Herr Doppler noted that the pitch is higher as the object approaches and lower as the object departs.

The change in frequency of sound waves in the Doppler effect is heard as a change in?
Whenever the frequency of a sound wave changes, regardless of what caused it to change, the change is perceived as a change in the pitch of the sound.
How does the pitch change when the loudness of a note changes?
When the loudness of a note increases, the perceived pitch does not change. However, if the loudness of a note decreases significantly, it may start to sound quieter and could appear to lose its pitch as it becomes less audible. Nevertheless, the actual pitch of the note remains the same.
What causes a sound to change pitch?
A change of pitch in a sound is caused by a change of wavelength. This can be caused by a change in length or size of the vibrating or oscillating device or system causing the sound. When you press on a guitar string at one of the frets, for instance, you shorten the vibrating part of the string thereby shortening its wavelength and increasing its pitch - shorter wavelength = higher pitch.*The pitch of a sound can also be changed by movement of the sound source away from or toward the listener. This is called Doppler effect. Moving away, the waves become stretched resulting in a lower pitch, and vice versa when moving toward the listener.*Keep in mind that all sound waves travel at the same speed, so shorter wavelengths will reach your ears in greater numbers per second than longer wavelengths. This is called frequency. Higher frequency = higher pitch and, again, vice versa.
If an emergency vehicle passes you in traffic just as it passes you the pitch of the siren changes This is because?
frequency.
What is it called when the change in pitch of a train's horn as it passes while you are standing still can be explained by?
The change in pitch of a train's horn as it passes while you are standing still can be explained by the Doppler Effect. Just as any other horn or fast moving sound, When a object emitting loud sound is coming towards you, the sound is compressed and sounds like a higher pitch. When the object is moving away the sound is expanded sounding like a lower pitch.
How does perceived pitch change as a sound source passes a listener?
The perceived pitch of the sound drops (frequency decreases) as the source transitions from approaching the listener to receding from the listener. The phenomenon is called the "Doppler shift", after the German Physicist who explained it and worked out the math.

What is the relative frequency of a sound as perceived by a listener?
I think you mean pitch.
What cause the pitch of a sound to change?
The frequency of the vibrations. Sound frequencies are directly related to the perceived pitch.
What effect causes a siren to change in pitch as it passes by?
doppler effect
What is the pitch tone?
Pitch tone refers to the perceived frequency of a sound. It is how high or low a sound is perceived to be by the human ear. Sounds with higher frequencies are perceived as higher in pitch, while sounds with lower frequencies are perceived as lower in pitch.
What is the name of the effect the causes the pitch of an ambulance siren to change as it passes you?
The Doppler effect
The change in frequency of sound waves in the Doppler effect is heard as a change in?
Whenever the frequency of a sound wave changes, regardless of what caused it to change, the change is perceived as a change in the pitch of the sound.
How can you change sound pitch?
Pitch represents the perceived fundamental frequency of a sound. It is one of the three major auditory attributes of sounds along with loudness and timbre.
Does visible light waves have pitch?
no You might say that, even though nobody else ever does. A change in the frequency of sound is perceived as a different 'pitch'. A change in the frequency of light is perceived as a different 'color'. In each case, even a small change in frequency is easily perceptible to the human sensory system. Who cares what word you use to describe it !
Is the perceived frequency of a sound wave?
Pitch
