Evaluation and Improvement of Reverberation Time in the Current Enclosed Spaces with Speech Action

There are subjective and objective acoustic parameters in the creation of performance for speech action room acoustics. Control reverberation time affecting is a main parameter In this study, assessment TOBB Twins Headquarters Reception Hall, which current enclosed space with square plan flat floor, has been performed as case study. The evaluation focused on relationship between interior surface absorption. Primarily, was determined according to international standard in-situ measurements space. found over reference value range. Models have developed use materials reduce time. acoustics parameters, times models using Ecotect v.5.20 Odeon 14.00 simulation programs determined. model optimum obtained constructed. After construction, made again. As result effect absorptions improvement spaces floor evaluated. Suggestions control reflective absorption properties all surfaces accordance
