abstract background: previous studies have indicated an unspecific correlation between noise exposure and blood pressure disturbances. blood pressure disturbances could be caused by the environmental hazards such as noise exposure. the aim of this study is to analyze whether there is a relationship between noise exposure and hypertension. methods: atotal sample of 218 workers working in a small...
conclusions the significant difference between groups 1 and 3 permits to establish a correlation between degree of nicotine addiction and hearing loss. however, further studies are needed to identify the mechanisms leading to hearing loss. patients and methods the study recruited smokers (100) and non-smokers as a reference group (100) aged 21 to 50 years living in noisy or quiet areas of beiru...
Hearing loss is a controversial occupational disease in fire fighters because exposure to hazardous levels of noise in this job is so variable and unpredictable. In this study, audiometric assessments were performed on 117 fire fighters to evaluate their hearing loss. The results showed that the average fire fighter has a characteristic noise-induced threshold shift, with maximum hearing loss o...
Objective(s): Noise-induced hearing loss (NIHL) is the major cause of acquired hearing loss. Celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, is a non- steroidal anti- inflammatory drug (NSAID) with known antioxidant and antineoplastic activity. Therefore, we monitored the extent of temporary noise- induced threshold shifts (TTS) and cochlear damage caused by high level 4- kHz noise exposure t...
Noise induced hearing loss in adults is the most cause of sensory neural hearing loss after the presbycusis and industry workers severity affect by degenerative results of that. Three large works of Hamadan city which had more than 200 Workers were selected in this demonstrative quest . The mean of sound pressure leve...
Introduction: Noise is one of the most common and harmful physical factors in the working environment and has physical and psychological effects on individuals.
