Words that have two distinct meanings can be confusing but there really is no way to confuse the siren of the sea with the Police car siren. One lures people to their death and the other potentially saves lives, so they couldn't be further apart really. It isn't just police cars that need sirens as any first response or emergency vehicle will have need for a siren to accompany their flashing lights in emergencies. We do often hear a police cars approach long before we actually see it. The sound of sirens echo round our towns and cities and sometimes it seems that's all we do hear.

When you hear a Police car siren you can be sure that they are in the near locality and are attending a priority code call. Only the most urgent of calls will demand that lights and sirens be used, in many cases only lights will be deployed and in the majority of calls the officers will not need either lights or siren. Sirens are important, as we often can't see the flashing lights of a police vehicle on our streets, we can't see round corners but we can hear round them. Flashing lights warning of something are useless unless ...
... they are in your line of vision.

The thing about sound is we can make fairly accurate judgments of how far away a Police car siren is, and that gives us the opportunity to alter our course. Police car siren units do produce different sounds, you get the constant repetitive woo-woo sound and also the short sharp yelp sounds. New to the market are sirens that don't produce a recognizable siren sound but a vibration. These new sirens are to get the attention of people on the roads where all else has failed. Many people are so hermetically sealed into their cars that virtually all outside noise is cut out, and in that kind of situation they don't hear sirens.

The vibrating sirens can be used in conjunction with ordinary Police car siren units and are a very good backup system. The vibrating siren types produce a very low tone, which can be targeted on a specific vehicle. In the tests carried out so far they have been very effective in getting drivers attention when all else has failed. Sirens are a necessity on police vehicles and they do help maintain the safety of officers and the public. The need for Police car siren units has not diminished and when used correctly they can help officers get to urgent calls with utmost speed and safety.

Whether Police car siren units are vibrating or the general variety they do have a very big role to play in safety. Lights are good hazard warning and they do convey a sense of urgency, but the sirens get our attention and hold our attention. Lights can mesmerize and blind people and obviously if people can't see then they don't see the flashing lights. Audible warning is as necessary as visible warning on all emergency vehicles and never more so than on police vehicles. Listen out for sirens when you are driving and take appropriate action if you hear any.
