It is important to increase the sound proof performance of building for reduction the influence of aircraft noise on the basic of actual survey of existed buildings. The purpose of this study is to propose the sound proof method about indoor noise of a movie theater due to aircraft. In this study, field measurement of aircraft noise level difference were carried out for 5 type aircraft. As the result, aircraft noise levels showed to be 83.6∼98.3dB(A) and indoor noise level were NC-50∼NC-65 over acceptable NC-30 in a movie theater. Noise reduction effect showed to be NC-15∼NC-30 in a movie theater.
