“…26 Accordingly, Fernandez et al suggested procedures to reduce measurement uncertainty, including the simultaneous use of dosimeters and sound level meters, the correct selection of the measurement period, and workers' observation during measurements. 27 In this study, environmental noise exposure was measured using a sound analyzer (TES-1358; TES Electronic Corp., Taipei, Taiwan) that measures 1-second to 24-hour continuous equivalent sound levels (Leq) in the range of 30-130 dBA as well as timeweighted-average noise levels. This equipment was calibrated with a sound-level calibrator (TES-1356; TES Electronic Corp.) before environmental monitoring.…”

Background: The gene-environment interaction in the pathogenesis of hypertension has not been extensively studied in occupational noise. Objectives: The aim of this study was to determine the relationship between noise and hypertension in Egyptian workers, the interaction of angiotensin-converting enzyme (ACE) gene polymorphisms as modifiers, and the possible relationship between noise hearing impairment and hypertension. Methods: Study subjects were divided into two groups depending on noise exposure level. The control group (n5161) was exposed to noise intensity ,85 dB and the exposed group (n5217) was exposed to noise intensity §85 dB. A polymerase chain reaction was used to differentiate the various genotypes of ACE insertion/deletion (I/D) and ACE G2350A. Results: Noise significantly increased the likelihood of hypertension. Carriers of the genotypes AG, GG, and DD were vulnerable to hypertension on noise exposure. No association between hypertension and hearing impairment or noise-induced hearing loss (NIHL) was found. Conclusion: Our results support the association between ACE gene polymorphisms and occurrence of hypertension in noise-exposed workers.

“…Prolonged periods of noise exposure cause deterioration of mental and physical capacity, emotional instability, irritability, decreased ability to concentrate, impaired reaction time and reaction quality, and premature fatigue (Mohammadi 2008;Hnilica et al 2013). Noise is the most frequent source of work related accidents and occupational diseases (Fernández et al 2009). Hearing loss is seldom immediate (this can be caused by noise of more than 130 dB) but it can cause either temporary or permanent hearing threshold shift (Melnick 1991).…”

This article was aimed at assessment of selected factors of the work environment, which influenced the operators of harvesters and forwarders. The selection of the work environment factors was based on a thorough literature survey. From the survey exposure to whole-body vibrations, noise (equivalent and peak), microclimatic conditions and mental load were selected for detailed observations. The measurements were conducted according to international standards and assessed according to European or national legislation. Subjective assessment of the effects of the work environment was conducted through a structured interview. The exposure to whole-body vibrations was 0.5 m·s -2 . The equivalent noise exposure was 78 dB, peak noise exposure was 130 dB. The average temperature inside the machine cabs was 17.9°C and average airflow velocity was 0.06 m·s -2 . Mental load was high according to the Meister questionnaire, three operators considered the load inadequate, two considered it adequate. Subjective assessment showed that operators considered other factors to be light or no load.Keywords: noise exposure; whole-body vibrations; microclimate; mental load Work environment is a set of all conditions in which workers carry out their work. It consists of all workers and factors present at the workplace, or of those who have to do with the work and influence the health or comfort of workers. The worker is exposed to many harmful factors which interact and their joint effect can be synergistic or complementary (Schwartz et al. 2013).Operators of multi-operational machinery carry out their tasks in ergonomically designed cabs capable of partial attenuation of noise and vibrations caused by the machine movement, driving gear, and working parts of the machine. Cabs are also equipped with air conditioning and glare reducing windows. Some factors (e.g. electromagnetic, ionising radiation, various chemical factors, or energy expenditure) do not apply to the jobs of multioperational machinery operators. Their assessment would only consume time with no significant effect on the overall outcome of the assessment. The nature of work in mechanized logging partially shifted from physical to mental after employment of multi-operational machinery. The need for muscular activity decreased and the need to stay concentrated and alert through long periods grew in importance. Harvester operators have to be able to process a lot of information, react quickly, and retain their concentration in monotonous, repetitive operations (Axelsson, Pontén 1990;Poschen 1993;Gellerstedt 1997;Gellestedt et al. 1999;Tsioras 2012). Operating the machines is quite demanding. According to Gellerstedt (2002), 4,000 control inputs per hour have to be carried out by the operator, due to the lack of automatic functions of the boom and harvester head. Despite the ergonomic design of the cabs, the operators of mobile machinery are exposed mainly to noise (Hans-

“…Especially in the developed countries, where the models of social and economical organization, the technological development and the growth of population are key factors in the increase of noise pollution (Fernández et al 2009). Noise is one of the most important acoustic pollutants in the nowadays society, as it is present in most of people's activities; consequently, not only the workers of certain sectors but also all the citizens are exposed to high-noise doses (Ballesteros et al 2010).…”

The levels of noise arise from mining industry seem to be higher when compared to other industries. For this reason, noise exposure and noise-induced hearing loss (NIHL) are prevalent in mining. Assessment of noise emission levels that arise from various mining operations is required to prevent and minimize the NIHL. Because the studies for preventing occupational hearing loss among miners are inadequate, a quarry and stone crushing-screening plant was selected to generate site-specific data. The noise levels of the environments in which workers work were measured and also a hearing test centre applied hearing tests to the workers. According to the hearing test results, it was determined that the part of workers have hearing loss. The main factors affecting the NIHL were assumed as experience, noise level, miners' age and occupation, and by taking into account the sub factors of the main factors, multi way contingency tables were prepared. Then hierarchical loglinear analysis method was implemented to categorized data; thus, the probabilities might effect NIHL was investigated. At the end of this study, it was found that the most risky occupation group was the drivers, and additionally, these workers were mostly exposed to 70-79 dB(A) noise level. When the important interactions are evaluated, it is determined that 4-11 years experienced crusher workers have high probability of NIHL because of high exposure to 90-99 dB(A) noise level. Moreover, the most important interactions which may affect the NIHL were identified and the precautions to reduce hearing loss were presented.
