ABSTRACT: A combined numerical-experimental procedure for abating noise in rotary offset presses has been developed and testing. In the first stage, sound pressure and acceleration measurements were made on a test machine assembled in the laboratory. Two techniques, plate damping and structural modifications based on modal analysis, were combined to achieve reduction in the amplitude of the plate vibrations, found to be the major source of sound pressure.
