The evaluation of noise and vibration in the educational environment is the effect of traffic noise that can be exposed during school operation in the case of a new school and the effect of noise at the construction site during construction in the case of an existing school. The evaluation criteria apply the environmental standards of the Basic Law for Environmental Policy and the regulatory standards based on the Noise and Vibration Regulation Law for noise and vibration in the teaching area. In addition, when measuring noise with a sound level meter, various factors interfere with the measurement values, such as the geometrical positional relationship between the noise source and the sound-receiving point (classroom), the structure of the classroom envelope, the size of the window, the sound absorption capacity of the classroom, the sound insulation performance of the window, the area of the open window, the noise incidence angle, inside air quality and air volume in addition to occurrence of unexpected variables. These factors are not at all accounted into the legal standards, causing the negative damaging influences to the members of the school, and significantly deteriorate the right to study and education. Therefore, it is necessary to review the indiscrepancies in noise standards and measurement methods prescribed by each law related to the school noise.
