INTRODUCTION Hearing loss is one of the most common occupational diseases. In most workplaces, workers are exposed to noise and solvents simultaneously, so the potential risk of hearing loss due to solvents may be attributed to noise. In this study we aimed to assess the effect of exposure to mixed aromatic solvents on hearing in the absence of exposure to hazardous noise. MATERIALS AND METHO...

BACKGROUND Twenty-two million workers are exposed to hazardous noise in the United States. The purpose of this study is to estimate the prevalence of hearing loss among U.S. industries. METHODS We examined 2000-2008 audiograms for male and female workers ages 18-65, who had higher occupational noise exposures than the general population. Prevalence and adjusted prevalence ratios (PRs) for hea...

introduction: serum anti endothelial cell antibodies (aecas) play a prominent role in idiopathic sensorineural hearing loss (snhl) in that they induce vascular damage (immune mediated).the of the current study is  to compare aecas in serum and perilymphatic .uid of idiopathic snhl children (<15y) undergoing cochlear implant surgery.methods: this was a cross sectional study performed in the coch...

UNLABELLED Teachers frequently report auditory symptoms and excessive noise in classrooms, but noise level measurements are not done routinely. Study model - a prospective clinical trial. AIM To study auditory symptoms and audiometric exams of teachers and classroom noise levels. MATERIAL AND METHOD Data from two groups, GI (40 teachers) and GII (40 voluntaries) were studied as follows: age...

OBJECTIVES Ototoxic effect of exposure to lead has been reported by many researchers. This study was undertaken with a view to investigate the relationship between blood lead level (BLL) and hearing loss in workers in a lead-acid battery manufacturing plant in Tehran, Iran. METHODS In a cross-sectional study, 609 male workers were recruited from different locations in the factory. Association...

BACKGROUND An association has previously been reported between finger blanching and hearing difficulties, but only in workers with exposure to noise and hand transmitted vibration (HTV). AIMS To explore the association in a community sample, including cases who lacked occupational exposure to noise or HTV. METHOD A questionnaire was mailed to 12 606 subjects aged 35-64 years, chosen at rand...

BACKGROUND Noise is the most common occupational hazard. Noise-induced hearing loss (NIHL) is a known occupational disease. The economic costs of NIHL have been estimated to be billions of dollars. Besides, cigarette smoking is a common habit worldwide. METHODS In a cross-sectional study, we surveyed the effect of smoking on NIHL in 504 workers in a large wagon manufacturing company exposed t...

Occupational noise-induced hearing loss remains a common problem in industry. This report presents a systematic method of patient evaluation and describes software that is capable of calculating hearing handicaps from audiometric data and the proportion of the handicap due to presbyacusis. The software also has the capability of subtracting the effects of presbyacusis from the current audiometr...

Analogue to occupational noise-induced hearing loss, MP3-induced hearing loss may be evolving into a significant social and public health problem. To inform prevention strategies and interventions, this study investigated correlates of adolescents' risky MP3-player listening behavior primarily informed by protection motivation theory. We invited 1687 adolescents (12- to 19-year old) of Dutch se...
