Need a LOUD horn?

The GTS listserv has had a recent discussion of the Stebel Nautilus Horn.  Claimed 139dB!  Should make even cell phone using Escalade / Navigator drivers take notice.   ;D  Not good for a quick "beep" type hello, though.

Check out the link:  www.twistedthrottle.com/trade/productview/2137

Kind of glad I haven't ordered the 130dB Fiamms yet.  Should fit up inside the fairing someplace.  Not very big - especially for an air horn.  The compressor is attached to the horn itself.  Dimensions are  5.9" (150mm) x 4.4" (112mm) x 3.7" (95 mm).

If you have an accident on a motorcycle, it's always your fault. Tough call, but it has to be that way. You're in the right, and dead -on a bike. The principle is not to have any accident. If you're involved in an an accident, it's because you did not anticipate. Then, by default, you failed.

I've got horns under my fairing fom a Ford Taurus, but you can use horns from any large car (Caddys or Lincolns are good choices)

You must add a relay though becuse the stock horns are switched on the ground side & if you try to use them straight off the horn button, you'll melt the spring behind the button (don't ask how i know this)

Cool.  A pneumatic jackhammer is 130dB.  a 10pt increase in dB represents almost a doubling in total sound so the horns are pretty darn loud.

;D

I especially like the fact that you can see the effect of the soundwaves as they hit the camera. That, my friend, is a cool wave physics lab!

Holy Crap!!!  If I accidently hit that it would probably knock me off the bike! A horn like that could get you shot in some places!

Kinda like how they shatter kidney stones with sound waves.  You may be onto something mutt. ;D

Dave - I am a radio guy in the Air Force and what we were taught in our school is that every 3db increase the total output power doubles.

H2O - That is just insane.  139 decibles could cause some serious hearing damage.  Is that thing even legal??

3db is correct for a doubling in power.  It's a logarithmic scale.

130-135 dB is the approximate dB level of our tanker's engines as they are taking off from the runway.  :o The recommended exposure time for anything that loud is like 10-15 seconds!  So anybody that has a horn like this make sure you don't have it on for too long, and don't sound it off in your garage!

I stand corrected. ;D ;d

I was digging back to my early car stereo days in the 80's and early 90's and all the "SPL" contests I entered.  Musthave squished a few memory cells in the old noodle. ;D

Not sure if I am doing this right, I am medicated (bronchitis) so I am a little bit foggy headed but here goes.

0dB is equal to 1mW (.001 Watts) of power, and at 138dB the equivalent power level is 70,368,744,177.664 Watts.  That is quite a jump in power level.   :o

PS - if there is anyone who knows if I am doing this wrong please feel free to correct me.  ;)

The horn has dropped down the list of purchases for now, but I will likely get one sometime this summer.  Don't care about the legality, I just want the idiots in their air conditioned cages with the cell phone glued to their ear to know they did something stupid.  I don't use the horn very often, but when I do, I want to be heard.  This horn takes up less room than a pair of FIAMM Freeway blasters & is 9dB louder.  What the heck, I normally ride with earplugs anyway.   ;D
