Hearing loss in the left ear was 2.8%, in the right ear was 4.2% and in both ears was 17%. Mild hearing loss was 20%, moderate was 4% and severe was 0.1%. Hearing loss at 1KHz was 3.4%, at 4KHz was 10.9% and at both frequencies was 9.7%. There was a relationship between age group, gender, working experience, field of work, and job position with hearing loss. Conclusions: The rate of hearing loss in workers who come for periodic occupational health examinations at the Can Tho City Center for Disease Control is quite high.
