Abstract:

Nearfield and farfield measurements were performed on scale model-linear- and hexagonal underwater sound arrays of acoustically small elements ka approximately 1. The measurements included the head velocities of the elements, surface pressure and far-field pressure. The linear superposition of the acoustical interaction effects was studied and proved to be valid. A simple method to predict the final velocities of the interacting elements was established by using the modified-transfer-coefficient concept. Author
