Police Car Sirens - An Efficient Early Warning Signal Of Their Presence.

All emergency vehicles carry different kit and equipment, but there is something they all have in common and that's the siren and the lights. police car sirens sounding and the sight of flashing lights can make you very aware of what is happening on our streets and in our cities. It's a damning indictment that we do hear and see police vehicles with such regularity. Sadly the world we live in is a dangerous and unpredictable place and the police personnel need to be at the front line of any kind of emergency or where the public is in direct danger. Being on the front line day-in and day-out is not somewhere I would want to be, yet our police officers do just that in their job.

police car sirens can be heard from a great distance and when used in conjunction with lights are an excellent advance warning system. The siren is the audible warning on a vehicle and the lighting is the visible warning. Naturally police vehicles need the combination of audible and visible to cover all situations. On city streets we can often hear a siren yet don't see the flashing lights, so the audible noise draws our attention to a situation and warns us. If a vehicle isn't in our direct line of sight the lights are useless which is why vehicles need both types of warning equipment.

Many police car sirens can be used in conjunction with a microphone to use as a public address system, which doubles up their use and makes them very versatile. There are some very sophisticated siren systems that give many different sounds and options of use. Slowly creeping onto the market is a vibrating siren, now that may sound very strange but in some circumstances it has proved to be extremely effective. Instead of the sound of a police car siren the vibration models actually produce a vibration along the surface of the road and they produce a shaking effect in a vehicle ahead.

These vibration police car sirens can target an individual vehicle that seems not to have heard the normal siren or seen the flashing lights. You may thing a bank of flashing lights and loud wailing police car sirens impossible to ignore but in fact they aren't. Modern vehicles are designed to cut road noise and can shut out all other sound and render drivers unaware of what is around them. The new vibration sirens in tests can send the vibration through a targeted vehicle and the driver is left in no doubt that something needs his or her attention!

police car sirens can produce several sounds, they can have a continuous wail, an on off wail and a yelp effect. All can be used to try to draw attention to the police vehicle and advise drivers of their presence. If a police vehicle can get our attention on the road then they can get to where they need to be quickly and safely and that is the most important thing. The public need advance warning of a police vehicles approach, especially if we can't actually see the vehicle and the siren gives us that notification so we can act accordingly and let them pass.
