摘要： An indoor sound-modulating device is provided. The indoor sound-modulating device includes a low-frequency noise detector, an automatic actuator and an audio signal generator. The low-frequency noise detector detects low-frequency noise and generates a first modulating signal in response to the detected low-frequency noise. The automatic actuator issues a second modulating signal in response to a predetermined state. The audio signal generator generates a low-frequency audio signal for eliminating the low-frequency noise in response to the first modulating signal and generates a high-frequency repellent audio signal in response to the second modulating signal. The low-frequency audio signal has a frequency ranging from 20 Hz to 350 Hz, while the high-frequency repellent audio signal has a frequency not less than 8000 Hz.

摘要： A method and system for attenuating noise comprises identifying a location in an area at which sound emitted from one or more speakers has acoustic characteristics that are substantially similar in measure to corresponding acoustic characteristics of the emitted sound at a location approximated to be near an ear of an occupant of the area. A microphone, which may be a virtual microphone, is disposed at the identified location. The microphone detects sound at the identified location. In response to the sound detected by the microphone, the one or more speakers emit a noise-canceling audio signal adapted to attenuate one or more frequencies in the sound detected by the microphone.

摘要： A microphone includes a housing unit, a capsule unit mounted on the housing unit, a noise-counteracting unit electrically connected to the capsule unit with opposite electrical polarity, and a damping unit connected to the housing unit. The capsule unit generates a primary electrical signal composed of a primary signal part attributed to an acoustic wave and a secondary signal part attributed to a first mechanical wave which is generated due to vibration of the housing. The noise-counteracting unit generates a secondary electrical signal attributed to the first mechanical wave and having an electrical polarity opposite to that of the primary electrical signal, so that the secondary electrical signal may counteract the secondary signal part of primary electrical signal. The damping unit generates a second mechanical wave to counteract the first mechanical wave when the first and second mechanical waves are transmitted to the capsule unit.

摘要： Some implementations involve receiving location information for each of a plurality of audio devices in an audio environment, generating, based at least in part on the location information, rendering information for a plurality of audio devices in an audio environment and determining, based at least on part on the rendering information, a plurality of echo reference metrics. Each echo reference metric may correspond to audio data reproduced by one or more audio devices of the plurality of audio devices. The rendering information may include a matrix of loudspeaker activations. Some examples involve making, based at least in part on the echo reference metrics, an importance estimation for each of a plurality of echo references, selecting, based at least in part on the importance estimation, one or more echo references and providing them to at least one echo management system for canceling or suppressing echoes.

摘要： A method for generating anti-noise comprises receiving a sound signal representative of ambient sound including noise from a noise source, anti-noise from an anti-noise generator, and propagation noise from environment; processing the sound signal using a deep learning algorithm configured to generate an anti-noise signal to form anti-noise; and outputting the anti-noise signal to the anti-noise generator. The deep learning algorithm features an iterative encoder module forming plural feature maps; an attention module generating plural attention maps respectively based on the feature maps; a recurrent neural network (RNN), with long short-term memory layers receiving the feature map of the final iteration of the encoder module, predicting a future portion of the sound signal and modelling temporal features of the feature map of the final encoder module iteration; and an iterative decoder module mapping the output of the RNN to the anti-noise signal having common dimensions as the sound signal.
