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.
