The active mountings are based on the noise-cancellation principle: they create sound waves with the same amplitude and the opposite polarity to the original structure-borne waves of the engine. In this way, noise and anti-noise cancel each other out to a large extent.

The Tognum subsidiary MTU Friedrichshafen signed a contract on the exclusive distribution of active engine mountings with the companies Paulstra and Stop-Choc. The jointly developed system, which MTU has trialed on test benches and in ships, reduces the structure-borne noise emitted by diesel engines. This innovative concept of active mountings has been developed through to product maturity for yachts and naval ships.
