Study in radiation characteristics of intermittence exhaust noise

    Graphical Abstract
    • Abstract
  • Exhaust noise is divided into three classes.Aerodynamics characteristics and the noise characteristics inthe course of illtermittence exhaust are investigated.The expressions for sound pressure level of the noise generated byannuploe source and quadrupole source induced by the intermittence exhaust noise are established.Effects of each of allparameters in pneumatic system on the noise value are comprehensively and thoroughly studied.
