• In this paper the author gives a review about the measurement and analysis method of railway noise in Japan.First, the environmental goals for Japanese railways are introduced.Both Shinkansen and non-Shinkansen line standards have their own basis, and averages of Lmax and Leq are used respectively.Next, measurement of railway noise to evaluate the fulfillment of environmental standards is introduced.The status quo and future necessity of automatic data processing is described.Third, the author describes technical aspects of noise measurement and evaluation, that is, to locate noise sources and to estimate their contribution in the wayside.Since the observation time is very short, the variety of equipment is limited.It is thus an important technique to compare observed data to estimate the contribution of noise sources.Finally, the author briefly states about the basic ideas of formulating the equations of wayside noise assessement.
