Attenuation of sound in lined circular ducts
(Cambridge : Gas Turbine Laboratory, Massachusetts Institute of Technology, [1975], 1975)In the previous report, we have used approximate expressions for the wall impedance for the discussion of sound attenuation in lined circular ducts. For instance, Eq. (2.5) has been used for the wall impedance of a circular ... -
Attenuation of sound in lined ducts
(Cambridge, Mass. : Gas Turbine Laboratory , Massachusetts Institute of Technology, [1974], 1974)Extensive computations have been carried out of the attenuation characteristics of resonator and porous type duct liners in rectangular and circular ducts. First the frequency dependence of the attenuation constant and the ...
