Designed to emit audible warnings above 120 decibels, their sound can be heard over 2 km away under ideal conditions, warning the public of impending tornadoes. Tornado sirens are much larger and more powerful than they appear, with some models reaching over 1.5 meters in height and weighing between 300 and 500 kilograms. These sirens are installed on high poles to extend their range and are powered by electricity, often with backup batteries to ensure operation during emergencies. Despite technological advances in warning systems, they remain an essential tool in regions vulnerable to meteorological disasters.
