Reactive silencer
WebPassive Reactive Silencer — Internal cavities produce acoustic wave reflections that reduce noise propagating downstream. Reliable Performance — No internal acoustic packing … WebSep 1, 2007 · Reactive silencers operate on the basis of mismatching acoustic impedance. Whenever a sound wave meets a change in the acoustic impedance, some of its energy is reflected back to the source or back and forth within the silencer. An example of a reactive muffler is shown in Figure 1. FIGURE 1 Diagram of reactive mufflers showing expansion …
