Noise induce hearing loss

While a clear causitive role has been established for PMCA2 in hearing loss, further studies on hypomorphic alleles could address their effect on age-related or noise-induced hearing loss. Generating a mouse model of the human V586M mutation should provide an even less affected hypomorph for further studies.

Damage to hearing caused by one very loud event, as in the case of an SRV, may however be different in onset and character to the observed noise-induced hearing loss from lower but more continuous levels. In this situation, damage to the inner ear is caused to the whole organ rather than to certain cells. 

Noise-induced hearing loss is a problem of epidemic proportion in modern society, and is currently the second most common form of hearing impairment in the United States (after age-related hearing loss). Although it is difficult to accurately assess the extent of the problem, the US Centers for Disease Control and Prevention has estimated that 12.5% of US children aged 6-19 years have some form of noise-induced hearing loss in one or both ears, and a 1990 Consensus Statement issued by the US National Institutes of Health estimated that over one-third of the 28 million people in the United States suffering from...

There have also been significant reductions in the number of cases of work-related allergy and noise-induced hearing loss.

G. Occupational ototoxicity is common but is usually noise induced rather than chemical related. Preexisting noise-induced hearing loss may magnify the impact of common ototoxic drugs.

The modern industrial worksite can be a noisy place. This poses two safety and health related problems. First, there is the problem of distraction. Any operation that requires oral communication will suffer from a noisy environment. Interference with communications can create misunderstandings about information transmitted from one person to another. When such communications relate to hazardous activities, any misunderstandings can lead to accidents. Second, there is the problem of hearing loss. Exposure to noise that exceeds prescribed levels can result in permanent hearing loss. Occupational exposure to loud sounds is the most common cause of what is often called noise-induced hearing loss. 

T/F) Occupational noise-induced hearing loss occurs over a period of several years. 

Use of hearing protection in both occupational and non-occupational environments is intended to help reduce noise exposure levels and noise-induced hearing loss (NIHL). In the absence of feasible engineering and administrative noise reduction control methods, use of earplugs or earmuffs is common practice. Unfortunately there are still many myths surrounding the use and effectiveness of hearing protection devices (HPDs). In this article, some of the more common myths and the realities are addressed.

Occupational illness may involve skin diseases or disorders caused by work exposure to chemicals, plants or other substances. They may be respiratory conditions associated with breathing hazardous biological agents, chemicals, dust, gases, vqjors, or fumes at work. They may also be poisonings, noise-induced hearing loss, or other occupational illnesses. 

There are many effects of noise on people. Most effects are detrimental. The best-known effect of noise is noise-induced hearing loss. There are many other effects that contribute to accidents and health problems. 

Many famous musicians have noise-induced hearing loss from a long history of noise exposure. Two with hearing loss are Ozzy Osborne (Black Sabbath) and Pete Townshend (The Who). 

The greatest safety concern is noise-induced hearing loss. Exposure to noise can produce hearing loss. Both duration of exposure and sound intensity can lead to hearing loss. High frequency noise is more damaging than low frequency noise. Continual noise is more damaging than intermittent noise.
