The majority of devices employed in underwater communication use electromagnetic or electrodynamic processes. This paper reports on the experimental development of an underwater communicator that operates by the process of liquid modulation. The device generates acoustic energy in a flowing fluid through mechanical displacements of a modulating valve. Acoustic response of the modulator contains frequencies up to 3 kHz. Thus, it is a potential source for generating audible underwater sound. The modulator has been used with water to produce underwater speech communication that possesses excellent intelligibility. Present research has been accomplished while using low system pressure differentials. Sufficient increase of the system pressure is expected to produce satisfactory underwater communication by means of liquid modulation.
