| Summary: |
In the present investigation, 13 glass factory workers exposed to loud noise participated in the implementation and evaluation of a Hearing Conservation Program (HCP) during a period of nine years. The environmental conditions as
well as the hearing ability of the workers were assessed. At this point, the HCP was implemented , and 9 years later in 1996, it was evaluated. The training and Advancement Program of 826 man training hours was basic because it instilled an awareness in the workers which led to the implementation of measures to control exposure such as: the re-location of two work places in a less noisy area; the equipping of personnel with protective gear; the transfer of two workers to departments whith less noise, and the construction of a work stall. During the nine years of research, 72 audiometric tests whith an average of 5.5 audiodmetry per worker were made. The results of the corrective measures
taken led to the prevention of new cases of noise-induced hearing loss and the non increase of the degree of auditive impairment in those cases in which impairment had already been diagnossed despite the significant incease in age and exposure time of the group being studied. At the beginning of the study, 38.5 % of the workers complained of impaired hearing and 23.1 % had extra-auditive symptoms of impaired hearing. An evaluation of the HCP, only 7.7%
had auditive symptoms auditive of hearing loss and the whole group (100%) had no extra-auditive manifestations. |
