The spectrums of noise discharged out of excavator diesel, noise exhausted through resistance muffler, noise well radiation of the diesel and the noise in manipulator cell has been analyzed with the corresponding noise signal collected, and the A sound pressure levels have been measured with different diesel rotation respectively. Conclusions have been obtained as following: the noise signal discharged out of excavator diesel covers high, middle and low band widely; all the kinds noise signal have similar spectrum with different amplitude; the vibration is much bigger at idle speed is than the others; the noise strength increases with the diesel rotation rising. Low band frequencies with big spectrum amplitude of noise resource and the other noise signal collected are multiples of diesel rotation.
