| Abstract: | By means of measurement and analysis of noise near certain asphalt paver driver's ear andnear-field noise of main noise sources, the noise source which contributions to noise near driver's ear was identified.According to the characteristics of the noise source, some measurements to reduce noise are taken. As a result, paver noise is decreased obviously. And on the basis of these measurement, some design change proposals are put forward to improve paver for reducing the noise. |
