A Case Study for the reduction of Mini Excavator Radiated Noise

This paper is a case study for the reduction of excavator Radiated noise. The main purpose of the study is to reduction noise for the cooling fan and hydraulic line which is main noise source of the excavator. Recent, noise regulations for the construction equipment is becoming stricter. Compare to past excavator drivers requirements for noise level demanding are becoming more and more.
