Abstract:

A procedure for designing ventilation systems for naval vessels is needed. It should contain the results of the latest research in the area of air conditioning and ventilation noise. An investigation of this was made with the objective of producing a comprehensive design guide. It was concluded from the results of a literature search and conferences with designers of naval vessel ventilation systems that the Naval Applied Science Laboratory NASL Report of Development of Estimating Method for Predicting Noise Originating in Air Conditioning Systems on Naval Vessels provides a design guide that will generally satisfy the shipbuilders need. The NASL report, however, lacks a procedure for predicting the amount of noise transmitted through the walls of a duct into the space through which the duct passes. Designers indicate that in some instances a wall providing higher transmission loss than that now used is needed. This problem is being investigated. Author
