background acoustic trauma is an injury to the hearing mechanisms in the inner ear due to excessive noise. this injury is the most prevalent cause of sensorineural hearing loss in humans, especially from occupational exposure. previous studies have shown the essential role of free radical formation in the inner ear hearing loss caused by acoustic trauma. objectives this study was performed to d...

  Background: The sound is an environmental and occupational pollutant and can cause a number of reactions in human body, in which hearing loss is one of the most important effects. Cement industry is one of the industries with noise induced hazards. The aim of this study was to evaluate the noise level in different parts of Kerman Cement Plant.   Materials and Methods: This descri...

noise-induced hearing loss (nihl) is the most common complication of long-term noise exposure, though there  are  some  other  complications  due  to  exposure  to  noise.  metabolic  complications  of  the  noise exposure are being evaluated in recent studies. we aimed to assess the relationship between nihl and lipid profile, and fasting blood sugar (fbs). in this cross-sectional  study, 462 ...

background : noise pollution and workers' noise exposure are common in industrial factories in iran. in order to reduce this noise pollution, evaluation and investigation of noise emission are both necessary. in this study, different noise mapping methodsare used for determining the distribution of noise.   materials and methods : in the present study, for preparing a noise map in a hall o...
