Abstract
There are some types of sound localization methods which are used for noise source identification of prototype products in machine development. In this paper, the experiments of noise localization are done to analyze the linear noise slider mechanism which make a transient noise. As a noise source localization method, the Near field Acoustic Holography(NAH) was used. Some experiments showed that the motor vibration of linear slider cause resonance in the inside of linear slider. After that, we tried to reduce the noise level.
