of the tube 28 to form a first helmholtz resonator chamber the first helmholtz resonator chamber communicates with the hollow portion of the tube 28 through one of the apertures 36 thereby forming a helmholtz resonator three other helmholtz resonators are similarly formed and cooperate to form a helmholtz resonator section 70 fewer or more helmholtz resonator sections may be used without departing from the scope and spirit of the invention an annular entry type resonator 72 is formed in the cover section 16 for attenuating low frequency noise the tube 50 extends from the tube 28 and a desired distance into the tube 56 a clearance exists between the outer wall of the tube 50 and the inner wall of the tube 56 the annular entry into the chamber of the annular resonator 72 is formed by the clearance between the outer wall of the tube 50 and the inner wall of the tube 56 the noise enters the chamber of the annular resonator 72 through the clearance it is understood that other resonator types could be used such as an expansion chamber type for example in place of the above resonator types without departing from the scope and spirit of the invention in operation air enters the resonator system 10 through the air inlet 20 as indicated by the arrow 64 the air travels through the conduit formed by the air inlet 20 the tube 28 the tube 50 and the outlet section 18 through the air cleaner 62 and into an associated engine 74 noise generated by the engine 74 travels.
