Along with our country aviation business of continuously development,airport noise problem increasingly salient. Therefore measurement of aircraft noise around airport becomes very important.
This thesis mainly study measurement of aircraft noise around airport, namely precise method and simple method. Precise method’measure outcome is more exactness, simple method use A-weight network to calculate, windage is rather big when use sound level plus 13dB close to calculate perceived noise level. Precise method have 24 frequency dot’ data participate in calculate, and that simple method is simple through equivalent sound level to calculate, calculate is simple. Compare this two measure method’s measure outcome can know that simple method and precise method’s measure outcome exist difference. This two LWECPN’ average difference is -0.53dB, then use -0.53dB to have a correct to simple method’ measure outcome. Corrected measure outcome of simple method is more close to precise method’ measure outcome , and their average difference is almost to be zero.
