| Abstract: | Based on the theory of the viscous damping of sound wave in tube, the acoustic transmission property of the perforated plate in vactive muffler is analyzed in the presence of airflow. The experimental results show that acoustic resistance of perforated plate is related to plate thickness, aperture diameter, numbers of aperture, acoustic frequency and airflow velocity. |
