The Cause of Internet and TV Addiction?
'Muffled Computing' offers fan mufflers for power supply, auxiliary, and front computer fans.
· The power supply and auxiliary fans may not fit on all computers.
· Templates are available which you can print out, and use to determine if the muffler will fit on your computer.
· "The power supply muffler significantly reduces noise, but not all noise.
· If you have a noisy heatsink fan, the muffler may absorb some of its sound, but most likely not enough to make a difference.
· The muffler works very well on a direct sound source, but an un-muffled heatsink fan will still be loud.
· If the loudest sound on your PC is the power supply's exhaust fan, this muffler can help."
"Pros: Keeps background noise out; comfortable
long term; double duty noise-cancelling.
"A headset has recently been developed which cancels out very low-level frequency noise. It works well at canceling out the low-level frequency noise generated from the fan on the hard drive of a computer and reducing the whine of a jet engine when traveling on an airplane. I mention these two applications, because these are some of the few ways this new headset helps us in areas that are difficult for us [people with collapsed tolerance to sound] to tolerate over a prolonged period of time. This electronic headset is battery operated and is called the QZ2000 (costs about $200). You can obtain this headset direct from the manufacturer by calling Koss Electronics at 1-800-872-5677 and ask for Consumer Sales.
Many people buy this unit thinking it will cancel out all sounds like people's voices or music - wrong. Noise cancellation appliances at the present time are only canceling out low frequency noise. They are reluctant to manufacture headsets which cancel out high frequency sounds because many high frequency sounds include things like sirens, alarms, and other signaling warning sounds that protect people from danger. Other areas that the QZ2000 headset helps is reducing the sound of leaf blowers, lawn mowers, circulation fans, and ventilation noise. Low frequency noise like this is relatively easy to cancel out."
"Remember that the whine of the fan to cool the hard drive on a computer is soft, but high pitched. Fortunately, the QZ2000 noise cancellation headset or foam earplugs can help you with that. If you get to choose a new computer, the network can give you some recommendations on quiet computers."
Some Practical Solutions
Some people prefer simple solutions which don't involve upgrading computer hardware such as:
· Buying a quieter computer
· Moving your computer behind a wall
· Storing your desktop computer in a desk drawer, and closing the drawer
Low Frequency Noise
Your computer may seem quiet now but, over time, quiet sounds may become irritating, and make it difficult to separate interesting sounds from a background of irrelevant noise (the cocktail party effect).
I've found that playing relaxing sounds at barely audible levels (e.g. pink noise) in one of my ears is helpful.
Upgrading Computer Hardware
"Silent computers are better than noisy computers, provided you go about obtaining one with a little research, planning, and then carefully deploying the silencing methods you have decided on. If you inadvertently create a machine that overheats in your quest for silence you will not be a happy camper due to crashes or even component failure and possible destruction. Noise is not only a distraction, but it is literally unhealthy to work or even play around. It is my intention to help you figure out the sources of noise generated by your PC and then to develop a strategy to safely eliminate as many of them as practical for your individual hardware configuration. If you are planning on building or buying a new PC, this article intended to help you plan for a better, happier, and more productive future through silence."

Antec: 'PC Noise Killer' Kit
"Without having a dB meter it is hard to show if there was any drop in noise. I'll be honest, I couldn't tell any difference after the kit was installed. While this kit isn't going to completely silence your PC it will certainly help out.
Installation is easy enough, and the idea is a good one. I think that having a 60mm size silicone gasket would have been a nice addition as well as a longer rectangle sheet. The longer sheet could be placed under the power supply in a desktop or HTPC [home theater personal computer] case to prevent the power supply from vibrating. Maybe I was expecting more from this kit but with such slow running fans in my HTPC case maybe vibration wasn't as much of an issue.
