ANALYSIS OF INFLUENCING FACTORS THAT CONCERN THE UNCERTAINTY OF MEASUREMENT OF SOUND INSULATION IN SMALL TRANSMISSION ROOMS

This paper is focused on analysis of the Laboratory of Building Acoustics 1 (the Faculty of Civil Engineering of Slovak University of Technology in Bratislava (STUBA)). The aim of the presented work is to show a quasi-complete analysis of the given laboratory, that consist of definition of its limits, summarizing weak points and proposal for optimized measurements. The paper consists of two main parts (i) the assessment of sound field in the receiving room and (ii) the determination of the maximal measured sound insulation in the transmission suite. Soon, the fundamental reconstruction and innovation of the laboratory will be undertaken. Therefore, all achieved results and information should be implemented into the new project
