fun with a decibal meter
 

we have some cool stuff here at work like a truck scale, a temperature gun and a decibal meter among other things. every time i get bored i check my cars weight, look for heat soak in different places and tonight i used the new decibal meter. i registered a peak of 95db at idle and 121 at WOT. as reference, conversation is 70db, a chainsaw is 100db and a jet taking off at 200ft is 120db. oh yeah this is with stock manifolds, hollow cat and a magnaflow catback. ill have to try again when i put on my mac mids with high flow cat. whats the state law on exhaust noise?! anyone ever wants to come down and use this stuff feel free on the weekend let me know im in camden county.

yo dude, haha yes, let me, with my longtubes and no cats and loudmouth :)

whenever you wanna come over on the weekend, let me know.

well maybey not this weekend. lol car show weekend hmmmmm maybey another time though

you goin down? what day?

how did you measure it?...iirc, you have to do it 50 feet behind the car or something like that

i think thats how they measure it at the track, from 50 feet away.

i had it about 1ft from the pipe. if they do it from 50 feet away i cant imagine to many streetable cars being over the limit of what 90 or so.

I'm down! Sounds like fun.

well you could probably yell into the thing from 1ft away and get a good number of decibels

yeah, osha regs are a little strange. you need earplugs if you are in an area with a db reading of 85 or over yet i was talking with the meter down by my chest a foot away and my voice was averaging around 87 or so. go figure.
