Analysis of Noise pollution level in Enugu campus, of the University of Nigeria

Abstract

Noise is sound of any kind that is undesirable and unwanted as part of the environment under consideration. It is one of the types of pollution that have great impact on our health and wellbeing. The occurrence of noise in our environment is increasing daily because of growing population and industrialization. Noise pollution have great consequences on our social and economic lives especially in teaching and learning environment, which is presumed to be in silent zone. It is worth investigating whether environment in which teaching and learning take place is in quiet condition? The aim of the study was to analyze the level of noise pollution at different locations in the University of Nigeria, Enugu Campus. The Nigeria Standard noise level for higher education institutions and hospitals should be 60 dB for day and 50 dBA for night. The Noise levels dBA was measured with the help of noise meter at 14 points and at a height of 1 m above the ground level within the campus at three different times (6–8 am, 12–2 pm and 4–6 pm). The total Leq noise level in the University of Nigeria, Enugu Campus is 70.94 dBA which is above the level recommended for educational institutions. The period of intensity of noise was recorded during afternoon, morning and evening respectively. This rate of noise level during the day is high and unsuitable for teaching-learning process. Therefore, university management should take proactive measures to regulate noise pollution within the campus and indeed, other university campuses in Nigeria.
