When you notice how loud a police siren wails today, you might start thinking about what exactly makes this so loud. Considering the fact that there are no sirens attached prominently on the car, it definitely is impressive that such a loud sound can emanate from it. There are multiple concepts at play here, and knowing about some of them will give you a rough idea about the police siren and what exactly pushes it to sound the way it does. You will most definitely be impressed with this technology and might even think about some other way in which it could perhaps be used.

One of the things that make today's police siren really loud is the fact that it is digitally driven audio system, compared to the analog systems used in the past. Therefore, you will most likely not have heard to anything so loud mounted on the outside of a vehicle. The digital process enables a higher output to be produced without consuming as much power in the process. This is perhaps the strongest reason why more components in the police car, including the police siren, are going digital. The whole process is a lot more ...
... efficient.

The other thing that is responsible for boosting the volume of the police siren is the fact that the speakers are more focused and sound clearer for farther distances. Hence, with a better speaker design, it is unlikely that you are not going to hear the siren, even if you are miles away. This is the other big advantage that makes the police siren such a prominent presence while on the road. You will be hard pressed to find something else that could even remotely match the sound that these sirens can produce, including your cars high end audio system!

If you were to talk about volume, the decibel levels that a police siren has steadily increased over the past few years to new regulatory levels. Now, the levels are more or less stabilized thanks to regulations that dictate the maximum level that a police siren can produce without extensively hindering other motorists on the road. In this manner, drivability is not affected and people can continue using the roads even with a police siren blaring down on them. All in all, this helps in maintaining harmony while ensuring that the police can get the job done with ease.

Therefore, it is safe to say that while the police siren is considerably loud today, it is not so that you cannot concentrate on what you are doing when you do hear it. Ideally, you would want to yield the way to the police officer and ensure that you are not in harm's way. In this manner, you will be safe and should have no difficulty in dealing with other hazards while on the road. The police siren, although invisible to the eye, has come a long way to ensure that you don't pay the price and get careless when on the road.
