The acoustic vector sensor: a versatile battlefield acoustics sensor
SPIE Proceedings, 2011The invention of the Microflown sensor has made it possible to measure acoustic particle velocity directly. An acoustic vector sensor (AVS) measures the particle velocity in three directions (the source direction) and the pressure. The sensor is a uniquely versatile battlefield sensor because its size is a few millimeters and it is sensitive to sound

The Acoustic Vector-Sensor's Near-Field Array-Manifold
IEEE Transactions on Signal Processing, 2010The acoustic vector-sensor is a practical and versatile sound-measurement system, for applications in-room, open-air, or underwater. Its far-field measurement model has been introduced into signal processing over a decade ago; and many direction-finding algorithms have since been developed for acoustic vector-sensors, but only for far-field sources ...

Beamformer performance with acoustic vector sensors in air
The Journal of the Acoustical Society of America, 2006For some time, compact acoustic vector sensors (AVSs) capable of sensing particle velocity in three orthogonal directions have been used in underwater acoustic sensing applications. Potential advantages of using AVSs in air include substantial noise reduction with a very small aperture and few channels.

Acoustic pressure-vector sensor array
The Journal of the Acoustical Society of America, 2004Pressure-vector sensors measure both scalar and vector components of the acoustic field. December 2003 measurements at the NUWC Seneca Lake test facility verify previous observations that acoustic ambient noise spectrum levels measured by acoustic intensity sensors are reduced relative to either acoustic pressure or acoustic vector sensor spectrum ...

Mesh-type acoustic vector sensor
Journal of Applied Physics, 2017Motivated by the predictions of a theoretical model developed to describe the acoustic flow force exerted on closely spaced nano-fibers in a viscous medium, we have demonstrated a novel concept for a particle velocity-based directional acoustic sensor.

A fibre laser acoustic vector sensor
SPIE Proceedings, 2009An acoustic vector sensor based on distributed feedback fibre laser technology is reported. The sensor is designed as an accelerometer that will sense acceleration induced by the difference in acoustic pressure across the sensor. Experimental measurements demonstrate that the sensor has excellent response characteristics and sufficient cross-axis ...

Design and experimentation with acoustic vector sensors
2009 International Symposium on Ocean Electronics (SYMPOL 2009), 2009Directional underwater sensors have two appealing capabilities; the ability to selectively reject noise emitted from discrete interfering noise sources and the ability to localize, track, and range targets using suitable signal processing algorithms.

Acoustic vector sensors and vector/tensor processing in ocean acoustics research
The Journal of the Acoustical Society of America, 2008Several passive sensor systems that simultaneously measure acoustic pressure and the three components of acoustic particle motion have been designed and deployed in seagoing experiments by the Marine Physical Lab over the past two decades. Descriptions of these sensor systems and results from applying various signal/array processing methods with these ...

Localization of sound sources with dual acoustic vector sensor
2019 Signal Processing: Algorithms, Architectures, Arrangements, and Applications (SPA), 2019The aim of the work is to estimate the position of sound sources. The proposed method uses a setup of two acoustic vector sensors (AVS). The intersection of azimuth rays from each AVS should indicate the position of a source. In practice, the result of position estimation using this method is an area rather than a point.
