Hell's bells - a bicycle louder than Concorde

As it is a bit late for April 1, we have to assume that the announcement of bicycle horn that is literally deafening is for real.

The ironically-named Airchime horn comes from an American locomotive and is said to be louder than an F14 on take off with reheat. At a distance of 50 feet the F14 produces 130 decibels, but the bicycle, called the Hornster, can produce 140 decibels. In comparison, typical city traffic is 78 decibels.
