The Missouri DoT plans to blast a high-pitched siren, very loudly, along with warnings to “slow down” to drivers.
The LRAD first came to prominence over the last decade, as it was found to be a non-lethal cureall for riotous crowd control, and also pirate defense. Point an LRAD at someone who finds whatever you’re doing disagreeable, fire the sucker up, and suddenly they are blasted with up to 153 decibels of noise.P
And how loud is 153 decibels? Well, lets put it this way: a standard-issue firework, if there is such a thing, exploding three feet away from you is slightly quieter. A Boeing 747 taking off right next to your head is much quieter.
