説明
We have examined how to compose multiple-section resonators to attenuate air-conditioning duct noise. Regarding characteristics of resonance frequency the maximum transmission loss was produced when the resonators had a space of one-fourth of the resonance wavelength. Regarding double-section resonators the equal value of the absorption loss to the transmission loss was obtained by making normalized acoustic resistance of the up-stream resonator "R+1" against "R" of the down-stream resonator. And we stated possibility of applying to air-conditioning ducts by comparing the frequency characteristics of multiple-section resonators.
