| Title | Common Noise Interference on Campus – A case study in an Elementary School in New Taipei City | ||
| Keyword | |||
| Abstract | Noise complaints have continued to increase yearly according to statistics from the Environmental Protection Administration (EPA), Executive Yuan. This is also the case in schools where teachers and students alike have experienced increasing noise in their surroundings. Tranquility in schools is of primary importance for teaching and learning. However, school environments have changed and are gradually being saturated with excessive noise levels. This disadvantages teaching and learning, as well as harms the health and minds of teachers and students. The aim of this study is to examine common noise sources and sound levels in schools. The study targeted an elementary school in New Taipei City in which the audiometers have been set up to measure sound levels in three classroom locations in three periods, namely mornings, afternoons and evenings. To understand whether teachers and students usually teach and learn under a high noise level environment, data collected through audiometers has been processed in a way of analysis and statistics by the soft program, Excel, and then use diagrams to show the changes of classroom noise levels in different background sounds. Results showed that the Equivalent sound level (Leq) landed between 70 and 80 dB(A) while all the school teachers and students conducted activities in the morning. The Leq dropped to between 55 and 65 concerning to each locastion and period while only 3th grade to 6th grade students attended classes in the afternoon. In addition, due to there being no class activities at night, the Leq decreased slightly to between 52 and 58 and this was affected by the activities held in an MRT station near the campus. The main cause of Leq rising to up to 80 dB(A) was construction noise. Thus, it can be seen that as well as noise from school students, one of the major noise sources on campus is construction noise. In addition to noise from the surrounding neighborhood, another finding is that the poor design of school buildings, bells, alarms, and broadcasting increase the sound levels in the school. Exposure to high Decibel environment without any protection for school teachers and students affects their body and mind, and hearings as well – no matter if it is an impulse noise or continuous noise. |
