Nah, its correct, the dB scale is a logarithmic curve, every increase of ~3dB equals a doubling of sound intensity, its not a linear scale.

Seano.

Seano is correct but the hearing brain system of our bodies will not really detect a 3 and even greater times increase in loudness at these levels. Our systems are not this senstive.

I like this horn better.

BEHEMOTH INLINE TRIPLE TRUMPET CHROME TRAIN AIR HORN:eBay Motors (item 280343827551 end time Jan-04-10 15:11:26 PST)

If one devise creates x db, will two create 2x or x? ie are db produced in series or parellel?

So has any one decided which is the best one ?

(I hate the standard horn).

(Thinking back to 1st year physics...) I am pretty sure you get twice the intensity, and hence an increase of ~3dB. But as Garrycol mentioned, we aren't too sensitive to such a change, it would probably be a noticeable difference but not too significant.

As for which is best, I vote the train style horn Slunnie has a link to. ALTHOUGH... Ron's (101Ron) actual compressor driven air horn is probably better than the lot

Got any pics of you in a tartan skirt?

Sorry to disappoint but no!

But I have worn one!


And I don't smoke a pipe on the bike, but have smoked cigars whilst riding!

But Ron's don't work too well when it is full of sand or water.
