(snip - sorry, busy changing hosting & ISPs re Sven still)
Yes - correct. No, I too don't like the "subjective loudness" For engineers it's a variable constant which they tend not to like :-) It comes from... o Perception of low noise levels is poorly modelled by dB(A) o Perception of the /components/ of low noise levels being poorly modelled by dB(A), yet can be more important than absolute sound pressure level A classic example of the latter is two PWM solutions: 1-2kHz & 10-20kHz, whilst their dB(A) figures may be identical - the perception is not identical. -- Dorothy Bradbury |

Baffie - typed:
It ain't a problem for me as I've got my power settings shutting down the HD after 10 minutes of inactivity, saves power, saves wear and tear and prevents heat/noise. I went down the route of quietening down my PC by purchasing a Zalman Cu Flower Cooler, NB passive HS QPC sound deadening kit & running the exhaust fan at 7V. Most of the noise comes from 2 WD1000JBs. Choosing burners or anything else without tiny fans also helps. I got over-zealous by also having my discs power down after a preset time but noticed an unacceptable stuttering while XP waited for them to spin back up, so disabled it. Going from a steel to Al Lian Li case also helped temps & noise. The 2 inlet fans blow into my 2 h/ds & I have their 3 speed switch set to low. At least WD are now going to introduce h/ds with fluid bearings - about time too! At least my PC is totally silent in Standby mode. |
