An assessment of the implementation of the Hearing Conservation Programme: a case study of Farm Workers in Vhembe District, Limpopo Province in South Africa

Ratshilumela, Thinawanga Patricia 18 May 2017 (has links)
MPH / Department of Public Health / Hearing Conservation Programme (HCP) has been reported to be effective in protecting the hearing of South African workers who are exposed to occupational noise. In order to reduce Noise Induced Hearing Loss (NIHL) among these workers, a team work that includes an Occupational Audiologist in the proper implementation of hearing conservation programme is needed. The aim of this study was to assess the implementation of hearing conservation programme amongst farm workers in Vhembe District, Limpopo Province in South Africa.A quantitative research approach using cross sectional survey design was used to assess the implementation of the programme among farm workers in Vhembe District, Limpopo Province in South Africa. A self administered questionnaire with both open and closed ended questions was administered to both males and female respondents aged between 19 and 50 years. A total population of 260 farm workers were systematically selected and a sample size of 76 respondents were randomly selected and participated in the study. Permission to conduct the study was obtained from the Ethics Committee of the University of Venda and the office in charge of royal macadamia. The data collected was analyzed using the Statistical package of Social Sciences (SPSS) version 23,0 software. A test-retest method was used to ensure reliability and findings of the study and formed the basis of recommendations. The results of the study indicate that 82,9% of the workers who were exposed to noise for more than 14hours were not using hearing protection devices even though they were supplied. The training on the effects of noise on hearing was received by a quarter (25%) of the farm workers leaving out a large portion of 75% of workers not knowledgeable about the hearing conservation programme. A very small percentage of 3,9% indicated that they had a documented hearing loss against a large number of 96,1%. The findings show that only engineering noise controls are available and there were no provision of noise maps as part of monitoring hearing conservation programme.The farm workers need to be motivated to wear hearing protection devices in order to conserve their hearing. The management of the farm may organize an in-service training regarding the proper implementation of hearing conservation programme.Dermacation of noise zones would remind workers to put on their ear protectors before entering the noise area as part of monitoring the hearing conservation programme.
