Comparison of Outdoor and Indoor Noise Levels in Schools

Summary/Abstract: The purpose of this research is to compare the noise levels both outdoors and indoors of the schools. This research is a descriptive (supplementary) type of research which was done in 3 primary schools, 3 secondary schools and 4 high schools in Orhangazi-Bursa. In these schools, ‘Bruel & KjaerHand-held Analyzer Type 2250-L’ sound meter was used to take sound measurements. Determining the noise levels was done during break time and lesson time both outdoors and indoors of the schools. Findings demonstrated that the indoor noise levels of all schools were significantly higher than the values recommended in the regulation. When the outdoor noise levels are examined, it is seen that only one school is below the recommended values. Outdoor and indoor noise levels of central-city schools were higher than the noise levels of schools far from city-center. According to these findings, new schools need to be constructed in areas where the noise levels are low, far from the center of the city. There is also a need for sound insulation in all schools. Comparisons of school types at different levels found that the noise level of primary schools was significantly higher than the others. These findings indicate that a program is a needed to detect and design methods for controlling excessive noise in all school types.
