Introduction: Occupational hearing loss due to noise is completely preventable and using the hearing protection device is one of control proceedings by the workers expose the impermissible noise. Therefore, this study aimed to determine the effective factors on occupational hearing loss and also the effective factors on using hearing protective devices by the workers exposed to excessive noise....
Introduction: Working in noisy environments may cause hearing loss. Studies have shown that some factors along with noise are independently involved in hearing loss, one of which is cigarette smoking. The aim of this study was to evaluate the effects of smoking on hearing loss in workers exposed to occupational noise. Materials and Methods: The workers’ hearing loss was measured through a tona...
UNLABELLED Exposure to occupational noise may cause injuries to the inner ear, and the distortion product otoacoustic emissions (DPOAE) may identify initial auditory alterations, thus assisting NIHL early diagnosis. AIM The goal of this study was to evaluate DPOAE as a method to diagnose early physiopathological alterations caused by occupational noise exposure. STUDY DESIGN Transversal. ...
OBJECTIVE To develop a job-exposure matrix (JEM) for occupational noise in Sweden and to estimate its validity. METHODS The JEM, developed by a group of experienced occupational hygienists, contains 321 job families with information regarding occupational noise from 1970 to 2004. The occupational noise information derives from measurements collected from different sources. The time period lab...

Background and Aim: Occupational exposure to noise in the workplaces is a significant health problem and cardiovascular disease is one of the most important and common non-communicable diseases and one of the main causes of premature death. In addition to hearing impairments, noise as a stressor may cause cardiovascular problems, high blood pressure, nerve stimulation, stress and hormonal dis...
BACKGROUND Hypertension is the primary out-auditory adverse outcome caused due to occupational noise exposure. This study investigated the associations of noise exposure in an occupational setting with blood pressure and risk of hypertension. METHODS A total of 1,390 occupational noise-exposed workers and 1399 frequency matched non-noise-exposed subjects were recruited from a cross-sectional ...
Introduction: Occupational exposure to excessive noise is commonly encountered in a large number of industries in Iran. This study evaluated the hearing threshold and hearing loss in Meybod tile factory workers. Methods: This cross-sectional study included 371 tile factoryworkers during summer and autumn of 2005. Current noise exposure was estimated using sound level meter .A specially formatt...
For the past few years, noise pollution has been more and more serious, and it may lead to several diseases. While the humans expose to noise in quantity for a long time, their blood pressure will change, and even cause changes in cardiac function. In our study, we attempt to find the relationship between occupational noise and hypertension and impaired hearing, cardiac function. It may be help...
