How loud are tornado sirens?
Erie County has 44 tornado sirens strategically placed around the area so as many people can hear them from outside their home.
Each siren has a 1-mile radius where people will likely hear the blaring noise when they're activated.
To see if you can hear one, listen for the sound at noon on the first day of each month. That's when county officials test the sirens.
The average tornado siren is 123 decibels — louder than a train whistle from 500 feet away of a jet engine from 100 feet away.
