Today, although acoustic designs for different purposes are not realized in sports halls designed for sports activities, these halls are widely used for various events such as conferences and concerts. In this study; The main activity area in the Beşirli Central Tennis Court building, which was built for sports activities within the scope of the European Youth Games in Trabzon Province, was evaluated in terms of acoustics for different functional uses by computer simulation method. First of all, 3D models were prepared for the current conditions of the main sports event areas according to different audience occupancy rates. Then the models were transferred to the simulation program to evaluate the objective parameters of the sound. After obtaining the objective parameter values of the sound, 3D models of the hall were prepared again with the soundabsorbing mechanisms placed between the existing steel structural system on the ceiling plane of the hall, designed for the realization of sports, music and speech activities in the sports activity areas. The prepared 3D models were transferred to the ODEON V10 program and the simulation process was repeated. As a result of all simulations, the values of the objective parameters of the sound obtained for indoor sports activity areas were compared and evaluated with each other and the accepted optimum value ranges.
