Can you be up for legal charges while driving an ambulance by blowing horn setting off a siren for passing someones house if not in route to a Emergency Call?
you are not supposed to use the siren unless it is an emergency, i dont know that they would make a big deal out of it if you were just doing it in front of one house unless there was a big deal made out of it.
Answer . Siren as in audible warning signal? 'Blockbuster' by The Sweet. Siren as in "woman whose song lures sailors to destruction"? 'Lorelei' by the Tomtom Club.
ANSWER: . Because when you see it in your rear-view mirror, It reads AMBULANCE, and you know to pull over to let it pass.
They have a siren so that they can alert motorists to the fact that they have to get past traffic to get to their destination as fast as possible. Motorists are suppose to pull to the side of the road to get out of the way for them.
If you are standing on one side of a building how can you hear the siren of an ambulance on the other side of a building?
The sounds reflect off of other surfaces.. Usually the reflective sounds will create an illusion that they are coming from every direction. That's why city ambulances running lights/sirens often get in accidents, is drivers don't know where they are coming from and don't yield.. Sirens are really … loud ... ( Full Answer )
Depends on patient condition. If there is an immediate threat to life or limb, then the lights and siren should be used. Otherwise, they shouldn't. They come with an inherent risk of distracting other drivers and possibly causing accidents, and in today's "I'm the most important person in the world"… society a lot of people won't even pull over anyway.. Oh, and everywhere has the same laws - if you're running either lights or siren, you run both. Never run a silent lights, because it's illegal. ( Full Answer )
When the vehicle is moving towards you, the sound waves are shoved in front of it, and that makes them sound higher-pitched - then, after it has passed and is moving away from you, the sound waves slow back down and you hear the pitch drop.
To alert the public that they are responding to an emergency. The public must "Make Way" for the truck to pass safely.
The Sirens were young and beautiful bird-woman (similar to harpies) in Greek Mythology who lured sailors with their enchanting voices. Sailors entranced this way dove into the sea to be with the Sirens, or sailed their ships into the rocks and to their death. The Sirens are most famous for being in …Homer's Odyssey where they tried to lure Odysseus on his way home from Troy. They were given wings by Demeter to look for Persephone when she was taken as the sirens usually accompanied Persephone. They were considered the daughters of the river god Achelous, fathered upon Terpsichore, Melpomene, Sterope, or Chthon. ( Full Answer )
Go out and buy a World War 2 documentary. I remember once as a child hearing the air raid sirens all go off in wakefield, UK. Yes you could go and buy a video from world war two, you could search 'carter air raid siren' on the web... Carter being the UK air raid siren, and that will be close. It is… a two tone siren that raises and falls in pitch, but they do not have the effects caused by space, there are some Doppler effects from sirens further away, and the whole effect is more mournful than you can imagine, stood in the streets very late at night with this siren wailing from our local town hall, the echos from the town and village halls in surrounding areas..... and other small groups of people stood in silence apart from the wailing of the sirens.

Sirens are either Greek mythological monsters that lullunsuspecting victims by singing to them OR loud, screechingmachines that are used to indicate the danger of a certain area.
Diffraction causes you to hear the ambulance on the other side of the building, even if you can not see it.
One common spelling is "whoop-whoop" (woop-woop). You can approximate a European-type siren by repeating the word "wiener".
The velocity of sound in air is 343 ms An ambulance is traveling east at 64.9 ms Behind it there is a car traveling along the same direction at 29.8 ms The ambulance driver hears his siren at a?
afrequency of the same as siren frequency as ambulance is the source and the observer this is not Doppler effect problem
The Sirens (Greek Mythology) lured sailors with beautiful music, and made them either throw themselves into the sea and drown or crash into rocks, and die. Modern day sirens produce loud noises to alert people from far distances.
because you get closer to the sound . As the ambulance gets closer, the sound waves are compressed relative to the person; so the frequency increases..
