Standards Development
This proposal provides the measuring method of cabin noise caused by ventilating and air conditioning system in real ship environment, and specifies the detail measuring equipment, measuring method, survey report and so on. It is suitable for guiding acoustic professionals to carry out cabin noise measurement caused by ventilating and air conditioning system of ship and marine engineering equipment.
In order to improve the comfort of the crew and passengers of ships and marine engineering equipment, in recent years the International Maritime Organization (IMO) and various classification societies have put forward more and more stringent requirements for noise on board ships. The Norwegian Petroleum Standardization Organization has put forward the air noise limit requirements for the cabin under the condition of individually opening ventilation and air-conditioning systems in the NORSOK STAND S-002 "Working environment".
However, there is a lack of measurement methods for cabin noise caused by ventilation and airconditioning systems under the conditions of real cabin environment in the world. Therefore, this proposal aims to provide corresponding measurement methods for acoustic professionals to carry out real ship measurement.
