SIMULATOR FOR RESIDENCE NOISE ENVIRONMENT USING INTERNET

摘要

PURPOSE: A simulator for a residence noise environment using the Internet is provided to supply a forecast service with respect to a noise environment. CONSTITUTION: The three-dimensional earth surface information, three-dimensional building information, and a surface reflection characteristic thereof are inputted to the server computer. A kind and a position of a noise are inputted to the server computer. A position of the person is inputted to the server computer. Eight frequency bands are divided based on the three-dimensional earth surface information, the three-dimensional building information, the surface reflection characteristic thereof, the kind and position of the noise, and the position of the person. A sound file is manufactured based on each noise simulation result with respect to the eight bands calculated in the server computer.
