| dc.description.abstract | This study measured the ambient noise levels in twenty schools (both primary and secondary) in Zaria to document the level of noise in the schools, variation that occur during the day and its effects on teaching and learning process. Noise levels (A-weighted decibels) were measured using Extech 407732 sound level meter. A total of 574 questionnaires were administered, which involved 419 students and 155 teachers, to assess occupational and teaching related outcome. These schools were chosen to cover heavy and light traffic roads, as well as those submerged into residential buildings. The questionnaires were validated by experts in the Faculty of Education and tested for its internal consistency using Cronbach alpha (0.848 for teachers and 0.700 for students). Manual traffic count was carried out around schools that identified traffic noise as their main source of noise exposure. The data obtained was used to compute Equivalent Continuous Level (Leq.), Noise Pollution Level (LNP), Noise Climate (NC), and Percentile Noise Levels (L10, L50, L90). The result shows that the indoor and outdoor noise levels in primary and secondary schools is high ranging between 71.5 - 95.9 dBA, 59.1 - 98.7 dBA (Indoor) and 75.5 - 93.1 dBA, 70.4 - 98.5 dBA (Outdoor) respectively. The traffic noise index (TNI) ranged between 64.3 - 122.7 dBA and 54.5 - 123.1 dBA for primary and secondary schools respectively. These values exceeded the World Health Organization (1980) and National Environmental Standards and Regulations Enforcement Agency (2007) noise level limit of 35 dBA and 55 dBA for indoor and outdoor noise levels in academic environment. At 95% confidence level, the mean of the paired samples are the same. There was no statistically significant change in the Leq. from morning to afternoon in the schools (P = 0.299 and 0.980). Similarly, there was no significant difference in the level of noise pollution in Primary and Secondary Schools (P = 0.895). There was no significant difference in the traffic, indoor, and outdoor noise levels. Over viii 94.2% of the teachers complained that noise affected their teaching and 92.6% of the students reported that noise affected their learning ability. They reported tiredness, lack of concentration, communication interference, voice masking, low speech intelligence among the major problems. About 55.5% reportedly said they are not aware of noise pollution. It was concluded that students and teachers in public schools in Zaria are exposed to high decibel of noise. This affects the process of teaching and learning. It was recommended that noise barriers should be installed into the buildings and overcrowding in classrooms should be avoided. | en_US |
