Abstract
Environmental noise produces many negative impacts to people exposed to it. As a result of the strong biased factor in the sensitivity of noise, physical measurements of noise give only fractional representation of the real problem. Public opinion is one of the most reliable indices of the problem. Therefore, this paper presents the environmental noise impact assessment in Nsit Atai Local Government Area of Akwa Ibom State, Nigeria. Physical measurements of noise levels were made around people’s homes and offices by using the sound level meter (SLM), model WensnWS1361. The selected locations were market (MT), airport area (AA), roads/streets (R/S), churches (CH), road junctions/parks (J/P), workshops (WS) and schools (SH). The data obtained were compared with WHO standard levels. Based on the results of physical measurement, some major locations in the area were chosen as interview centres. Sources of noise like aircrafts, tricycles/motor cycles, cars, churches, children, animals, workshops/factories, lorries, compact disk sellers, traders and ships/engine boats, power generator and night clubs were presented to the interviewees. Here, the interviewees were asked to tick the sources of noise they were exposed to and to indicate how the noise sources affect them. The data obtained were analysed using Percentage Analysis Method. The results of the physical measurements show that all the selected locations had noise levels above the tolerant levels, while the results of the social survey reveal that there are many sources of noise in the area, The results of the noise bothers survey reveal that noise of aircrafts bothered only 42% of the respondents, while 60% were exposed to it. This Local Government Area forms part of the Akwa Ibom international airport area where an average noise level of 92.43 dBA was recorded. The result may be due to the fact that the airport is located a far distance from the residential areas. The people in Nsit Atai are exposed to the noise of lorries most. Here, lorry noise was heard by 77% of the respondents while 54% were bothered by it.