Speed of sound is approx 740mph a police car with its siren sounding is approaching you at 80mph at what speed is the sound from the police siren approaching you?
The sound moves through the air at 740 mph, regardless of the speed of the source. The sound of the siren passes you at 740 mph. However, since the source is approaching you, more waves pass you each second than leave the source each second. That's why the pitch of the sound from an approaching sou…rce sounds higher than its actual pitch. Also ... since the sound doesn't move away from the source any faster than 740 mph no matter how fast the source is moving, that's why the pressure of the sound waves piles up in front of the source when the speed of the source approaches 740 mph, forming what's popularly called the "sound barrier".

What conditions would have to be met when an ambulance with its siren on not to exhibit the Doppler effect?
If the ambulance was moving either towards you or away from you it would exhibit the Doppler effect. \n \n \nI.E. Higher pitch if it was moving towards you and lower pitch if it was moving away from you. \n \n \nThe change is most noticeable if the vehicle passes you. Presumably more noticeable w…ith lower frequencies than higher frequencies. ( Full Answer )
Quickly BUT SAFELY move to out of the way.If you cannot do so immediately,DO NOT PANIC do it when you can.
The air raid sirens sounded when approaching bombers were picked up on radar or were seen crossing the coast and heading for large cities. The sirens warned people to head for air raid shelters or to take cover in their own homes. When the danger was over, the sirens sounded again with a different t…one to signify 'all clear'.

After an approaching ambulance passes a stationary observer what does the frequency of the sound of the siren heard by the observer appear to do?
It decreases. This is not just apparent. The frequency emitted by the siren is constant, but the frequency arriving at the observer really does change.
It means that the person in the ambulance is not critical, but they still need to hurry and get to a hospital..so it's just a "let us through" kind of thing.
Activation of lights OR siren indicates that there is an emergency . Please be courteous and assume nothing else or lives can be jeopardized. While local laws may vary , the general rule of thumb is... 1. All drivers and pedestrians should attempt to safely move to the side of the road (movi…ng right is typically accepted unless the ambulance is using the right lane to pass). 2. After safely moving from the lane of travel, bring your vehicle to a safe stop . This applies whether the ambulance is behind you or approaching from the other direction. If the ambulance is approaching you and has to turn left, waiting until the last minute will delay their response or cause you to hard brake. Hard brakes may cause you to be rear-ended. 3. Never speed up in attempt to outrun any emergency vehicle. 4. Do not panic and slam on the brakes. 5. Do not assume that the ambulance should go around you. While transporting a patient, medical procedures are occurring in the back. Changing lanes creates unnecessary motion that can delay or prevent procedures from being completed correctly. That said, if the lights are activated without a siren, it is possible that someone just forgot to turn the switch off. It's uncommon, but it does happen sometimes! Don't fail to yield right of way if you see this though, because: 1. We do what is best for the patient. It may still be an emergency. The siren may have deactivated en route to an emergency or while transporting. The best decision for the patient may be to carefully transport with lights only, instead of waiting on another ambulance that is far away. 2. We try to keep everyone happy. Some communities complain about sirens, so they are used intermittently in attempt to please the public. This is especially true in residential areas during late night hours. Hope this helps you help us help others. Take care! ( Full Answer )
Often, there was an "all clear" signal, a steady tone from the siren, for about 7 - 20 seconds.
The printing is reversed when viewed in a rear- view automobile mirror and it will look correct.

no its not my freind has it and he talked back to the police when they told him to turn off the car
As long as a player doesn't touch the ball after the siren sounds the basket is good.
An ambulance is going down the street with its lights and siren on the hospital is five blocks awayselect all the statements that are observations?
the ambulance is going to the hospital the ambulance has its siren on the ambulance is moving (: PJHS
Odysseus displays craftiness, wiliness, and foresight, as well as an appreciation of the fine arts.
why a ambulance has a siren a ambulance has a siren because if someones about to die from being stabed and the ambulance is caught in traffic the person will die so a siren will create a sound that the cars in front can hear they'll move out the way so the ambulance can get to the person fast
Both lions and tigers "roar" or "growl". But the cougar, cheetah, and some other smaller cats have a distinctive higher-pitched "yowl" instead of a roar.
