An electronic device is provided. The electronic device comprises a speaker, a plurality of microphones, at least one processor operatively connected with the speaker and the plurality of microphones, and a memory operatively connected with the at least one processor, wherein the memory is configured to store instructions which, when executed, cause the at least one processor to perform speech audio processing or non-speech audio processing on audio signals received via the plurality of microphones, upon obtaining a non-speech audio signal based on the speech audio processing or the non-speech audio processing, identify a non-speech audio signal pattern corresponding to the non-speech audio signal, obtain a non-speech audio signal-based first command based on the identified non-speech audio signal pattern, and perform at least one action corresponding to the obtained non-speech audio signal-based first command.

Disclosed are methods and systems which convert a multi-microphone input signal to a multichannel output signal making use of a time- and frequency-varying matrix. For each time and frequency tile, the matrix is derived as a function of a dominant direction of arrival and a steering strength parameter. Likewise, the dominant direction and steering strength parameter are derived from characteristics of the multi-microphone signals, where those characteristics include values representative of the inter-channel amplitude and group-delay differences.

Disclosed are methods to manipulate a given parametrized haptic curve in order to yield a smooth phase function for each acoustic transducer which minimizes unwanted parametric audio. Further, the impulse response of a haptic system describes the behavior of the system over time and can be convolved with a given input to simulate a response to that input. To produce a specific response, a deconvolution with the impulse response is necessary to generate an input.

Disclosed herein is a mixed reality application to use a multi-channel audio input to identify a character and origin of a given sound, then present a visual representation of the given sound on a near eye display. The visual representation including a vector to the source of the sound. The visual representation further including graphical elements that describe various attributes of the given sound including the magnitude, directionality, source, and threat level. Where the source of the given sound is moving, the visual representation shifts to illustrate the movement.

Systems and methods are provided for monitoring the structural integrity of a vehicle. In particular, systems and methods are provided for using transducers positioned at various location in and on a vehicle to measure parameters related vehicle structural health. In various implementations, the integrity of the vehicle frame and the integrity of the vehicle body are monitored using a multi-axis accelerometer and/or microphone. The use of transducers for monitoring can replace time-consuming and expensive manual inspections.

A system includes a microphone unit coupled to a roof of an autonomous vehicle. The microphone unit includes a microphone board having a first opening. The microphone unit also includes a first microphone positioned over the first opening and coupled to the microphone board. The microphone unit further includes an accelerometer. The system also includes a processor coupled to the microphone unit.

Disclosed is a laser irradiation state diagnosing method which allows accurately diagnosing a laser irradiation state. When irradiating a laser beam so that an irradiation spot scans the surface of the irradiation object, acoustic information in vicinity of the irradiation spot is acquired. And based on characteristics of the acoustic information, such as an intensity of a component of a specific frequency band or a frequency band distribution, a state of peeling of the adhered substances existing on the surface of the irradiation object is determined.

A right seat processing unit includes, assuming that a voice of a user in a right front seat is a right front seat voice, a filter HR that converts the right front seat voice being output from a left front seat microphone disposed on a headrest of a left front seat into the right front seat voice collected by a right seat virtual microphone that is a virtual microphone located on a left side of a headrest of the right front seat, a delay unit Z.sup.-TR that delays and outputs an output from a right front seat microphone located on a right side of the headrest of the right front seat, a filter VVRA that extracts the right front seat voice being output from the filter HR, a filter WRB that extracts the right front seat voice being output from the delay unit Z.sup.-TR, and a right adder that adds outputs of the filter WRA and the filter WRB and outputs an added output as a right front seat speech voice signal.

Examples described herein relate to transitioning a playback session between portable playback devices such as “smart” headphones, earbuds, and handheld speakers with playback devices of a zone-based media playback system. Exemplary techniques facilitate continuity of playback when transitioning between locations (e.g., from at home to on-the-go or vice versa) or between listening paradigms (e.g., personal or out-loud playback of audio content). An example implementation includes detecting a swap trigger, determining the source playback device(s) and target playback device(s), and performing a playback session swap between the source playback device(s) and target playback device(s).
