well, i was recently looking at fans for my case.
i have a handy chart for figuring out dba of multiple different decibel level fans. kinda got sick of calculating it each time so i made a program that calculates fan dba in pairs.
i could have interpolated the table or even used the original equation, but numbers are so small.. and i'm lazy.
but it helps..
i sent it out to my friends who think because they have 4 30dba fans, their case is 120dba (Jet engine? )
i have the c++ source and proggy in the same file just incase u guys don't trust me u can look at the code and compile it yourself.
Also, if u have a 50dba fan and a 20dba fan and put it in the program, you'll get 50dba! why? anything over a 10dba difference will increase like .1 dba.. didn't bother putting that in the data array, pointless.
I hope uploading my proggy doesn't violate forum rules..
i didn't find anything about that in the rules section unless it slipped by me.. if so, i aplogize and will delete the thread

sorry for using forum bandwidth at first
