The growing focus on working conditions and comfort for
the crew has resulted in stricter requirements for shipboard
noise and vibration levels.
Head-pounding vibration is no longer acceptable on board.
Tasks at sea demand precise performance, and it is essential
that crews are alert and focused on their work.
Innovative solutions are needed to make ships an attractive
workplace.
Outstanding shipping companies that set the trend in
the market insist on low-noise vessels.
This lowers risk and promotes safety, boosting the quality
and efficiency of the entire operation.
Crew cabins and offices
on merchant ships.
Specific work areas on
board, e.g. wheelhouse,
control rooms.
General work areas.
Partly based on noise statistics
and physiological data.
Effects in the form of
annoyance and stress
(subjective effect on
sleep quality).
Speech becomes less
intelligible at higher levels:
70 dB(A) requires a raised
voice. Annoyance and stress
start to affect the performance
of demanding tasks.
Levels above 75 dB(A) give
clear indications of reduced
performance for demanding
tasks. Above 85 dB(A): High
probability of reduced
performance.
