A suspension system was constructed in conformity with earlier results for the effects of a model cab suspension on vibration and noise reduction. The relationship of suspension system, air-borne sound and resonance were also investigated. Cab vibrations were suppressed. Sound pressure level in the cab was reduced, but showed a slightly higher value than that for a fixed cab at some engine speeds. Noise reduction was slight because of high frequency sound components.
