To timely and accurate environmental noise measurement analysis to the environmental protection department formulate measures of environmental protection, it is to measure the level of protection area indexes. This paper airplane noise around the airport to measure analysis software, can be collected aircraft noise is analyzed, the noise of the detailed list, helps people to study the essence of the noise, provides the theory basis for noise control airport. The use of vc + + 6.0, divided the MFC to develop simple algorithm and precision algorithm two modes, can be calculated LEPN noise effectively plan and feel right LWECPN equivalent continuous noise levels feeling.
Environmental noise measurement and analysis of timely and accurate environmental protection departments will help develop a reasonable environmental protection measures, is a measure of the level of regional environmental protection one of the important indicators. This article describes measurements of aircraft noise around airports analysis software, can be collected to analyze aircraft noise, the noise out more information, help people to study the nature of aircraft noise, airport noise to provide for the control theory. The use of the MFC VC + +6.0 is used to develop simple algorithms and sophisticated algorithms are divided into two modes, you can calculate the effective perceived noise level LEPN and weighted equivalent continuous noise level feeling LWECPN.
