Abstract
Model simplification is an important step in room modelling for acoustics simulation. Various simplification algorithms were previously suggested. However, they are highly demanding methods, which are more suitable for large complicated spaces. As this paper focused on small size open-plan office (OPO) spaces, basic modelling and manual simplification processes were used. The aim is to find the optimum level of model simplification through a manual reduction in number of surfaces. Parallel to this aim, the objective is to examine the effects of the change in model detail level on selected acoustical parameters in six OPOs. Construction of models started with the most detailed model. Simplified models were developed by gradually reducing the number of surfaces. Simulation on RT, STI and decay in SPL were done and compared to the measured data. The study found that models with up to 80% reduction in number of surfaces can still produce plausible simulation results.

How detailed or simple should the spaces be constructed for the purpose of acoustic simulation using ODEON Room Acoustic Software? And do these discrepancies in the model detail level affect the simulation results of the acoustical parameters? the aim of the study is to find the optimum level of model simplification through the simple method of manually reducing the number of surfaces
It can be observed that model 5 to 8 from most of the open-plan office (OPO) exceeded the maximum reverberation time (RT) relative difference of 10% applied in this study
Summary
Architecture uses visuals as its ‘tools of the trade’ to convey ideas (J. Schroeder et al, 1996). This process demands meticulous effort and the process of producing aesthetically appealing visuals is often time consuming
