Nee Naw, quite like the sound of a dozen screaming children being dragged across a xylophone.
wooo wooo wooo wooo wooo
The CE make the S sound but are silent
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 (they 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.
The sound of an accordion is a recognizable sound. An ambulance siren is a recognizable noise.
The ambulance took Bob to the hospital
Motorcycle
Echoing of the sound off other buildings around.should be it.
When an ambulance it traveling through traffic and is in a hurry. it may sound its siren. this will cause the driver to looking the rear vision mirror. now He will see the word Ambulance backwards because that is how you see things in reflection, so by writing it backwards the driver will see the word ambulance properly and react more quickly to the situation. This is why some ambulances have this.
Yes. The A has the short A spund as in am and dam.
The Doppler Effect. It's a change in frequency cause by the motion of the sound source, the motion of the listener, or both. As a source of sound approaches, observers hear a higher frequency. When the sound source moves away, observers hear a lower frequency. This effect was discovered by an Austrian scientist named Christian Doppler. Example: An ambulance siren. As the ambulance approaches a stationary observer, the frequency seems to increase. As the ambulance moves farther away, the loudness of the siren seems to decrease.
*this is the full question not the answer* Suppose you’re standing on a sidewalk and down the street is an ambulance parked; it’s siren is a 600 Hz sound like it louder, Quieter, louder, quieter, etc. By now, you should understand that if the ambulance drivers toward you the pitch will be higher than 600 Hz. BUT HOW MUCH HIGHER? The amount is directly proportional to speed!(this means waves can be used as a speedometer!) here’s a fact: if the ambulance approached you at 8.5 m/s, the pitch would raise by 15 Hz: you would here 615 Hz instead of 600. But if the ambulance came at you twice as fast— 8.5+8.5=17.0 m/s — The pitch would raise by 30 Hz, you were here at 630 Hz sound. Question: do use the facts given above to answer this:The ambulance is moving toward you and your sound technology measures the pitch at 645 hertz. The speed of the ambulance is therefore ______ m/s.

afrequency of the same as siren frequency as ambulance is the source and the observer this is not Doppler effect problem
