Allright, sounds good, Im pretty busy recently with other things,

So, you have reserve on the first one, ish, if you like them

Also, it will be LOUD

L-O-U-D

Just a warning
 
65db x 4 is about 69db not 80 (ap psychics pssh) the pattern is logrithmic, but yea im gonna get some of those delta's
 
well 80dB was keeping it safe. I didn't reallly feel like reaching into my back pack and doing the math : )
 
250 Inside of tornado; conventional or nuclear bomb explosion at 5 m.
180 Rocket engine at 30 m; blue whale humming at 1 m;
Krakatoa explosion at 100 miles (160 km)[1]
150 Jet engine at 30 m
140 Rifle being fired at 1 m
130 Threshold of pain; train horn at 10 m
120 Rock concert; jet aircraft taking off at 100 m
110 Accelerating motorcycle at 5 m; chainsaw at 1 m
100 Jackhammer at 2 m; inside disco

Ah wikipedia, you save me again

So Im heading to vacuum range, nice =)

*keeps adding fans till I make it 250dBs*

Lawl

Id be happy with a jet sound
 
I think the increase in sound would become very minimal for each fan. So you would probaly need about a billion fans to reach the sound of a jet lol.
 
Lawl. Yeah I know, but Im just imaginin

Yeah, imaginin is a word.. to me

So does anyone like my design for it?

And would anyone buy it for $450-$500?
 
idk but i could figure it out though! hmmm...lets see..
1 @ 65dB...
10 @ 130dB...
100 @ 260dB..
there we go! 100 Fans...

100Fans @ 12000 CFM @ 260 dB. LMAO. WEEEEEE!
