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...
the aim of the present study was to examine the rate of noise induced hearing loss in a group of punching and cutting section and other occupational groups workers and its relation with sound pressure levels, age and work history. this descriptive, cross-sectional study included 245 workers of the punching and cutting section and other occupational groups of an iranian axial parts factory in 20...
We study the origin of the Noise-Induced Hearing Losses (NIHL) in relation to the morphology and the physiology of the ear. We describe the mechanical and metabolic effects of the noises on the inner ear and their consequences on hearing. We discuss the importance and the limitations of the protective mechanisms. Finally, we present new possibilities to protect the ear against noise and to trea...
OBJECTIVE To investigate whether single nucleotide polymorphisms (SNPs) in the Mn-superoxide dismutase gene (SOD2) underlie the susceptibility to noise-induced hearing loss (NIHL). METHODS Audiometric data from 2400 Chinese Han workers who exposed to occupational noise were analyzed. DNA samples were collected from the 10% most susceptible and the 10% most resistant individuals, and five SNPs...
