This presentation is largely based on a review on modelling from LMS, a Belgium company based in Leuven [1]. The New Zealand Acoustical Society aims to be a source of knowledge for the community and provide useful information regarding acoustic issues that influence our daily life. But this is not only about telling people what is acceptable according to which code, but also informing everyone about the tools that exist, not only in underlining danger, problems and annoyance, but also in providing alternative solutions. This paper presents a brief overview of computer modelling methods to predict the acoustic and vibroacoustic behaviour of interior and exterior fluid regions and their interaction with structures, geometrical and energy based methods (acoustic ray< tracing, statistical energy analysis, etc) and wave
