The purpose of the Code is to limit noise levels and to
reduce seafarers' exposure to noise, in order to:
-
.1 provide for safe working conditions by giving
consideration to the need for speech communication and for hearing
audible alarms, and to an environment where clear-headed decisions
can be made in control stations, navigation and radio spaces and manned
machinery spaces;
-
.2 protect the seafarer from excessive noise levels
which may give rise to a noise-induced hearing loss; and
-
.3 provide the seafarer with an acceptable degree
of comfort in rest, recreation and other spaces and also provide conditions
for recuperation from the effects of exposure to high noise levels.
