Rezonator effects of student cabinets used in classes

Abstract

Achieving acoustic comfort in high school is of great importance for increasing the quality of education. Due to the high number of students in classrooms, canteens, cafeterias, and corridors, the voices of young girls and young men are intense. Apart from that, HVAC systems, lighting fixtures, announcement systems, and electronic devices increase the background sound level and students communicate with each other with a higher sound pressure level. The conditions of use of the training areas require hygiene and materials resistant to vandalism. This necessitates the use of hard and smooth material, which increases the RT of the interior spaces. Different methods are being sought for ensuring the value of RT required to increase D50, C80, and S/N level in student-student-teacher communication in classrooms. For this purpose, different schools were observed in different sizes, covered with different materials and interior materials, and RT, EDT, D50, and C80 measurements, Lmax, Lmin, and Leq measurements w...
