A. Selamet et V. Easwaran, MODIFIED HERSCHEL-QUINCKE TUBE - ATTENUATION AND RESONANCE FOR N-DUCTCONFIGURATION, The Journal of the Acoustical Society of America, 102(1), 1997, pp. 164-169
The classical two-duct Herschel-Quincke tube is generalized to an n-du
ct configuration. A closed-form expression is developed for the transm
ission loss characteristics, as well as for the resonance locations. W
hile the results are illustrated in the present study in terms of thre
e-duct configurations alone and in comparison with the two-duet arrang
ements, the developed expressions hold for any number of ducts and cro
ss-sectional area combination. (C) 1997 Acoustical Society of America.
