on ear.

摘要： An active noise cancellation system and method, in which an active noise controller generates an anti-noise signal based on an error signal, and a loudspeaker operatively coupled to the active noise controller converts the anti-noise signal into anti-noise sound. An acoustic error sensor operatively coupled to the active noise controller picks up sound and converts the picked-up sound into the error signal. The acoustic error sensor is disposed at a front face of the loudspeaker.
