Web15 nov. 2011 · λ = v/f = speed of sound / frequency. λ = (343m/s)/ (133.34Hz) λ = 2.572 meters. This gives you the length of a full sound wave. The idea here is to reintroduce a sound wave into the exhaust that is 180° out of phase with your drone frequency. To do this, you build your resonator tube at exactly one-fourth the length of the resonant wave. Web22 sep. 2024 · To attenuate the noises at identified frequencies Helmholtz resonator was introduced, which is particularly effective for low frequency noise attenuation. A design is …

The IPD-kit comes with a silicon hose to fit the bigger TB. This hose by-passes the Helmholtz resonator. There is a flexible silicone cap to close the open hole of resonator box.... Web14 okt. 2014 · The solution is a 1/4 wave resonator tube. Simply put, it is a small piece of exhaust pipe with a flat capped end welded nearly perpendicular to the exhaust flow post-muffler that serves to take some of the resonant amplitude and shoot it back into the exhaust pipe out of phase with the resonant frequency to bring down the amplitude. technolam blufango
