For mixtures containing organic solvents such as toluene, styrene or xylene, the combined exposure with noise increases the risk of occupational hearing loss in a synergistic manner. [5] [50] The risk is greatest when the co-exposure is with impulse noise. [51] [52] Carbon monoxide has been shown to increase the severity of the hearing loss ...
Overall, audiometric records show that about 33% of working-age adults with a history of occupational noise exposure have evidence of noise-induced hearing damage, and 16% of noise-exposed workers have material hearing impairment. [9] In the service sector the prevalence of hearing loss was 17% compared to 16% for all industries combined. [10]
Occupational noise is the amount of acoustic energy received by an employee's auditory system when they are working in the industry. Occupational noise, or industrial noise, is often a term used in occupational safety and health, as sustained exposure can cause permanent hearing damage.
Occupational noise exposure is the main risk factor for work-related hearing loss. One study examined hearing test results obtained between 2000 and 2008 for workers ages 18–65 who had a higher occupational noise exposure than the average worker. [153] Of the sample taken, 18% of the workers had hearing loss.
Noise exposure is the cause of approximately half of all cases of hearing loss, causing some degree of problems in 5% of the population globally. [5] The National Institute for Occupational Safety and Health (NIOSH) recognizes that the majority of hearing loss is not due to age, but due to noise exposure. By correcting for age in assessing ...
Noise and ageing are the primary causes of presbycusis, or age-related hearing loss, the most common kind of hearing loss in industrial society. [10] [citation needed] The dangers of environmental and occupational noise exposure are widely recognized. Numerous national and international organizations have established standards for safe levels ...
Hearing conservation programs [1] are programs that should reduce the risk of hearing loss due to hazardous noise exposure, if implemented correctly and with high quality. . Hearing conservation programs require knowledge about risk factors such as noise and ototoxicity, hearing, hearing loss, protective measures to prevent hearing loss at home, in school, at work, in the military and, and at ...
Long-term exposure to noise and some medical conditions can also play a role. In addition, new research suggests that certain genes make some people more susceptible to hearing loss as they age. [10] Other risk factors include preexisting noise-induced hearing loss and exposure to ototoxic medications. [11]
