A low-noise MEMS acoustic vector sensor

2013 International Conference on Optoelectronics and Microelectronics (ICOM), 2013
A low-noise micro-machined acoustic vector sensor is presented. It is desirable that the application of difference capacitance principle combined with bulk micro-machining silicon process techniques may improve the low frequency sensitivity and dynamic range of the acoustic vector sensor as well as its miniaturization.

Influence of Acoustic Horn on Vector Sensor's Sensitivity

2013 Fifth International Conference on Measuring Technology and Mechatronics Automation, 2013
Acoustic vector sensor (AVS) attracts widespread attention for its unique advantages as a novel underwater acoustic receiver. However, compared to acoustic scale sensors, especially at low frequencies, vector sensors are typically less sensitive and possess higher electronic noise floors.

Vector sensors and acoustic calibration procedures

2019
The measurement of underwater sound for the purpose of environmental impact studies usually only involves the measurement of the sound pressure by hydrophones. Sea mammals are sensitive to sound pressure in water like land mammals are for sound pressure in air.
