Résumé

The risk of much increased rates of occupationally acquired hearing loss must be met by strong preventive measures in engineering and medicine in both developed and developing countries. Hearing assessment of the respondents was done by a trained Technician using a pure tone audiometer in the Department of Otolaryngology, University of Calabar Teaching Hospital, Calabar using the audiometer. The frequency of the audiometer was varied from 64 Hz to over 8000 Hz. Amplitude was varied by 5 dB increments. The oscillator was used to change pitch so that a range of sounds can be tested. The effects of exposure to loud noise on hearing of people in Calabar were assessed by comparing the hearing acuity and subjective responses of respondents in the high noise zones with that of respondents in the low noise zones.
