Microphone Based Acoustic Vector Sensor for Direction Finding with Bias Removal [PDF]
Archives of Acoustics, 2022 The acoustic vector sensor (AVS) is used to measure the acoustic intensity, which gives the direction-ofarrival (DOA) of an acoustic source. However, while estimating the DOA from the measured acoustic intensity the finite microphone separation (d) in a ...

Acoustic Vector-Corrected Impedance Meter [PDF]
, 2014 We describe the development of a novel instrument intended for the measurement of the acoustical reflection coefficient of materials. The instrument effectively implements a one-port vector-corrected network analyzer in the acoustic, rather than the ...

Vector Sensor Beam Steering for Underwater Acoustic Communications [PDF]
Proceedings of Meetings on Acoustics, 2020 Acoustic Vector Sensors(VS) have been widely used for direction-of-arrival estimation in the past, while the employment of VS for underwater communications is a recent topic. Due to its compact size, VS may be used as a receiver in applications such as on board of Unmanned Underwater Vehicles (UUV), providing higher maneuverability and operational ...

Acoustic tamper detection sensor with very low false alarm rate [PDF]
, 2008 We describe a device designed to detect interference (vandalism or tampering) by acoustic means. The design employs both a piezoelectric vibration transducer and a common microphone in a novel mechanical arrangement.
