Abstract
An acoustic sensor includes a side wall, closed at each end by an end wall, to form a substantially cylindrical cavity, a transmitter and a receiver operatively associated with first and second respective end walls. Properties of the relative dimensions of the cavity are configured to create a desired oscillatory motion of the end walls, and oscillations of a fluid pressure in the cavity, to generate an electrical signal via the receiver to be output from the sensor. An array of acoustic sensors can be connected to allow calibration of one of the array of sensors.
