Control of Hydraulic System Noise in a Military Vehicle 780758

Retrofit noise controls were developed to reduce the noise exposure of the operator of a large Army forklift truck. Various noise sources were studied and modified. The overall success of the program determined by the reduction achievable in hydraulic system noise reaching the operator by airborne, fluid-borne and structure-borne paths.
Practical retrofit modifications to reduce hydraulic system noise included component replacement, introduction of flexible fluid lines, vibration isolation and vibration damping. The overall noise at the operator's ear was reduced by 15 dB(A) without the use of a cab and by 22 dB(A) with a cab.
