Abstract

At factory or plant, sometimes the low frequency noise, which has components less than100Hz, becomes a serious problem together with the noise in ordinary frequency. It is known that the countermeasure of low frequency noise is more difficult than the noise in ordinary frequency. In this article, basic knowledge of the low frequency noise problem is summarized. Also the noise countermeasure techniques which are applicable for the low frequency noise problem are introduced.
