Evaluation of an Inclined Mounting System for Diesel Engines

Abstract

The diesel engine in a 40-foot test craft was installed on an inclined mounting system in effort aimed at reducing sound levels aboard craft. An evaluation of the vibration levels and sound levels in the boat cabins indicated that the mounting system was very effective to the degree that airborne sound transmission and propeller reduced noise now control the acoustical environment. Keywords: Diesel engines, Acoustical enclosures, Vibration isolation, Noise reduction.
