Noise annoyance is a strong measurable mental response. It is a reaction that a person expresses to the noise exposure. Thus, this study investigates the correlation between noise exposure and its annoyance in terms of mental health components. </span></span></span></span></div> <div style="text-align: justify;"><span style="font-family:Arial;"><span style="font-size:12px;"><span style="line-height:250%"><span style="color:black"><b>Materials and Methods:</b> This was a correlational descriptive study conducted on 100 workers. Respondents were recruited by a simple random sampling method. The equivalent sound level (LeqA) was determined using dosimetry. The numerical scale of ISO/TS 15666:2003 was used to measure noise annoyance. Mental health components were determined using the SCL-90 mental health questionnaire. Data analysis was performed in SPSS software (version 22) using Mann-Whitney, Kruskal&ndash;Wallis, and correlation tests.</span></span></span></span></div> <div style="text-align: justify;"><span style="font-family:Arial;"><span style="font-size:12px;"><span style="line-height:250%"><span style="color:black"><b>Results:</b> The median of mental health and noise annoyance were 38 and 6.5, respectively. A positive correlation was observed between equivalent sound level (LeqA) and noise annoyance score (P<0.001, r=0.92). A significant correlation was found between mental health components (depression, anxiety, self-morbidity, obsession and compulsion, aggression, morbid fear, paranoid thoughts, psychosis, and sensitivity in interpersonal relationships) and equivalent sound level (P<0.001). Also, a significant correlation was observed between noise annoyance score and mental health components (P<0.001).</span></span></span></span></div> <div style="text-align: justify;"><span style="font-family:Arial;"><span style="font-size:12px;"><span style="line-height:250%"><span style="color:black"><b>Conclusion:</b> We concluded thatin order to enhance the mental health of employees and increment efficiency and performance, it is recommended that appropriate control methods should be applied. </span></span></span></span></div> Noise-Induced,Hearing Protective Device,Mental Health,Depression,Anxiety,Industry,Aggression,Psychotic Disorders, 148 156 http://johe.rums.ac.ir/browse.php?a_code=A-10-457-1&slc_lang=en&sid=1 Rohollah Fallah Madvari fallah134@gmail.com 22400319475328460011312 22400319475328460011312 No Assistant Prof., Occupational Health Research Center, Dept. of Occupational Health Engineering, School of Public Health, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.
