Greetings, law enforcers!👮‍♂️ 👮‍♀️ [previewyoutube=U7H0Gi_EKLY;full][/previewyoutube] Have you ever wondered, why the police car has various sounds, when its sirens are on? Why not just use one? Previously we've shown different bluelight modes and now it's time to make this topic complete with the description of the available siren sound types.🚨 🎶 Patrol officers has a ton of equipment inside their vehicles and part of that is the emergency equipment in order to respond to emergencies. The sound, a siren, is an audible sound, coming from that vehicle to warn people around: hey, we're coming through, please yield right away! The three main sirens we're talking about is the Wail, the Yelp and the Phaser (or Piercer). The first one, the Wail, is the most routine one that we hear. You hear it on fire trucks and ambulances and described as a "wee-woo" sound — a high and a low, that's elongated in length. Then the Yelp, that is the same "wee-woo" sound, but in a faster frequency. So that when you're approaching traffic after that Wail, you can get people's attention. And then that Phaser sound, almost sounding like a phaser gun. This is from like spaceship kind of sounding stuff. This is what officers call "a traffic intersection clearer". So as you've had that other stuff on, you're approaching, you want to change up that audible sound to get other drivers attention. You get that, you clear the intersection and it's back to the Wail. If the lights are on but there is no siren, it could be that there is an ongoing crime and officers do not yet wish to alert the perpetrator of their presence. Another possibility is that, though an officer is headed to an emergency, there is no traffic on the road that needs to move out of the way 🚔 Check out the video and hear the difference 🔊 Stay on the alert and remember, that everything happens for a reason.
