7.2.3 Structure-borne noise
The vibrational energy is propagated via engine structure, bedplate flanges and
engine foundation to the ship’s structure, which starts to vibrate and thus emits
noise.
The sound pressure levels in the accommodations can be estimated with the aid
of standard empirical formulas and the vibration velocity levels.
