Just measured the noise from my 2010 3.2 GHz (5770) MP.
Front grill top: dBA 44.5, dBC 54
Front grill middle/bottom: dBA 46, dBC 56
Sound level at ear level with MP under the desk:
dBa 40
dBc 50
I'm using an American Recorder SPL-8810 sound level meter.
Qualitatively, I'd call the sound level as quiet with a mid/low frequency tone. This is in a smallish room. In a larger room (office/work) I might not even hear the slight hum of the MP.
For sound/music editors a little bit of sound foam might be useful.
cheers
