Advantages and Disadvantages of the Siren
This article investigates the siren and its uses. We will look into what a siren is used for as well as explore how the siren works. We will look at advantages and also reveal some of the drawbacks. The main focus is on the siren and its application on police cars.
The siren has been a momentous development for emergency purposes and this article will specifically look at how its use has been developed for police cars. Although the siren is used for a number of areas such as for warning people of danger, the most effective use has arguably been found in police vehicles. Police vehicles use a siren together with police lights for the purpose of warning motorists of their approach. Motorists are always expected to give priority to police vehicles that are responding to an emergency and can be recognized by the sound of a siren.
Police vehicles use a siren with the main goal of signaling their approach. Although police lights are also used for this reason, a siren is more effective as it can be heard a long time before the actual police car is visible. This gives drivers more than enough time to react appropriately as this is essential due to the high speed associated with police cars responding to an emergency. The siren needs to be loud and clear, and there are specific sirens used for use only on police vehicles. This identifies sound as an approaching police car and cannot be confused with a siren used for any other reason.
A standard siren found on a police vehicle is set to produce a louder sound when approaching an intersection. Since police cars are exempted form certain traffic rules, it is particularly important that the siren is louder at intersections to alert other drivers that the police vehicle has the right of way. Most police cars today use the electronic siren as it produces a much clearer sound than the more traditional sirens. The volume of an electronic siren can also be adjusted by the driver to match the urgency of the situation, thus in turn giving police officers more control over the siren. There have been new developments such as ramblers and howlers that besides producing a loud noise send vibrations through other vehicles to better convey the urgency of the situation.
There is however disadvantages associated with the use of a police siren. Metropolitan cities are characterized by noise from motor vehicles, motor bikes, factories, entertainment joints and many other places. Police sirens add to the sound pollution in cities, a nuisance that most governments are trying to deal with. Police sirens are also known to cause panic among drivers when they are turned on suddenly. This has resulted in a considerable number of accidents especially among new drivers or drivers that are easily frightened. They are also a nuisance to people who live in and around cities as police vehicles with blaring sirens is a common sight.
The police siren if heard constantly can cause hearing problems. Although police officers are advised to use ear protection when they are using sirens, there are no such remedies for people around and this can cause them hearing problems in future, especially those who are constantly exposed to the sound. For people with blood pressure problems, the sudden sound of a siren can cause their blood pressure to shoot up, which has serious health repercussions for the individual. Although the police siren has helped to improve the efficiency with which police officers respond to emergencies, there are serious problems associated with their use. More research needs to be conducted to ensure that the problems are reduced or solved all together
