The sirens have an effective range of two miles in diameter. At 100 feet, the sirens are heard at 129 decibels (the equivalent sound level of a jet engine taking off).
Small, light, and big units of these electric sirens emit audible, high-pitched, medium-standard sound waves that can be heard up to one mile away…
The siren has an output of 138 dB(C) (30,000 watts), and can be heard as far as 25 miles (40 km) away. In 1952, the cost of a Chrysler Air-raid Siren was $5,500 (Equivalent to $61,851 as in December 2022). The United States government helped buy sirens for selected state and county law enforcement agencies.
Ranging from a 2.5- to a 5-mile radius, the sirens are activated during periods of tornado warnings.
Studies have recognized that sirens are a limited warning device and effective only at very short ranges and low speeds. At speeds above 50 mph, an emergency vehicle may “outrun” the effective range of its audible warning device.
Most accidents involving ambulances occur at intersections. It turns out that drivers coming into an intersection that crosses into the ambulance’s path cannot hear the siren until it is about 80 feet away.
The sirens are powerful, but they have one weakness: if anyone hears them and survives, they will die.
The physics of sound will reduce the volume of the siren as the distance from the siren increases. With today’s modern vehicles, the effective range of the siren at a 90-degree intersection is often no more than 80 feet.
Based on the analysis of data collected by Storm Track, the average distance at which a tornado becomes audible is 1.5 miles. The maximum distance is about 4 miles.
The National Weather Service has determined two weather conditions for siren use. A steady tone, lasting 3 minutes, means a tornado watch or a severe thunderstorm watch. A wailing tone (6 sec. Hi/6 Low) lasting 3 minutes means a tornado warning or severe thunderstorm warning.
Weaknesses. Bronze dagger and victim’s blood – The only way to kill a siren is to stab it with a bronze dagger dipped into the blood of someone it has infected. The death of a siren releases its victims from its hold.
Install window inserts. If you live in an environment with heavy noise pollution, such as honking car horns, wailing sirens, or music blasting from next door, utilizing soundproofing window inserts is the most effective way to reduce the cacophony.
