Background Noise Level in Niger Delta University Water Factory

Abstract

This research work is aims at determining the noise level in the Niger Delta University water factory for both operational and non-operational as shown in the various tables. Figure 1 and figure 2 shows the bar charts of the various noise levels of the water factory when the factory was in operational and non-operational. Figure 3 is a bar chart of the combine operational and non-operational noise levels in the water factory. In figure 1, the noise level is highest at the finished product store-room with a noise level value of 113.7 dB(A) as against 80.5 dB(A) in the bottle water store-room. Figure 2 indicate when the factory was non-operational the highest noise level is found in the payment room with a noise value of 67.4 dB(A) and the lowest noise level in the bottle water packaging room of noise value of 35.4 dB(A) this can be due to human activities that are taking place in the payment room. Figure 3: Shows the shows the bar chart for both operational and non-operational noise levels of the water factory, For the operational the finished product store-room has the highest with 113.7 dB(A) as against the non-operational in the bottle water packaging room which has a lower noise level value of 35.4 dB(A) this is compare to the permissible limit as recommended by WHO of 75dB(A) for eight (8) working hours.
