摘要：
A systematic study of the methods of measuring wall pressure fluctuations against a background of intense vibrations is carried out. The method of separating the turbulent signal from noise on the basis of monitoring the level of vibration interference is considered. Active methods of vibration control are developed for a miniature receiver of turbulent pressure fluctuations. It is shown that the methods based on the spatial filtering C, of the noise field offer the greatest promise. The filtering properties of vibration-proof receivers and measuring systems are investigated. (C) 2003 MAIK "NaukalInterperiodica".
