Acoustic vector sensors provide a measurement of both the scalar acoustic pressure as well as the acoustic particle velocity vector in the orthogonal Cartesian directions. allowing for direction of arrival estimation of an acoustic source. Typically. acoustic vector sensors are used in array configurations in place of hydrophones to increase the overall array gain and directivity. https://www.roneverhart.com/Madrid-The-Leadfoot-Zak-Maytum-Pro-Model-32-Freeride-Deck-Performance-Series/
