Aircraft jet engine manufacturing & maintenance require to install the engine in a room and test it in full power. 

Silentec design-build and guarantee that up to 150 dBA noise, in the engine room, is reduced to 60's & 70's dBA in the adjacent rooms and down to 40 dBA at the outdoor property line.

For this,  Silentec supply soundproofed air intake and gas exhaust. This in addition to personnel and large equipment doors that are sounproofed, vacuum sealed and explosion rated.

Often, using only thick concrete for the cell walls & roof is just not good enough for noise contrtol. Acoustically treated composite walls & roof are used by Silentec for optimum cost/benefit. And when combined with the rest of the acoustic package,  low noise levels are achieved in real life. In full compliance with workplace and environmental noise regulations and standards.

Silentec is proud of always achieving the required noise performance.
