초록
Exact and precise noise measurement is the basis for the reduction measure R&D, impactassessment and prediction modeling for railway noise. In this study, research trend as well asnational and international noise measurement standard are investigated. For the estimation ofvertical radiation characteristics of railway noise, specially devised zig was used. From the noisemeasurement and analysis, exact noise height radiated from the railway was characterized. Theobtained results will be used for the suggestion of the height of microphone position of railwaynoise measurements.
