summary 
During the modelling, because of the sometimes complex architectural shape of halls, we were forced to introduce simplifications in order to carry out calculations and simulation operations on these halls, as the calculation software requires plane surfaces. This paper presents a developed tool adapted on a CAD modelling system (AutoCAD), which defines an “average limits” of the model simplification operation in order to control and diminish the falsification of calculation and simulation results on this model, such as the architectural acoustic simulation.
The process of the elaboration and the adjustment of the simplified models of the Grand Theatre of Bordeaux (GTB) based on acoustical measurements and their calculation results are described in detail in a previous article (Kouzeleas and Semidor, 2001). The analysis process of the consequences of the hall model simplification on the acoustical simulation results and the applied simplification methods are described in a PhD thesis (Kouzeleas, 2002).
This article is based on this analysis process in order to apply it on several simplified models of the Amphitheatre of the Architecture School of Bordeaux (AmphiEAPB). The comparison in a CAD system (AutoCAD) of the acoustical calculation results and the areas after simplification of the simplified models of these two halls made with AutoCAD, via the developed tool adapted on the AutoCAD, permit to define a “limits average of a hall model simplification” before the falsification of these calculation results.
