Study on phase detection of traffic noises

Study period:2000 - 2002
Research overview:
Phase detection has been required for grasping situations of traffic noises by a revision of the environmental standard. A system for phase detection of regional noises is established using stochastic formula since correspondence by actual measurements and surveys seems to be difficult.
