Emergency siren vehicle (Dorset Ambulance)
Introduction
Each and Every-day occurrence for many drivers they here sound of an emergency vehicle siren, that might be from an ambulance, police car or fire engine. Emergency siren vehicle transportation is allowed after you had a sudden medical emergency, when your health is in danger conditions. When emergency siren is heared by drivers or passengers they look across and they will try to check from which way the sounds are approaching. There should be hint from which vehicle the sound is approaching as sound exclusively cant give any clue from which direction the vehicle is arriving. Because of these reasons drivers are not able to take appropriate preventing action till the emergency vehicle is seen, Mean while it is too late clearing the path and allowing the emergency vehicle (Patterson 1982).
This unawarness may costs lives. If there is any improvement in the sound quality of the siren, it helps to take avoiding actions before by the drivers, it will be also help in reducing the journey time and also enhance the safety for emergency vehicles which take care of emergencies and therefore increase the service supplied. For these preventive measures Dorset ambulance which is used with the Localizer or well known as White Noise Siren system is used.
Localizer sound comprises of broadband, multi-frequency with white noise sound. This sound can be well heared by our ears, so that we can identify the location from where it is coming from so it is helpful for the fast evacuation application. It is built up at Leeds University.
When compared with other fire alarms like conventional fire alarms they only give caution to the people to evacuate the building when a fire falls o...

In severe times such as the six miners missing by the Cave in at the Crandall Canyon coal mine in Utah, sound is an effective way to know the existence of the miners.
These include phonemes (individual sound units that are used to
Everyday there are hundreds of ambulances, fire engines and police cars being called to the scene of emergencies. I’m sure you hear the roar of their sirens, but you don’t think twice about them and are able to tune them out. The only time most people even think about the sirens is if they are forced to wait at a light or move over to the right shoulder and let them pass. When you look back and think about those sirens, where do you suppose they are going? Most people probably think that they are going to a car accident with entrapment, or a person with crushing chest pain to try and intervene and get them to the hospital.
and sounds that this can create are put to good use to add to the
Ambulances, started to affect today’s modern health care after the Civil war. Ambulances are specially equipped motor vehicles. Ambulances carry sick, or injured people from the spot of their accident, to the closest hospital. Ambulances are part of the emergency medical services, EMS, which also includes helicopters, airplanes, and boats. Ambulances typically have room for one or more people. Ambulances can also hold many medical personnel and medical supplies.
...orthy (2012) completed a narrative review. This article was not classified as a systematic nor integrative, although the research was comprehensive. Edworthy (2012) completed a review including many of the traditional medical literature databases such as PubMed and Web of Knowledge. She additionally searched in the PsychINFO and human factor journals. Her strategy was to examine the available research specific to auditory alarm response time. Fifty eight articles were cited in this review. This article represented a comprehensive narrative by an expert in the specialty area. The author had twenty-five years experience as a researcher and designer in the area of audible alarms. Her findings suggested a significant improvement in response to alarms when greater emphasis is placed on the alarm design (Edworthy, 2012). She recommended standardization of alarms.
Although level noise do not reach OSHA level (occupational safety & health administration) that causes noise-induced hearing loss, the paediatric nurse in the unit are exposed to continuous moderate noise levels that may causing impairment (Berens, 2008). In addition, these noise exposures may result in abnormalities in the stress response as well as in sleep patterns. (Berens, 2008). If working long shifts weekly and being exposed to noise it will have an effect on hearing loss. The loss of hearing depends on how loud the sound is and the length the person is exposed to sound. Exposure to high level of noise and sound can cause deafness. During or after being exposed to loud noise can leave a ringing sound in the ear. Noise will interfere with communication which could lead to misunderstanding of orders. This could lead to a higher risk of accidents when communication is

It is a huge responsibility to drive a car and one which should not be taken for granted because it is associated with the lives of others. By speaking on cell phones while driving, such a responsibility is treated with impunity and the dangers ignored.
When a sound is made a vibration is sent through the air. The vibrations are let off by the source, and this leads to something such as an ear to pick up the noise. Once the detector has picked up the wave, the wave must be ...

Nevertheless, hands-free phones are just as disturbing as hand held phones. They both serve the same purpose when it comes to distracting the driver from state of the road. Thus, hand held devices do not increase safety, and I have observed this when using the cell phones as I drive. At the same time, I have noticed that my reaction time significantly reduced, and I almost caused an accident. When I look at this slow reaction, I compare it to that of an old...
