Evaluation of Noise Levels in Oil Mill Market and Its Environs, Port Harcourt, Nigeria

Abstract

Noise in market places can be a matter of public concern to traders and other close residents. Exposure to excessive noise has the ability to cause both physiological and psychological effects in humans. A systematic noise survey was conducted at different locations within Oil Mill Market and Eleme Junction in Port Harcourt, Rivers State, Nigeria. Modelling of noise levels within the market area is presented. A cumulative noise level of 108.6dB (A) was obtained along East-West Road between Oil mill market and Eleme junction; Eleme junction showed cumulative noise level of 105.4dB (A); also, Elelenwo by Oil-Mill market showed noise level of 103.8dB (A); while, Oil-Mill Market showed cumulative noise level of 108.2dB (A). Computed mean noise value is 109±3dB (A), computed Leq index is 123.6±2.3dB (A), while computed noise pollution level is 117.1dB (A). Findings showed that use of grinding machines and generators within the market accounted for 27% of noise within the market; mobile sellers contributed 26%; while vehicular movement along the East-West highway and Eleme junction constituted 19% of the noise produced in the area. High noise pollution prevails within the market environment withpotentialhealth effects on traders and the public. State and/or Local Governments should carry out awareness campaigns among traders on the effects of noise on their health. Noise control by-laws or regulations should be enforced so as to regulate the activities of mobile advertisers or sellers.
