Environmental protection departments call develop reasonable measures to protect the environment according to timely and accurate measurement analysis.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, and provides the theory basis for noise control airport.The use of the MFC VC + +6.0 is used to develop simple calculate and sophisticated calculate are divided into two modes, you can calculate the effective perceived noise level LEPN and weighted equivalent continuous noise level feeling LWECPN.
