Airport noise is noise pollution produced by any aircraft or its components, during various phases of a flight, especially the landing phases. This paper study the airport noise prediction model basing on WECPNL(Weighted Equivalent Continuous Perceive Noise Level) recommended by ICAO as a index. With the measurement data, which is properly distribute to the final of active runway and centerline, a brief summary of WECPNL-based prediction model from touchdown to runway centerline is established. However, the results showed a discrepancy of certain points was between prediction and measurement data, especially 1.5-2.5 km away from the airport. Therefore, an amendment was proposed with greater accuracy, which the relative of the new model for future prediction ranged from 1.0% to 2.0%. To some extent, this model also can reflect and make full use of the limited data with a high accuracy, especially suit for monitoring rapidly in some new small airports.
