Active vibration control for underwater signature reduction of a navy ship [PDF]
, 2010 Dutch navy ships are designed and built to have a low underwater signature. For low frequencies however, tonal vibrations of a gearbox can occur, which might lead to increased acoustic signatures. These vibrations are hard to reduce by passive means.
