The sound abatement cabinet permits extended processing without discomfort by greatly reducing high pitched noise that is produced in ultrasonic processing by harmonics emanating from the vessel walls and the fluid surface. The inside of the cabinet is lined with sound abating foam. One hole at top for lead from power supply, two holes at bottom for water inlet/outlet, etc. All holes are covered with slit rubber. 1/2" vertical mounting rod located towards rear to left is for mounting ultrasonic reactor.
