Abstract: An audio or video conferencing system having an array comprised of two or more microphones and having one or more loudspeakers positioned proximate to the microphones. The conferencing system also has acoustic echo cancellation (AEC) functionality that removes direct and reverberant acoustic echo from microphone signals in two separate acoustic echo cancellation operations. The first AEC operation removes direct acoustic echo prior to a beamforming operation, and the second AEC operation removes reverberant acoustic echo from a microphone signal subsequent to the beamforming operation.

Abstract: Described in detail herein are methods and systems for identifying actions based on detected sounds in a facility. An array of microphones can be disposed in a facility. The microphones can detect various sounds and encode the sounds in an electrical signal and transmit the sounds to a computing system. The computing system can determine the sound signature of each sound and based on the sound signature the chronological order of the sounds and the time interval in between the sounds the computing system can determine the action being performed causing the sounds.

Abstract: A microphone comprises: a vibration member having a plate shape and formed so as to have elasticity and cause bending due to sound waves; a case having a depressed groove, which forms an air layer between the depressed groove and the vibration member since the vibration member is stacked on an upper part thereof, and coupled to the upper part of the depressed groove such that the vibration member is vibrated by sound waves; and a vibration detection unit provided on the vibration unit and the case and measuring the vibration of the vibration member vibrating by sound waves on the case, wherein when the vibration member vibrates, the air in the air layer flows so as to damp the vibration of the vibration member.

Abstract: There are provided an ultrasound image generating apparatus, which generates a high-quality ultrasound image even in a deep portion of a subject, and a control method thereof. In an ultrasound image (Img), for a portion (Ar1) equal to or less than a depth threshold value (D1), a real scanning line (L1) obtained from an acoustic wave echo signal is used. In the ultrasound image (Img), for a portion (Ar2) deeper than the depth threshold value (D1), an interpolation scanning line (L2) located between the real scanning lines (L1) is generated from an acoustic wave echo signal having a positional deviation between a focusing position of ultrasound waves and an observation target position. Also for a portion deeper than the interpolation scanning line (L2), a high-quality ultrasound image (Img) is obtained.

Abstract: Wind noise reduction in microphone signals. A first microphone signal is obtained from a first omnidirectional microphone and, contemporaneously, a second microphone signal is obtained from a second omnidirectional microphone. The first and second microphone signals are mixed to produce an output signal. Mixing involves weighting the first and second microphone signals by respective first and second signal weights to produce respective first and second weighted microphone signals, and summing the first and second weighted microphone signals together to produce the output signal. The first and second signal weights are calculated to minimise the power of the output signal.

Abstract: An audio source location, tracking and isolation system, particularly suited for use with person-mounted microphone arrays. The system increases capabilities by reducing resources required for certain functions so those resources can be utilized for result enhancing processes. A wide area scan may be utilized to identify the general vicinity of an audio source and a narrow scan to locate pinpoint positions may be initiated in the general vicinity identified by the wide area scan. Subsequent locations may be anticipated by compensating for motion of the sensor array and anticipated changes in source location by trajectory. Identification may use two or more sets of characterizations and rules. The characterizations may use computationally less intense analyses to characterize audio and only perform computationally higher intensity analysis if needed. Rule sets may be used to eliminate the need to track audio sources that emit audio to be eliminated from an audio output.

Abstract: A speaker module, An electronic device, and a display device include a housing, a main board, and at least one speaker module placed in the housing. The at least one speaker module includes at least one first speaker unit disposed in a first direction and at least one second speaker unit disposed in a second direction different from the first direction and having at least one side of the at least one second speaker unit contacting with at least one side of the at least one first speaker unit. Driving vibrations may be offsetted because the speaker units are disposed in different directions.
