“…A major risk in life is an occupational hazard, which typically arises as a result of exposure to specific harmful agents at the workplace ( 1 ). Workers in different industrial environments are constantly exposed to many environmental agents such as heat, vibration, cold, humidity, lighting, noise, etc., which are considered as the greatest threats to productivity and efficiency of workplaces and can affect the health, comfort, and performance of workers ( 2 ).…”

IntroductionOccupational noise is among the most critical occupational hazards, which, in addition to hearing loss, can cause other adverse consequences on an individual’s physical and mental health. Long-term exposure to noise can affect blood and biochemical parameters and subsequently lead to increased risk of cardiovascular disease. This study investigated the effect of occupational exposure to noise on blood and biochemical parameters of workers in an insulator manufacturing plant.MethodsThis case-control study was conducted on workers in the production section (49 people as a case group) and the administrative staff (10 people as a control group) in one insulator manufacturing plant from 2010 to 2014. To assess individual exposure of workers to noise, the noise dosimeter model TES-1355 was used. Noise dosimetry testing was done based on the exposure pattern of workers to noise in compliance with the Iranian national standard (the criterion level of 85 dBA and the exchange rate of Q = 3 dBA). Blood parameters such as blood glucose, cholesterol, red blood cells (RBC), white blood cells (WBC), hemoglobin (Hb), and hematocrit (Hct) were studied in production workers (case) and administrative staff (control) over five consecutive years. The data were analyzed by software (SPSS-22) using the t-test, Mann-Whitney test, Fisher exact test, and Greenhouse-Geisser test.ResultsNo significant difference was found among the demographic data of the two groups (p > 0.05). Average of glucose and cholesterol levels in the two groups was statistically significant (p < 0.05) and blood glucose levels in the case group significantly reduced over time and cholesterol increased (p < 0.001). Mean difference of RBC number, WBC number, and serum levels of Hb and Hct was statistically significant between the two groups (p < 0.05). In addition, these hematological parameters increased among workers during these years.ConclusionOccupational exposure to noise may have a significant effect on an individual’s blood parameters, which will cause harmful effects on worker health. Therefore, industrialists must take preventive measures in the field of noise control.

“…It is estimated that about 600 million workers worldwide have been exposed to noise [ 4 ]. Many studies reported that exposure to noise levels above 80 dB- A in industrial settings is quite widespread [ 5-7 ]. Earlier, most studies focused on noise in office environments and its psychological effects, such as job satisfaction, and less studies have been done on the chronic exposure to noise in industrial environments such as manufacturing sites and etc.…”

“…Every day, in many workplaces, workers are exposed to various harmful agents such as noise, vibration, stress, etc., which may have negative effects on their health safety and performance (1)(2)(3)(4). Noise is considered as the most common and one of the most harmful agents of working environments worldwide (5,6).…”

“…However, it is preventable through avoiding excessive exposure to noise and proper use of personal protective equipment such as HPDs (18)(19)(20)(21). Studies have found that the prevention of hearing damage through the use of Hearing Protective Devices (HPDs) in the industry is low, varying from 20% usage in some studies (3) to 30% -50% in others (22)(23)(24). Although hearing protection devices are Copyright seem to be a temporary solution, due to some economics and applicability aspects, they are widely used as the only measure against noise exposure (25).…”
