Active noise reduction (ANR)

Countering cavitation as one of the main sources of noise in transverse thrusters, we can effectively reduce the volume by 15 dB (A) through active noise reduction. Tthe targeted injection of air reduces noise and vibration in both the vessel and the water.

Passive noise reduction

Structure-borne noise and ambient noise caused by mechanical vibrations can be effectively reduced by installing an elastic foundation for gears, propellers.
