Application of the technique of singular value decomposition (SVD) for analysis of acoustic properties of sacral objects has been presented in the paper. Previous researches by means of the SVD technique were related to the simplified calculation model basing on a three-index observation matrix. The next stage of researches presented in the paper is an attempt of decomposition of the observation matrix containing five partial indices of the index acoustic assessment of sacral objects. The matrices obtained through the SVD decomposition have been used for calculation of weights of partial indices applied for the global assessment of acoustic quality of the sanctuaries. The comparison of acoustic assessments of the sanctuaries by the global indices containing traditional weights and the weights obtained by means of the SVD technique has been performed.
