Background: Surgeons and anesthesiologists working in orthopedic operating theatres are exposed to significant noise pollution due to the use of powered instruments. This may carry a risk of noise-induced hearing loss. The present study was designed to quantify the noise pollution experienced by anesthesiologists at Imam Khomeini Hospital which is one of the largest Iranian hospitals. Methods:...
Introduction: Occupational noise exposure induced hearing loss is recognized as one of the most harmful factors in industries. Hearing loss is one of the 10 top works–related diseases. This study is to determine the existence of noise pollution in the workplace and probability of its hearing injury among exposed workers in Sarkhoon refinery in 2008, Bandar Abbas, Iran Methods: In this cr...
Introduction: Noise Induced Hearing Loss(NIHL) is among the most common occupational diseases which may cause irreversible and permanent hearing loss. Noise is the most frequent preventable occupational exposure. The most importanmt cause of NIHL is exposure to noise more than 85 dB and not to use hearing protection devices. Considering the importance of hearing protection deivices for preventi...
Abstract Background: Noise-induced hearing loss is among the most common occupational diseases and is completely preventable despite being permanent and irreversible. Although management and engineering control are in prior, for some reasons its implementation is difficult in certain circumstances. So, Hearing Protection Devices (HPDs) are often the only method. But most of workers exposed to ...
Abstract Background : Noise is the most common hazard in the workplace and noise induced hearing loss considered to be the most common occupational disease as well. Cigarette smoking, in some studies, has been known to induce hearing loss. The purpose of this study was to evaluate the effect of contemporary exposure to occupational noise and cigarette smoking on hearing. Methods :...
Background and Aim: Noise induced hearing loss is one of the most common occupational diseases in the world. It is thus introduced as one of the ten principle work-related diseases. According to the estimation of WHO, noise approximately causes a daily loss of 4 million US dollars throughout the world. Materials and Methods: This cross-sectional and analytical study was carried out on 100 worke...
Noise-induced chaos is an interesting phenomenon. However, it is a subtle issue because of the difficulty in distinguishing between true low-dimensional chaos and noise. In this review article, we consider how to define noise-induced chaos and what constitutes a test for noise-induced chaos. The mechanism for noise-induced chaos is studied by considering the long-term growth rate of the logarit...
