im just trying to get an idea of how loud 30dBa really is?

thanx

Usuallyanything under 30Db is quiet. The smaller the fan could make more Db level than a larger one. Getting a true reading from the manufactor is also difficult.

Something about 20 dBa is quiet. 30 too much. It's not very noisy but you can hear it well enough.

WOW thanx. the link was great.

Myself, I would be interested in the noise level while attached to the desired equipment.

I have a radioshack fan that is something like 65 or 85 CFM @ 12 volts.

oh it's pretty quiet pushing open air, but even when it's down to 7volts it's just about the loudest part on my machine.

I gotta get new fans dangit

Let me go get my Physics book

well here we go :
(all values are in dB)

140 - jet aircraft taking off at 30m
120 - disco loudspeaker at 2m
100 - pneumatic road drill at 4m
90 - Heavy lorry passing at 4m
80 - door slamming at 2m
70 - vacuum cleaner at 2m
60 - normal conversation
40 - background noise at home
20 - whisper
0 - threshold of hearing sound just audible
