An improvement of the simple estimation method of low-frequency aircraft noise under the contamination of wind noise

摘要

This paper describes an improvement of the simple estimation method of low-frequency aircraft noise contaminated by wind noise. The method is based on the use of two kinds of information on the wind noise: (1) the wind speed and (2) the infrasonic components of the wind noise. The effectiveness of the proposed method is shown through simulation experiments by using actually observed aircraft noises and the wind noise.
