A poluição sonora no ambiente escolar em São João do Piauí - PI: reflexos no processo ensino e aprendizagem

Abstract

Pollution resulting from excessive noise is characterized as noise pollution, which, although it does not remain accumulated, can cause harmful effects on health when exposed to it frequently, causing hearing discomfort, stress, insomnia, difficulties in concentration and memorization. These symptoms can affect the learning process. The objective of the present study was to analyze the decibel levels in two public schools in the municipality of São João do Piauí-PI to analyze the possible interferences in the teaching and learning process. To measure the decibel levels in schools, the decibel meter was used in fast mode, which captures faster sounds such as sound cars in progress. Three measurements were carried out with the classroom empty, during class and in the outdoor areas, courtyard and street. The main results found are related to the decibel levels inside the classroom that occur similarly to the external area, according to the measurements. In all measurements the averages of decibel levels were higher than recommended by NBR 10.152. Therefore, this excessive noise can cause different harmful effects for students in the classroom. Therefore, from this research we can see the need to awaken the academic community and the population in general about the harmful effects of noise pollution.
