The art of reducing your computer's noise

Computer noise may not hurt your hearing but it may add to your stress ...

"Increasingly powerful PCs mean a greater need for cooling, but reducing the racket seems not to be a priority for manufacturers

...Nonetheless, computer noise is becoming a mainstream issue, especially since people are beginning to build media centre PCs into their home audio/video systems. And who wants to watch a great movie or listen to a fine piece of classical music over a high-pitched whine in the wrong key?

... Why not just ignore it? How well you can filter out noise depends on a number of factors, such as the sensitivity of your ears, the intensity and frequency of the noise, and how persistent it is. "The human auditory system adapts quite quickly," says Tom Stewart, founder and director of the ergonomics consultancy System Concepts. "So we tend not to be aware of how noisy an environment is [until equipment is switched off]. But the noise can contribute to our overall stress levels and tends to make us tense generally."

However, he says, hearing damage in modern offices is "unlikely". This is especially so since the Noise at Work Regulations came into force last year for most sectors. These set the level above which employers must take action at 80db - about the noise level of a tractor cab or very loud music. "Most offices are closer to 40db to 55db."    (Continued via Guardian Unlimited)    [Ergonomics Resources]
