Apart from scaring dogs why would a cyclist want an air horn this loud?
Surely it might give someone a heart attack if you are approaching them from behind.
Well if you obstruct the horn a little, I use a piece of old inner tube, it gives a much better horn sound than previous and is probably in the range of about 50db, rather than the 114db it normally gives out.
The reason I bought this horn is because i was on my 3rd bell and they were still a waste of money.
The standard Pro-Connect bell was useless, the 2nd was a electronic bell.
Louder than the other, though still useless.
Then followed a larger (classic) bell, and again, no pedestrian heard me coming at all.
Depending on how fast you are travelling and other factors like the wind or street traffic, most of the time the conventional bells are just a waste of air.
The airzound on the other hand can never be unheard and like i said with a bit of DIY you can change the db to suit your needs.
I leave the inner tube in the horn in rural area's and take it out for full db in the city where you do need it.
Its a very adaptable system.
Hope this answers your questions.
Bob.
