An Example of Comparison of Internal Surface Materials for Room Acoustics in Conference Hall

Abstract

Conference halls are the places where speeches are made to give information to the community on a subject. Conference rooms are often preferred for presentations, project shows and many other activities. Due to the high number of listeners, the sounds are quite echoing. From these disturbing sounds, audience may be disturbed and the efficiency of the event may be reduced. In such environments, it is very important to regulate the acoustics of the volume and to use material. In this context; in the sample conference hall, the case of untreated perforated wood panels used and the case of currently used perforated gypsum panels, were evaluated and compared with the Odeon simulation program. reverberation time (T30), early decay time (EDT), speech transmisson index (STI),A-weighted sound pressure level (SPL (A)), definition (D50) parameters were evaluated. As a result of the study; perforated gypsum board and perforated wood panel usage in the existing hall; similar results were obtained in terms of volume acoustic parameters.
