Abstract: A circulating water system is contained in a portable box. The water system includes a tray which carries the water from an overflow chamber and breaks up the water flow before dropping it onto a reservoir surface. Water dropping onto the reservoir surface creates sounds which are carried primarily through openings provided in the box. The sounds are transmitted to the immediate surroundings and are analogous to sounds emanating from naturally occurring water streams. Various trays are described which provide different sound intensities and tones.
