Sažetak
This paper describes a case study aimed at improving the acoustical situation in the basilica in the town of Solin, Croatia, still under construction at this time. The architectural design of the basilica puts the emphasis on visual appeal, but no measures related to obtaining adequate acoustical conditions have been envisioned in the project. Given the importance of this particular place of worship, it is an imperative to achieve favourable and appropriate acoustical conditions in the basilica, and, consequently, good intelligibility of speech as the basis of any event to be held in this space. The measures required to achieve this goal were divided into two stages. In the first stage, acoustic treatment was proposed on the basis of calculations made in a dedicated room acoustics simulation software, based on the blueprints and expected finishing of the surfaces inside the basilica. Given the size of the basilica, it became clear that spoken word cannot reach all the listeners with adequate volume and clarity. Therefore, in the second stage a design solution was proposed for the sound reinforcement system to be installed in the main liturgical space of the basilica, taking into account both acoustical and architectural requirements that needed to be met. The required calculations were based on the room acoustics model obtained in the previous stage, and were made in the same software. The paper shows the results of selected calculations made for possible solutions for acoustic treatment and the sound reinforcement system. The criteria and limitations that played a role in choosing the optimal solutions for both are discussed.
