Thruster noise is a major problem for crews. The stress and discomfort it causes may threaten both performance and safety on board.
Quieter manoeuvring means better sleep, improving the alertness and efficiency of the crew.
Passengers enjoy a new degree of comfort.
Noise levels of 75-88 dB(A) are typical in cabins next to and above conventional tunnel thrusters. Brunvoll’s advanced technology can cut this by up to 15 dB(A). Combined with other measures, noise reductions of up to 20-25 dB(A) have been verified.
Brunvoll pioneered the LowNoise thruster in 1977. Today, Brunvoll is recognized world wide as the major supplier of effective LowNoise thruster solutions.