The effect that you are hearing is called the Doppler effect. Sound is created by vibrations in the air. The faster the vibration, the higher the pitch of the sound. When the fire engine is stationary, we hear the sound waves at the same rate that they are being generated. When the fire engine is… coming towards us, the vibrations reach our ears at a faster rate than they are being generated. That is because the distance from the fire engine to your ears is reducing. As the fire engine passes and moves away, the distance is increasing so the sound waves are reaching your ears at a slower rate than they are being generated. The Doppler effect can also be observed in light and radio waves and is one of the techniques used to measure the expansion of the universe, commonly called the "red shift" ( Full Answer )
The sounds of tornado sirens may vary slightly from one area to another. Basically, a tornado warning siren has an eeire wail. One could hear the sounds of tornado sirens on numerous YouTube videos.
Is there a law that states that the emergency services can not sound their siren after a certain time of day-night?
No. In most states their are laws that list the Db levels, and how high those levels can be at what time of the day. In nearly all of these laws emergency services are exempt, including; police cars; fire trucks; ambulances; fire alarms; tornado sirens; and other emergency service's that are noisy.
the sirens tell people that a car is coming also it sends a signal to stoplights for a go.
When ambulances are responding to a Priority One job (urgent situation) they activate the sirens and warning lights to alert other vehicles to let the ambulance through. The ambulance siren can be set to a variety of different sounds and volumes.
It is spelled backwards on the front so that cars in front of it can read the word the right way around using their rear view mirrors :)
What scientific term would be used to explain how an ambulance siren sounds different as it approaches you then when it moves away?
The Doppler effect. It defines the relative change in frequency and wavelength of any waveform perceived by the observer when the observer is at a distance from the source and not with it. Check out a flash animation to understand this effect better.
Nee Naw, quite like the sound of a dozen screaming children being dragged across a xylophone.
When an ambulance with full lights and sirens travels a bumper to bumper highway what should motorists do if they cannot move to the shoulder of the road?
Many highways become so busy that bumper to bumper traffic makes it nearly impossible to move to the shoulder of the road. When an ambulance approaches from the rear and motorists are in bumper to bumper traffic, the motorists should STAY PUT. The ambulance will use the shoulder (on left or on the m…edian side) to maneuver around stopped traffic. NOTE: This is another reason that motorists should never use the shoulder to pass stopped traffic on any US highway. Emergency vehicles need the shoulder to be clear of all obstacles so the emergency vehicles have an open way to pass. ( Full Answer )
This is the doppler effect. If an ambulance is driving towards Jon, the sound waves are tightly stacked in front of the ambulance and are heard by Jon at a high frequency (high pitch). But behind the ambulance the sound waves are lagging because the ambulance is driving away from they sound waves (t…hey are moving in the opposite direction) thus if Jon was standing behind the ambulance the frequency heard would be low (low pitch). The actual sound an ambulance makes is actually obnoxious, and if 100 of them drive by someone's apartment each day, it will make their head hurt and they will often think about why ambulances are so annoying.

A siren will drown you but no worries it is a mermaid and mermaids are myths and myths are not real.

