European journal of environment and public health(2020)
摘要
This study was conducted basically to evaluate the noise dB(A) levels in primary and secondary schools within Otolo area of Nnewi, Anambra State, Nigeria. A total of eight (8) randomly selected schools (four primary and four secondary schools) were assessed. Noise levels in the classrooms and school playgrounds of the schools were measured using a factory-calibrated sound level meter. Results of this study revealed that the noise levels of classrooms and playgrounds of the schools selected for this study were in the range of 78-92 dB(A) and 61-97 dB(A) respectively. These levels were significantly above the World Health Organization’s recommended classroom and outdoor/playground noise levels. This study creates awareness on the implications of noise in schools and learning centers, and also promotes a simple method for regular assessment of the noise levels in these environments.
