Teus in action! great work :super:

:ws:

excellent-a-mundo !

small note: maybe change the cfm/db comparison on the first page with a graph or better looking chart

Editor doesn't have the tools / time available to do this right now
but it is added to list for him when he gets home :D

Sorry that i can't agree with you. From what i have learned, decibel is
logarithmic. i think the formula is decibel = 10 log X where X is the ratio of
2 sound.

When you add 20Db to 20Db, you don't get 40Db but 23Db(i am not sure the
correct answer). But I know 20Db is 10 times louder than 10Db and 30Db is 100
times louder than 10Db.

Other than this, I enjoy what you wrote. :-)


regards.

good thinking
anywayz... as I stated: the more CFM, the drastically more noise

can you quote what is yours & what is by Cheong? :)

edit...

that dBA stuff, major mistake :/

yep, you should have known that one TeuS..

Is it possible that in the papst comparison chart the 8412 N has to be 8412 NG?

indeed ;)

I'll correct it as soon as I'm back from eating w/ parents and my network is online :*

1 month later, JMke corrects the error :p
