Noise-Induced Hearing Loss Among Quarry Workers in a North-Eastern State of Malaysia: A Study on Knowledge, Attitude and Practice

Abstract

The knowledge, attitude and practice scores of the respondents were poor and the high prevalence of noise-induced hearing loss was contributed by factors such as poor practice and old age.

Knowledge, Behaviors and Attitudes about Noise-Induced Hearing Loss among Adults in Albaha Region : A Cross-Sectional Study

“…In general, our study showed low level of knowledge and attitude towards NIHL. Comparable results were reported by other studies (6,11) . Awareness improvement occurs after health educational programs using pamphlets and regular training (13) .…”

“…Military experiences and riding motor cycles represented 13 % each. Different results were reported in other studies, where road traffic was the highest represented source of noise (73 %)followed by music and home noise (26%) in another study (11) . Nearly 15% of the workers said that bloody discharge is one of the signs of NIHL.…”

Prevalence of Hearing Loss and Hearing Impairment among Small and Medium Enterprise Workers in Selangor, Malaysia

“…None of the respondents was experiencing severe or profound hearing condition. These findings showed that most of the study respondents were at early stages of hearing impairment which is similar with study done by Filza Ismail et al (2013).…”

“…Operator, general workers and supervisors normally work more than 40 h per week near noise sources. Thus, it can be assumed that low socioeconomic groups were at greater risk of developing hearing loss, which is similar with findings from Filza Ismail et al (2013).…”

“…However, further analysis need to be done to fully understand about the relationships between them. Prevalence of hearing loss (73.3%) for manufacturing workers in this study was considered high compared to other local studies of different industries such as 57.0% in quarry workers (Filza Ismail et al 2013), vector control workers 26.0% (Masilamani et al 2014). When compared to the hearing loss prevalence of workers in other countries, the prevalence of respondents in this study showed a more severe condition as it was higher.…”
