Measurement of noise on board vessels
This standard covers the measurement and assessment of noise levels on board ships, including identifying noise sources, the height of noise levels, and evaluating the risk to crew members. It also guides noise-reducing measures, such as noise barriers, vibration isolation, and sound-absorbing materials.
Measurement of vibrations on ships
Provides guidelines regarding vibration in its various parts and analyzes the ways to measure the vibration of different onboard equipment, structural vibration, vibration on the ship’s propulsion machinery, and in different areas onboard assessing their habitability.
Underwater acoustics
Which sets out methods for measuring underwater sound from ships, the measurement of sound radiated from a ship’s hull, machinery, propeller, and sound transmitted through the water. It also specifies the instrumentation and procedures for making measurements, including the measurement of sound pressure levels and frequency spectra.
Measurement of airborne sound emitted by vessels on inland waterways and ports
Sets the conditions for obtaining comparable measurements for sound emitted by vessels. It applies to all vessels except recreational crafts under different rules and with a reference distance of 25m
