Abstract

The acoustic field consists of oscillating particles causing pressure fluctuations. Many aquatic organisms can detect the particle acceleration in the acoustic field and are therefore sometimes more susceptible to this component of the sound field rather than to the acoustic pressure (Kalmijn 1988). In this study, the particle acceleration generated by various boat types is measured using two hydrophones.
