Noise control enclose equipment

Actually, there are many sources of annoyance noise in computer operations. Fans in computers, printers, and other accessories, which are used to maintain a favorable internal device temperature, are a source of noise. Office ventQation fans can also be a source of annoyance noise. The computers themselves may be a source of noise (e.g., the cUck of keys or the high-pitched squeal of the CRT). The peripheral equipment associated with computers, such as printers, can be a source of noise. Problems of noise may be exacerbated in open-plan offices, in which noise is harder for the individual employee to control than in enclosed offices. 

Look for noisy locations in a floor plan or plant layout. Look for ways to enclose potentially noisy activities, processes, and equipment to prevent noise from traveling to less noisy areas. Group noise sources to lower costs for controls. Try to separate people from noise sources by distance and barriers. Look for and avoid routes or channels by which sound can travel from one location to another. 

Isolation of workers in acoustically-quiet booths or control areas properly enclosed, coupled with scheduling of work periods to reduce dose. This will only be effective where there is little or no need for constant movement into or out of areas with high noise levels even a short duration exposure to high sound pressure levels will exceed the permitted daily dose. Nevertheless, improved design of vehicle and plant cabs and (for example) batch plant and lifting equipment operating positions can do much to improve the health of operators.
