2.1 Where practicable, any engines or machinery
producing noise levels in excess of the limits set out in section 4.2 of the Code should be installed in
compartments which do not require continuous attendance (see also
paragraph 6.1 of this appendix).
2.2 Accommodation should be sited both horizontally
and vertically as far away as is practicable from sources of noise
such as propellers and propulsion machinery.
2.3 Machinery casings should, where practicable,
be arranged outside superstructures and deckhouses containing accommodation
spaces. Where this is not feasible, passageways should be arranged
between the casings and accommodation spaces, if practicable.
2.4 Consideration should be given, where practicable,
to the placing of accommodation spaces in deck houses not in superstructures
extending to the ship's side.
2.5 Consideration may also be given, where applicable,
to the separation of accommodation spaces from machinery spaces by
unoccupied spaces, sanitary and washing rooms.
2.6 Suitable partitions, bulkheads, decks, etc.,
may be needed to prevent the spread of sound. It is important that
these be of the correct construction and location in relation to the
source of sound and the frequency of the sound to be attenuated.
2.7 Where a space, such as a machinery space,
is being divided into noisy (not continually manned) and less noisy
(capable of being continually manned) spaces, it is preferable to
have complete separationfootnote.
2.8 It may be advisable to provide sound absorbing
material in certain spaces in order to prevent increase of noise level
due to reflection from partitions, bulkheads, decks, etc.
