THE ABATEMENT OF STRUCTURAL NOISE IN INTERNAL COMBUSTION ENGINES

THE MECHANISM OF STRUCTURAL NOISE IN INTERNAL COMBUSTION ENGINES IS DEFINED, AND ITS ABATEMENT IS CONSIDERED. STRUCTURAL NOISE IS SHOWN TO DOMINATE THE OTHER SOURCES OF ENGINE NOISE AT HIGH FREQUENCIES. THE ABATEMENT OF ENGINE STRUCTURAL NOISE BY EMPLOYING THE FUNDAMENTALS OF ISOLATING HIGH-FREQUENCY VIBRATIONS, REDUCING THE RADIATION EFFICIENCY OF FINITE PANELS, AND DAMPING RESONANT VIBRATIONS IS DISCUSSED.
