BACKGROUND Evidence has accumulated concerning the adverse effects of smoking on hearing acuity, but it is not clear whether smoking modifies the association between exposure to noise and hearing loss. AIMS To examine the synergistic effect of these variables on hearing. METHODS Data used were derived from periodic health examinations for 4624 steel company workers in Japan and included aud...

BACKGROUND This study examined hearing loss prevalence and hearing aid usage rates among Korean elders by comparing the differences between those with and without hearing loss, and between those who used and did not use hearing aids. METHODS This study was based on data collected during the Korean National Health and Nutrition Examination Survey V (2010-2012). The study sample consisted of 5,...

Noise is a major occupational and environmental hazard, causing hearing loss, annoyance, sleep disturbance, fatigue, and hypertension. Although the extra-auditory effects of high-level noise exposure have been reported, noise-induced hearing loss (NIHL) has long been recognized as the primary and most direct health effect of excessive noise exposure. The World Health Organization reported that ...

The article presents a preliminary evaluation of occupational hearing loss risk in a group of farmers selected at random and exposed to a mean annual level of exposure to noise L(EX,8h) = 89.1 dB. The study covered 31 family farms carrying out mixed production (plant-animal), possessing arable land of the size 5-40 ha, and equipped with the basic mechanical equipment (tractors, agricultural mac...

conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...

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...

OBJECTIVE To determine the prevalence of hearing loss associated with occupational noise exposure and other risk factors. DESIGN A cross-sectional study involving 269 exposed and 99 non-exposed subjects (non-industrial noise exposed subjects) randomly selected. Current noise exposure was estimated using both sound level meter and noise-dosimeter. Past noise exposure was estimated by interview...

BACKGROUND Smoking has been shown to have adverse effects on hearing, but it's unclear whether smoking interacts with known causes of hearing loss such as noise exposure and ageing. AIMS To examine the hypothesis that smoking, noise and age jointly affect hearing acuity. METHODS This cross-sectional study was carried out in 535 male adult workers of a metal processing factory. Pure-tone aud...

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...
