WOW THIS THING IS LOUD! Every single sound of the city was drowned out by this pneumatic siren, and the whole street shook. One passerby who had airpods in his ears had to put his hands over his ears because the sound was so loud, and two electric kickboarders almost fell because the sound was so sudden and strong. Awesome device!

These sirens can reach 131 dB at 100 ft making them the loudest sirens in Europe.

Oh man I can’t get enough of that wind down. I feel like this is louder than a Cyclone since the whole street shook lol. A Cyclone would only shake the ground about 50 feet from it, maybe a bit from 100 feet too

@jessetujula Год назад

Maybe, but still this was very powerful. You don't just hear the sound, you feel it strongly.

@SirensAndAlarmsOfNorthernIL Год назад

@@jessetujula I bet. It is just weird that they called the Cyclone the loudest omnidirectional siren. The larger Whelens like the 2810 and 2910 are louder than a cyclone

@SirensAndAlarmsOfNorthernIL 10 месяцев назад

It is both really. It uses a chopper disk with 4 holes in it which looks very similar to a Chrysler’s chopper and a 4 hole stator to direct the sound into 4 large horns that are inside the siren’s head, and the chopper gets supercharged with air from compressed air tanks which makes the siren loud as hell similar to a Thunderbolt but just without a roots blower

@TransistorizedCharlie 10 месяцев назад

@@SirensAndAlarmsOfNorthernIL ok, so it's like an omnidirectional 4 port mechanical siren that uses pressurized air from tanks?

@SirensAndAlarmsOfNorthernIL 10 месяцев назад

@@TransistorizedCharlie yeah pretty much just a different kind of chopper assembly that doesn’t have blades at all and relies only on compressed air like the Chrysler
