WebJan 19, 2014 · A Helm resonator is a box or tube with an opening or slot at its mouth. Air enters the slot which has a calculated width, length, and depth. The slot is attached to a cabinet or cylinder of different widths and depths. A glass coke bottle is a good example of a Helmholtz resonator. WebThe resonator works by absorbing the sound waves that are produced by the engine, which results in a quieter engine operation. In addition to reducing noise, the resonator also helps to improve engine performance by reducing air resistance. Conclusion: The purpose of the engine air intake resonator is the only component that helps to reduce noise. WebNov 6, 2014 · Then you take the frequency that you want to cancell out, and build a helmholtz resonator to the correct length. v = f (Lamda) so find the speed of sound for hot exhaust air. use 391m/s in you v = f (lamda eq) to find Lamda Then 1/4lamda is the length of the branch resonator (Helmholz resonator). slurring words when drunk
