摘要:
In the course of a study of the basic properties of acoustic linings for ducts transmitting air at high speeds, experimental evidence indicated that aerodynamic noise generated by the flowing air could limit the magnitude of noise attenuation inside the duct achievable by means of linings. A discussion of the matter leads to the conclusion that aerodynamic noise generated by the fluid flow could limit the maximum attenuation achievable.
