抄録
Reduction of noise of a combine harvester was tried by visualization. At first, the actual state of noise was observed and understood by using a three dimensional acoustic intensity measurement system. The objective was to detect the source of noise and to map the noise generated and its transmision. Secondly, the sound intensity around the operator head was measured, and the sound flow was obtained. Based on the results, a resolution was determined and tested to install a sound isolation board within the path of sound propagation. Mainly the relationship between the shape of isolation board and sound flow was tested and discussed. Also the materials of sound isolation board were taken on account.
