Conclusion
We conclude from this study that the market mill workers
had possible a NIHL with a prevalence of 25% in the better
hearing ear. A large majority of mill workers did not use
any hearing protective device even though 54.5% of them
exhibited solid knowledge on the effects of noise on health.
Self-reporting of hearing loss was unreliable.
Further research in this fi eld should focus on impact of
preventive measures on prevalence of sensorineural hearing
loss among small scale traders working in other self-employed
industry with unregulated work place noise.
