Abstract
A various kind of studies regarding ship noise are being carried out today. Nippon Kaiji Kyokai started studies more than fifteen years ago, and published the results in the form of guidance. Moreover, to deal with rationalization of ship noise, the authors have developed a computer program (hereinafter "KNOISE") to estimation noise levels in the accommodation spaces and engine room of a ship. KNOISE has an excellent user interface offering ease of operation, reduced data input through the use of standard tables, and an interactive data input system. Accordingly, in order to examine the validly of KNOISE, the authors have carried out to make a comparison between measuring data and results of calculation. This paper briefly outlines KNOISE and its development until now. The efficacy of "KNOISE" is inspected through a detail analysis of the measured data and numerical investigations.
