Introduction

The noise measurement simulation service provides the noise measurement of the construction work and traffic in a variety of site (arbitrary measurement) and the result with the option which can be selected in addition to "Supercomputer noise analysis simulatioin service" (please see Up&Comoing Vol.93). This service is very useful for checking, comparing, and studying the measurement result by using the actual measurement result as well as the visualized noise analysis simulation result.  The figure 1 shows the flow of the noise measurement simulation service.

Detailed information of the service

Noise measurement simulation service The noise measurement can be classified as follow. This service supports "arbitrary measurement". Arbitrary measurement: Custom-made measurement without the specific standard Road noise measurement : "Evaluation manual of environmental criteria on noise II. -Area evaluation (Area facing the road )" April 2000, Compliant with Environment agency Measurement of construction works noise : "Guideline of noise measurement in construction work (Plan)" 2007, Copliant with Civil Engineering Research Institute General type of noise The manual of evaluation and measurement is prepared for the following noise type, and () showes the name of each forecasting model. Noise of general environment Noise of traffic road(ASJ RTN-Model2008) Noise of conventional rail Noise of Shinkansen (bullet train) Noise of airplane Noise of construction work(ASJ CN-Model2007) With this service, the noise of traffic road and the construction work are focused. Measurement equipment Noise level meter(Sound level meter) : JIS C 1509-1 Calibrator : JIS C 1515 Level recorder : JIS C 1512(scheduled) Data recorder : No JIS  standard, 20Hz-10kHz is supported(scheduled) Frequency analyzer : JIS C 1513(scheduled) Noise level meter NL-42 Sound pressure level when the noise is  measured at a location for 10minutes
