Worker’s Response (Attitudes) Towards Exposure to Steady-State Broad-Band Industrial Noise in Jos

Abstract

Noise sound pressure levels in some companies/industries in Jos were measured and the attitudes of the workers to the noise were assessed in the same companies/industries. The objective physical measurements showed that the noise was steady-state, broad-band and continuous. The equivalent continuous noise levels in most of the companies were more than the 85dBA Time-Weighted Average. The Pearson correlation coefficient for noise rating and equivalent noise level γ1=0.735 and the Pearson correlation coefficient for noise annoyance and noise level γ2=0.944 , both show strong positive correlations between objective and subjective assessment of noise. This implies that the higher the noise level, the higher the noise rating and the higher the annoyance.
