The mechanisms for successful sound design in educational spaces to achieve acoustic comfort and their impact on academic efficiency: (The study of auditoriums in universities)
Abstract
AbstractArchitects prioritize designing different buildings to maximize the utilization of natural resources such as natural lighting, natural ventilation, and renewable energy. However, some individuals overlook the focus on architectural acoustics, which deals with controlling sound transmission from the outside to the inside or improving sound diffusion within spaces, and the negative impact that improper design can have on human health. According to the World Health Organization (WHO), its guidelines on environmental noise were last updated in 1999, affirming that noise has negative effects and serious health consequences, including hearing loss, cardiovascular diseases, and a decline in physical and mental performance. Therefore, the research addresses a scientific methodology that assists architects in designing spaces that achieve sound comfort, with a particular focus on educational spaces, including a case study on lecture halls in universities. Introduction: Successful acoustic design of educational spaces is considered crucial to achieving sound comfort, and to accomplish this, it is necessary to study the users' needs alongside external and architectural factors, such as the types of noise that affect buildings, whether they are external or internal, and anticipate external noise levels using site analysis and determining the performance requirements of the building through simulation programs. Subsequently, materials are selected in collaboration with architectural engineers after studying their characteristics and their ability to isolate or prevent sound transmission and determining the role they play in making improvements to the design. There is a diverse range of available materials that assist in achieving sound comfort
