For the outer orifice correction when the axis direction ofthe orifice coincides with that of the duct, .explicit expressions were given by Ingard and Rschevkin. But their application to duct sections with duct-sidewall resonators is beyond their premise. An explicit expression ofthe outer orifice correction for duct-sidewall resonators was derived by conducting three-dimensional boundary-element analyses. Application ofthis outer orifice correction improves significantly the accuracy of the one-dimensional wave analysis for the acoustic properties of duct sections which have sidewall resonators., Article, 会議名称:The 31th International Congress and Exposition on Noise Control Engineering : additional proceedings, Sound Quality Symposium 2002, 主催学会:INCE/USA}, publisher = {Institute of Noise Control Engineering}, title = {On One-dimensional Sound Analysis of a Duct Network with Helmholtz Resonators}, year = {2002} }
