Abstract

This paper describes the test results of a procedure to measure the directional response of a vector intensity hydrophone array. The NORDCO 3-D hydrophone array was designed to simultaneously capture the three components of a sound intensity vector. The phase matched array requires accurate positioning of the receiver elements to achieve a real time response. To calculate the directional response of the array, the x, y and z components of a sound intensity field point produced by a stationary source were measured while rotating the array about its z axis. The resulting sound intensity curves showed the expected cosine patterns with the minima of the x and y components spaced precisely 90° apart.
