Sound Suppression Kits

SOUNDPROOFING FOR AIRCRAFT CABINS

Originally installed OEM sound suppression material degrades over time. Replacing it is not an easy task. At ZenithJet, we developed the Silentium Air Sound Suppression System based on years of studying aircraft interiors during test flights and major inspections, seeing first-hand where deficiencies in materials and their installation exist. Our FAA Supplemental Type Certificate (STC) approved sound suppression kits not only restore factory sound levels but are engineered to pass stringent regulatory standards.

Adding sound suppression kits that are not STC approved not only pose a significant risk to your aircraft’s residual value, they can jeopardize a future sale of your aircraft as well. Non STC alterations to your aircraft are not universally accepted by international regulatory authorities. With the increased volume of global transactions involving different registries, why would take that risk?


SOUND SURVEYS

If you are considering a sound suppression upgrade for your aircraft and you want to gather “before” and “after” sound survey results, or you would like to independently validate work already completed, Zenith Jet can help. Using industry leading Brüel & Kjær sound measurement equipment, our sound survey team will assess the current sound levels of your aircraft’s cabin and submit a detailed report that measures each station separately.
