What type of silencer is effective at mitigating low to mid frequency noise only?

The effective silencer for mitigating low to mid-frequency noise is one that utilizes a method of sound control specific to how sound waves interact with various physical features. The reactive silencer operates on principles that exploit acoustic impedance and phase cancellation to target low to mid-frequency noise specifically.

In designing reactive silencers, internal components are arranged and sized in such a way that they reflect sound waves coming in, but they do so in a way that causes a phase shift. When the reflected waves meet the incoming waves, they can effectively cancel each other out, reducing noise levels in the desired frequency range.

Other types of silencers, such as absorptive or resistive, have different operational focuses. Absorptive silencers primarily work on absorbing sound energy through porous materials, which might not be as effective at lower frequencies where sound waves are longer and tend to pass through these materials more easily. Resistive silencers, on the other hand, are generally designed for higher frequency applications, limiting their effectiveness in the low to mid-frequency range. Therefore, the reactive silencer stands out as the choice specifically capable of addressing low to mid-frequency noise issues effectively.
