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 TimeWeighted Average. The Pearson correlation coefficient for noise rating and equivalent noise  level   and the Pearson correlation coefficient for noise annoyance and noise level   , 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.
