PROBLEM TO BE SOLVED: To provide a method of evaluating noise in a telescopic device for a road bridge that has an advantage in accurate evaluation of the noise generated at a portion of the telescopic device even under an environment that a traffic volume is small.;SOLUTION: In sampling data obtained by sampling a noise level of noise generated at a portion of a telescopic device for a road bridge for a predetermined sampling cycle, sampling data not lower than a background noise threshold are extracted as first extraction data. In the first extraction data, sampling data satisfying a condition predetermined on the basis of the first extraction data is extracted as peak data. Data for evaluating noise is generated on the basis of the extracted peak data so as to be output.;COPYRIGHT: (C)2010,JPO&INPIT