It depends on where you are in the world. In the US, most ambulances sirens have 2 or 3 settings....a long, slowly ascending and descending Whooo sound, a short rapidly ascending and descending warble tone, and sometimes a 3rd, higher, louder, phazer sound (my favorite to get attention of complace…nt drivers). Rarely , US rigs will have a European, up/down, British, DA/da/DA/da/DA tone. We have 1 rig at our department with the rare European setting. I love to use that setting through intersections here in the US just to mess with people, because most Americans have never heard that tone, except in movies. Ambulances in the US also have either a genuine air powered horn (awesome), and/or an electronic simulated air horn sound (lame). If you pay attention, before long you will able to tell the difference between police, ambulance, fire engines, and personally owned emergency response sirens just by the subtle sounds of each siren. The loudest, best siren is the air powered siren on the Fire Engines. They are controlled by a foot button located on the floor of both the driver and passenger/officer seat of the engine, an air pump, and a big, loud, steel speaker horn. They are easily the loudest siren available. Some police cars in the US have a "Rumbler Siren" that bottoms out at a subsonic level to send shock waves into the ground and surrounding areas, so that even if you have a crazy loud stereo cranked up in your car, you will feel the police siren in your bones....pretty cool. Ambulance sirens are usually between 100 and 200 watts of powered sound, and about half of the drivers on the road are completely oblivious to both lights and sirens until you are really close. When you see emergency lights behind you with a siren in America, pull to the RIGHT and stop. They will always pass you on the left in the US. If it a cop, you will notice blue lights. It is very rare for any other emergency vehicles to employ blue lights in their ensemble...and usually illegal. If an unmarked police car attempts to pull you over, call 911 and verify the identity of the unmarked car before pulling over, or drive to the local PD if it is close. Although illegal, it is not hard hard to obtain emergency lights in the US, and is a tool used by criminals to pull over victims. Rare, but it happens. ( Full Answer )
The Doppler effect occurs when someone is standing still listening to a siren going past. If the paramedic is in the ambulance, then there is no Doppler effect for him. It is all relative to who is moving and who is watching.
Ambulances are commonly staffed in two person crews. The type of licensure these people have depend on the type of ambulance they are operating in. There are two different types of ambulances: Basic Life Support (BLS) and Advanced Life Support (ALS). A BLS truck is staffed with at least one EMT-Bas…ic or sometimes, an EMT-Advanced. The other crew member is either another EMT-B, EMT-A, or an Medical First Responder (MFR). A BLS truck is equipped to deal with most emergencies but will not have all the capabilities of an ALS truck. ALS trucks are staffed with at least one EMT-Paramedic, and either an EMT-B, EMT-A, or another EMT-P. These trucks and crew are trained in advanced methods such as cardiology and pharmacology and are able to do things like EKGs, start IVs and administer drugs, and intubate. An ambulance will always have at least an EMT-Basic, and most ambulances are ALS, meaning they have at least one Paramedic at all times. ( Full Answer )
There should be sound clips online that can be downloaded. Alternatively, for the real thing some war re-enacting societies will most likely have one and use it ate their re-enactments or knowing someone in such a society it may be possible to twist their arm into "stretching its legs".
The first A has a short A sound as in am and ample. The U andsecond A have schwa sounds.
Why do you hear a higher pitched sound when an ambulance is moving toward you and a lower sound when an ambulance is moving away from you than you would if you and the ambulance were both at rest?
That's called the "Doppler" effect, named for the scientist who explained it. You're standing still, but the train or ambulance is moving toward you. The horn or siren is going. The sound waves go out in every direction, at the speed of sound (about 750 miles per hour, depending on atmospheric pre…ssure). As the train is moving TOWARD you, the sound waves that it generates are being pushed together, because the train is moving too. We hear the effect as if the frequency of the sound waves is pushed together, increasing the frequency. As the train passes by, we hear the "Doppler shift" to the lower frequency, because how the train is moving AWAY and the sound frequencies are stretched out. Now we hear the sound at a lower frequency. If we carefully analyze the Doppler shift, we can determine; 1. Exactly how fast the train was moving 2. How far away the train was when it passed by. Police use the same thing; you're driving along the highway, and a police officer points his radar gun at your car. The radar gun is precisely calibrated for frequency. The radar waves hit your car and bounce off, and the Doppler-shifted frequency can be used to calculate how fast you were going. ( Full Answer )
