摘要
The purpose of this research is to investigate the effect of low-absorbent and reflective building materials(gypsum board)on the acoustic parameters of the room,depending on the type and structure of the cladding.Although gypsum board(dry cladding system)is widely used in music schools,concert halls,gyms,recording studios,their sound-absorbing properties are generally under-considered,with the main focus on their sound insulation properties.More than 10 types of boards comply with the EN520 standard;each type of board has its own sound-absorbing parameters and is used in different systems.The essence of this study is to evaluate the influence of EN520 plates on the acoustic parameters of the room:Rt;C80 and RASTI.This study does not cover all types of EN520 boards and possible combinations of their applications.This study compared four different wall-cladding systems-single-and double-layer cladding,with and without the use of stone/glass wool in order to determine acoustic properties compliance to function for sport and teaching room space.
