BACKGROUND AND OBJECTIVES The hearing loss of workers can occur when they are affected by age, otologic disease, and work-related risks such as noise and chemicals. Based on the Korean Working Conditions Survey (KWCS) in 2010, this research aimed to estimate the prevalence rate of hearing loss and to identify the risk factors affecting its occurrence. SUBJECTS AND METHODS The subjects were 10...

UNLABELLED INTRODUCTION Tinnitus is considered the third worst symptom affecting humans. The aim of this article is to assess complaints by workers with tinnitus exposed to environmental and occupational noise. METHODOLOGY 495 workers went through an epidemiological survey at the Audiology Department of the Center for Studies on Workers' Health and Human Ecology, from 2003 to 2007. The wor...

background: traffic noise is one of the major sources of environmental pollution that can cause permanent or temporary loss of hearing in drivers. the purpose of this study was to estimate the prevalence of hearing loss among professional long-distance drivers in bandar abbas freight terminal. methods: one thousand long distance occupational drivers in bandar abbas freight terminal not certifie...

BACKGROUND Noise exposure is the most frequent occupational factor which may increase the risk of work-related injuries. The purpose of this study was to estimate the association between occupational injuries and noise exposure as well as hearing loss. METHODS This study was conducted from April 2008 to March 2009 on 1062 workers in the Tabriz Tractor Manufacturing Plant. Sound pressure level...

Background Manufacturing sector accounts for 18.1% of the total employed persons in Malaysia, which is known for the utilisation of noisy machinery to establish output. Even though it is compulsory for employers to notify any hearing loss cases to the authority annually, there is still scarcity of occupational hearing loss cases. Therefore, this study aimed to estimate the total number of worke...

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 Met...

The aim was to study hearing loss in a population of aircraft technicians and mechanics and indentify predictors. Equivalent noise levels during a working day were measured and were 70-91 dB (A). Maximal noise level was 119 dB(A). A total of 336 aircraft maintenance personnel answered a self-administered work environment questionnaire (response rate 76%) and underwent audiometric test. The mean...

AIMS To survey current, Danish industrial noise levels and the use of hearing protection devices (HPD) over a 10-year period and to characterise the association between occupational noise and hearing threshold shift in the same period. Furthermore, the risk of hearing loss among the baseline and the follow-up populations according to first year of occupational noise exposure is evaluated. MAT...
