Abstract
This paper analyzes the effect of exposure to noise among industrial workers in Nigeria to discover the level of exposure to noise that causes auditory defects or noise-induced hearing loss (NIHL), this paper primarily covers the evaluation of hearing impairment and its severity on exposure to loud sounds (acoustic trauma) and the role of hearing protective devices for industrial workers for prevention of Noise Induced Hearing Loss (NIHL). The paper also discusses the findings and guides as preventive methods for such industries. A total sample of seventy (70) workers were selected from three (3) manufacturing industries for this study. This study revealed a statistically significant difference in the hearing threshold within the selected industries over the selected period of time relating to the theory of excessive noise present in a given environment tends to affect people or in this case study employees hearing if proper hearing protection isn’t used for prolonged hours or time, the study also surveys the various effect of noise on human health including various steps of noise control in such settings.

Summary
It has been established that noise could lead to increased accident and loss of productivity in industries but, what is considered noise? Noise as an unwanted sound is considered unpleasant, loud or disruptive to hearing. Noise can be viewed in terms of intensity or amplitude and frequency [1]. Sound/noise levels are measured in units as decibels (dB). To determine the sound pressure level (SPL) in the atmosphere or a given space sound meters are used.
