Absorptive Silencers

Absorptive silencers use sound-absorptive media to provide effective attenuation on high-noise frequencies (500-8,000 Hz). At frequencies above or below this range, attenuation performance is somewhat diminished.

Construction Absorptive Silencers

Since noise is absorbed by the media, absorptive silencers do not rely on internal baffles, tubes or other restrictive devices to achieve noise reduction. Consequently, absorptive silencers generally employ a “straight-through” or similar internal designs that cause minimal air-flow restriction.
