摘要： 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.
