The current document describes the research work carried out in the Applied Acoustics Department of Chalmers University of Technology (Gothenburg, Sweden). It corresponds to the study of two acoustic simulation softwares that are, in the moment of the project, under tests The present work is one of them, focused on the “Modelling of Open Plan Offices”, which gives the name to this Bachelor Thesis, conducted in Escuela Politécnica Superior of University Carlos III of Madrid. The main objective of the project is to prepare, perform and analyse the modelling and simulation of three Open Plan Offices, through the acoustic simulation tool developed by Aachen University, RAVEN. This implies the initial field measurements in the real rooms, the posterior 3D Modelling, and acoustic adjustments, as well as the auralizations of the selected sounds. As part of the tests, it is necessary an evaluation of the plausibility of the tools employed for the simulations, hence one real listening experiment was designed. The outcomes obtained are promising as the answers of the participants have ranked the simulations in high positions, although for some cases the results can be improved. It is also done a socio-economic study, where the advantages of the usage of this kind of tools in real spaces is analysed. The impact this may have on the design of Open Plan Offices is also considered, as the wellbeing and comfort of the employees influences not only their adequate productivity at work but also their health.
