SnowPunk98 writes "OCModShop has done a review on a SilenX 400w 14 dBA PSU "The power supply doesn't boast any flashy designs or cool colors however that is not the purpose of this power supply. Silence is what the main goal of the unit is and there are tons of features to help achieve that.""

There are dozens of "silent" PSUs around. Just bought myself one a couple weeks ago... What exactly makes this review of one a headline?

Offtopic but still...

No, you're not alone. As a matter of fact, I can usually hear if a TV set is turned on in another room, even if the door is shut, or even on another floor (yes, the TV is muted) due to the high-frequency tone it emits.

The noise is generated in all CRT's; TV set, computer monitor, CRT projector, osilloscope, etc and is called the "line frequency". The frequency of the tone is 15.734 kHz, wich is well within the human hearing range.

However, modern equipment generate a lot less - if any - of this noise. The generated sound really is a biproduct of the frequency used to generate the line scan of the electron sweep. I am unable to hear any line noise from my brand new computer monitor but I can hear some (but not a lot) from my old TV set. Some really old TV sets and PC monitors make so much noise that I am unable to stay in the same room as the monitor for any period of time without developing a brain tumor.

Also, many (most?) people over a certain age does in fact NOT hear this sound, due to reduced hearing. Although reduced hearing is in no way something to crave, I wouldnt mind being unable to hear this tone. It can be terribly annoying and distracting and can even cause headache. In fact, many people who have trouble with headaches after a day of office work should try upgrading their monitors. Even if they are unable to conciously HEAR the sound, the ear is still recieving the noise (and the noise melting their brains - or something).

There is, AFAIK, no relationship between ADHD or ADD and being able to hear the line noise. Whether or not you ARE able to hear it would solely depend on your hearing. Bare in mind that you can have certain part of the frequency range reduced or "enhanced" due to various factors. For example, frequent visit to discos and clubs, where loud music is played, is a sure-fire way to remove that line noise from your hearing (although the tinnitus you'll develop can be even more annoying).
