background: noise-induced hearing loss (nihl) is a common, irreversible occupational disease. statins have recently been proposed to prevent nihl. objective: to assess the effect of atorvastatin for the prevention of nihl in rats. methods: in this experimental study, forty 2–3-month-old wistar male rats were divided into 5 groups of 8 animals. 3 groups of rats received atorvastatin at doses of ...

results the mean age and work experience of workers were 31.39 ± 5.6 and 4.35 ± 2.5 years, respectively. among the exposed-to-noise personnel, 7.35% used hpds constantly; 75% used hpds for only short periods of time (less than four hours) and 17.65% did not make use of them at all. regarding the sound intensity and the level of noise reduction of hpds, among the 112 workers who used such device...

background: noise can cause permanent or temporary hearing loss. high levels of noise may stimulate the vestibular system and thereby cause disturbances in the balancing mechanism. objective: to determine the effect of long-term exposure to occupational noise on the vestibular system. methods: a dizziness questionnaire was administered to 20 factory workers who were exposed to occupational nois...

background: this paper describes the common hazards in the metal industry – chemicals and noise. the aim of the study was to get an overview of risk levels of mentioned occupational hazards and examine the implementation of adequate safety measures. methods: measurements of noise and chemicals were performed, self-reported exposure and usage of personal protective equipment from workers were us...

background: in the steel industry, coke-fueled furnaces are used for smelting iron ore to produce cast iron are considered as sources of annoying noise.this study aims to evaluate the noise pollution blast furnace and sound source characteristics in order to present noise control measures in the steel industry. methods: measurement of noise level and its frequency analysis was performed using s...

background: noise-induced hearing loss (nihl) is one of the most common occupational illnesses. most of the studies on nihl were conducted at high noise levels that people are rarely exposed to but in industries. the function of the outer hair cells (ohcs) is impaired after exposure to industrial noise. distortion product otoacoustic emissions (dpoaes) are useful in examination of noise-induced...
