2.1 The maximum noise levels in the Guidance Notes
are given to:
- protect seafarers from noise levels which may give rise to noise-induced
hearing loss
- provide an acceptable degree of comfort in rest, recreation and
other spaces
- provide conditions for recuperation from the effects of exposure
to high noise levels
- provide safer work places by facilitating speech communication
and hearing of alarms in control stations, navigation and radio spaces,
and manned machinery spaces.
