The science of interior space acoustics essentially consists in creating adequate acoustic conditions that are necessary for speech and music reception in spaces. The intended use of a particular interior space implies the use of specific acoustic quality criteria which, in turn, are related to respective levels of speech intelligibility. Enclosed sports facilities, such as gyms and indoor swimming pools, are spaces where speech intelligibility and noise level determine, to a large extent, the working comfort or even the safety of occupants. The use of acoustic treatment is often a necessary solution, but in fact is rarely employed. In the paper it is presented a method which develop rules and criteria for the assessment of interior space acoustics in sports facilities, and in particular, the assessment of acoustic conditions in terms of reverberation time and speech intelligibility in enclosed sports facilities, with particular consideration given to school gymnasiums. Presented method increases an accuracy and clarity of the criteria used to assess the acoustic properties of sports facilities. The goal of it is to raise designers' and facility owners' awareness of acoustical problems in such spaces, and of the necessity to apply acoustic treatment.
