A resonator as disclosed that has a plurality of resonating chambers having a predetermined size that attenuate sound in a conduit. The resonator may be disposed along the inner periphery of the conduit. Alternatively, it may be disposed on the outside periphery of the conduit so that flow through the conduit may be unrestricted. Additionally, the resonator may include a honeycomb fairing to attenuate sound at higher frequencies. Also disclosed is a system in which a resonator may be located within the conduit of an HVAC system to attenuate the sound.

[ What is claimed is:] [1.] A system for the ventilation of a space comprising:a ventilation conduit having a longitudinal axis;a ventilation fluid control device disposed in said conduit; anda resonator disposed in fluid communication with said fluid control device, said resonator including a resonating chamber having a predetermined longitudinal length substantially parallel to the longitudinal axis that corresponds to a function of a wavelength of sound at a first frequency, above 200 Hertz, generated by said fluid control device, that is primarily attenuated by said resonating chamber, and a height, wherein the first frequency will remain the frequency of primary attenuation regardless of said height of said at least one resonating chamber.
