The aim of this paper is to quantify the consistency of the valuation quality assessment of the acoustics of the concert halls by subjective assessment surveys. We have done the comparison both among experts, as in the case of one expert who performed the assessment at two different times. To carry out this work it is necessary to use a system of immersive virtual reality, C.A.V.E. (Cave Automatic Virtual Environment) that allows visualizing in 3D the simulated room and listen to the piece of music from different points of them through subsequent auralization of sound at these points. 3 rooms from Valencian Community have been simulated and the auralization of some pieces of music in different parts of the room has been performed. The results show that surveys provide very good intraobserver reproducibility, with differences around 5.2%, 95%CI [3.7% - 6.7%], whereas the concordance among experts is somewhat smaller, discrepancies can be established in 12.8% of survey items 95%CI [10.8% - 14.8%].
