Abstract
For examining sound field in automobile cabin, it is important to visualize a noise source and it's behavior. This paper reports the results of visualized sound field using measurement data of sound intensity analysis. In general, it is difficult to obtain an appropriate result for source localization in reflective sound field where normal mode can be occurred with sound intensity analysis. We tried to distribute many receiving points and examined noise source localization in automobile cabin with this technique and found it effective. After the treatment of sound insulation, we found that measurement results reveals difference with and without countermeasure.
