In these days, knowing the contributions of noise transfer path are very important to reduce noise level. The Noise Path Analysis is widely used to estimate path contributions. The operation force identification method is merged with Noise Path Analysis to predict the response noise level. There are several methods for Noise Path Analysis, the matrix inversion method is commonly used. In this paper, the matrix inversion method based on acoustic pressure is represented to replace those method based on source strength for air-borne noise. It is simulated with two acoustic sources in semi-anechoic chamber for proving its availability. The result of simulation shows good agreement with method based on source strength.
