摘要
This study assesses noise pollution levels of furniture industries in Adamawa State, Nigeria. The state is located between latitude 9 111 North and longitude 12 201 East. The study is imperative due to the detrimental effects of noise on the furniture workers and surrounding communities. Three (3) study locations endemic to furniture industries, namely: Yola, Mubi, and Ganye were randomly selected for the study. The fourth (4th) location was void of any industries, and served as the Control. At each location, the noise levels were obtained using a portable Digital Volcraft Sound Level Meter, Model 33-2050. Two (2) seasons (wet and dry) noise levels readings were carried out in the months of August (wet) and February (dry). The readings for the two seasons were taken at hourly intervals of 8 hours between 9.00am and 4.00pm for 5 days at the 4 sampled locations. The obtained values were compared with those of National (Federal Ministry of Environment) and International (World Health Organisation) regulatory limits. Analysis of Variance (ANOVA) statistics was used to analyse the obtained data, in order to test for the significant level of the noise pollution between the sampled locations. Results of the average energy equivalent level of the A-weighted sound over the time period (LAeq,T) during the dry season showed that, Yola has the highest noise pollution of 78.29 dBA, followed by Mubi (64.76 dBA) and Ganye (63.22 dBA). The trend was similar during the wet seasons, but with lower values as follows: Yola (76.52 dBA), Mubi (61.43 dBA) and Ganye (60.62 dBA). Significant difference of noise level was attained between Yola and Mubi, as well as Yola and Ganye (p<0.05). Significant difference was however not obtained between Mubi and Ganye. Highly significant difference was established between each of the 3 industrial locations (Yola, Mubi, and Ganye) and the Control (p<0.01). Findings also revealed that Yola industrial location noise level exceeded the International limit of 75 dBA. The use of ear muffs by the workers and building enclosures for the machines were recommended to reduce the noise levels, especially in Yola industrial location. The industrial workers in particular and the surrounding communities will benefit from these measures. The government may enforce these precautions through legislative policies.
