Impedance silencer

Product Description
Impedance silencers belong to the category of impedance‑composite silencers, combining the advantages of both resistive and reactive silencing designs. The resistive section attenuates mid‑ and high‑frequency noise by means of porous sound‑absorbing materials, while the reactive section employs expansion chambers and resonant cavities to exploit sound‑wave reflection and interference, thereby reducing low‑frequency and pulsating noise.
This product addresses the limitations of single‑type reactive silencers—namely, weak low‑frequency noise reduction—and single‑type resistive silencers—namely, poor high‑frequency performance—thereby achieving broadband noise attenuation. The SE series impedance silencer embodies this design; its external dimensions can be customized to suit site conditions, and its sound attenuation increases with effective length (while resistance rises in tandem), making it well suited for a wide range of broadband noise sources, including blowers, centrifugal fans, air compressors, and more.
