Not sure why more bicyclist have not mounted or used air horns to keep them save, like cars, but with Airzound they could change that. All of us have close calls, yelled, screamed #$*&#@ at motorist. Airzound is trying to change that and also claims it is the worlds loudest bike horn at 115 db.
On the decibel scale, the smallest audible sound (near total silence) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1,000 times more powerful than near total silence is 30 dB. Here are some common sounds and their decibel ratings:
Near total silence - 0 dB
A whisper - 15 dB
Normal conversation - 60 dB
A lawnmower - 90 dB
A car horn - 110 dB
A rock concert or a jet engine - 120 dB
A gunshot or firecracker - 140 dB
So by How Stuff Works the Airzound is just above a car horn, so people should take notice since it will be a little louder and different.
Really the horn should have someone screaming as though they are getting run over that would really jolt drivers to be more aware.
