Acoustic control in a multipurpose hall: The case study of Lala Mustafa Pasa Sports Complex, Eastern Mediterranean University, Gazimagusa - North Cyprus

ABSTRACT: In recent years, due to tight budgets, a large number of multipurpose halls have been constructed applying relatively inexpensive materials without regard to planning for noise control to mitigate loud, unpleasant, unanticipated, or undesired sound. Consequently, after construction is completed, noise issues are often proven within the spaces and render the initial purposes of the structure unattainable. In this study both qualitative and quantitative research methods are used to identify the acoustics problems, its sources, effects, and control. The research revealed that the Rapid Speech Transmission Index [RASTI] and Reverberation Time [RT] of the Hall was 0.34 and around 4.5 seconds respectively, which indicated that EMU, LaLa Mustafa Pasa Hall in North Cyprus is having speech intelligibility and echo problems. The study would not only edify potentials and professionals on the importance of acoustics as a major factor in building design, but also address the common solutions to resolve noise in multipurpose spaces. This multipurpose hall is expected to be used for various activities such as music functions, sports and speeches. Against this background the study highlights the fundamentals of sound and room acoustics including noise from interior and exterior sources as well as looking into the possible economic solutions that can be taken within the building to attenuate noise. Suggestions and recommendations to this effect are given at the end of this research to guide any institution or company and all those who may wish to build a proficient and acceptable multipurpose hall in the future.
