Industrial noise levels and annoyance in Egypt
Applied Acoustics, (2011)
Abstract
Annoyance and increase of accident risk of workers from industrial
noise levels in Egypt were studied. 683 workers from 15 Egyptian
sites of industry, ranging from food to metal industry were evaluated.
The goals of this study are to carry out measurements to evaluate
industrial noise levels, are these levels exceeded the permissible
levels set by Egyptian noise standard and policy to protect public
health of workers?, to examine worker’s attitudes towards industrial
noise, to know the relationship between industrial noise levels and
degree of annoyance. Results showed that equivalent continuous noise
levels ranged from 70 to 100 dB (A). Annoyance of respondents showed
that 47.1% were highly annoyed, 5.8% their hearing were harmed. There
was a strong relationship between industrial noise levels and percentage
of highly annoyed respondents. By increasing industrial noise level
possibility of workers to make accident was also increased. Respondents
suggest less maximum daily exposure duration than those set by Egyptian
law.
