In contemporary architecture, sound comfort is a key concept and issues such as noise pollution, sound clarity and suitable sound distribution have a special place in architectural spaces. Therefore, sound clarity and suitable sound distribution in studios are the themes considered in the present study. In studio space, appropriate reverberation time is of great importance in creating sound clarity. All architectural elements in a studio play an effective role in achieving optimal reverberation time. With the aim of recognizing acoustic properties of substances, materials and physical form, installations, insulation, and location in architectural space, three studios of Jam-e Jam radio were investigated as case studies. This study is a mixed research conducted by means of qualitative analysis method. By using logical argumentation and performing simulation in AutoCAD and ODEON softwares, indicators affecting optimal reverberation time were calculated. The available reverberation time was measured using the 2260 investigator device, and calculated with Sabine's Damping Equation. Then, the obtained values were compared with Odeon's tables. The results showed the reverberation time of 0.29-0.3 seconds at a medium frequency of 500 Hz for Studio No.2. This value was close to the standard one, showing the validity of using a suitable geometric form, high absorption materials, and the lack of vibration of mechanical and electrical equipment to achieve optimal reverberation time without secondary acoustic interferences.
