The paper presents the research studies carried out on the reverberation time of rooms, in terms of theoretical aspects and applicability potentials. Over the last century a very large number of scientists have been attempting to work out models describing the reverberation time in enclosed rooms. They have also been trying to apply these models for the description of various acoustic parameters of the interior, i.e. the intelligibility of speech, clarity, articulation, etc. In fact, all these models are based on the Sabine’s statistical method. The paper presents the work of the scientists working on this problem, together with prospective applicability potentials. Such a review may be helpful for researchers, designers or architects involved in the discussed subject.
According to the psycho-lexical approach in the taxonomy of individual differences, those interpersonal differences, which are the most important for social functioning of individual, have been encoded into natural languages. Therefore by analyzing the lexicons of interpersonal differences, it is possible to identify structures of their descriptions. Application of the psycho-lexical approach in the field of psychology of individual differences lead to obtaining the relatively high consistency regarding scientific taxonomy of personality traits. Also models developed on this basis meet the most important criteria of goodness of the psychological structural models. As a result, the accumulation of knowledge about person’s psychological functioning have been intensified. The aim of the article is to present the specificity of lexical studies and their taxonomical potential for social sciences, as well as key threats and limitations, based on experience of previous psycho-lexical research.
