When the source of a sound is moving toward you, the sound waves emitted by the source are compressed, resulting in a higher frequency of the sound you hear. This phenomenon is known as the Doppler effect and is commonly experienced with sirens from emergency vehicles approaching you.
What else can I help you with?
What lets you know that the source of a sound is moving toward or away from you?
When a sound-source moves toward you, its pitch gets higher and the sound gets louder. When it moves away, the pitch lowers and it gets quieter. The frequency change is called the Doppler shift.
Whenever a source of sound moves the frequency heard by the observer is Less than that of the source?
To be more specific, a sound source moving toward you will appear to emit a sound of higher frequency than actual. Conversely, a sound source moving away from you will appear to emit a sound of lower frequency than actual. See "the Doppler effect."
What happens if a source of sound is moving toward you at a high rate of speed?
The waves compress which causes a lower tonal quality.
What happens when the sound source is moving?
When a sound source is moving, it causes a shift in the frequency of the sound waves perceived by an observer. This shift is known as the Doppler effect. If the source is moving towards the observer, the frequency increases and the pitch sounds higher. If the source is moving away, the frequency decreases and the pitch sounds lower.
When you are moving toward a stationary source of a sound its frequency will appear lower than it actually?
As you move toward a stationary source of sound, the frequency of the sound waves will appear higher than they actually are due to the Doppler effect. This effect is caused by the compression of sound waves as you move closer to the source, which increases the perceived frequency.
What happens if the source of a sound is toward you at a high rate of speed?
If the source of a sound is moving towards you, then the pitch of the soundyou hear is higher than the pitch of sound that the source is actually emitting.The rate of speed doesn't matter.BTW ... this also happens if you are moving toward the source.

When a sound source is moving, it causes a shift in the frequency of the sound waves perceived by an observer. This shift is known as the Doppler effect. If the source is moving towards the observer, the frequency increases and the pitch sounds higher. If the source is moving away, the frequency decreases and the pitch sounds lower.
When the source of a sound is moving the sound waves spread out as it travels away from the listener As this happens what does the listener observe?
a lower-pitched sound
When you are moving toward a stationary source of a sound its frequency will appear lower than it actually?
As you move toward a stationary source of sound, the frequency of the sound waves will appear higher than they actually are due to the Doppler effect. This effect is caused by the compression of sound waves as you move closer to the source, which increases the perceived frequency.
What happens when the pitch of a sound seems to changeas the sound source moves toward an observer?
In that situation, what happens is that the pitch of sound seems to change as the sound source moves radially with respect to the observer. When the source approaches the observer, the pitch rises, whereas if the source should recede, then the pitch would fall.
For a stationary observer when the source of a sound is moving it's pitch appears to change?
Yes, that's correct. When a sound source is moving toward an observer, the pitch appears higher (frequency increases) due to compression of sound waves, and when moving away, the pitch appears lower (frequency decreases) due to stretching of sound waves. This effect is known as the Doppler effect.
When the source of a sound is moving its speed incress?
When the source of a sound is moving, the speed of sound waves emitted from the source is not affected by the motion of the source itself. However, the perceived frequency of the sound may change due to the Doppler effect, if the source is moving towards or away from the listener.
What happens to a frequency heard when an observer begins toward the stationary source of a sound?
.The frequency increases
If you are moving toward the source of a sound wave and then pass the source and continue moving away the will change.?
As you move toward the source of a sound wave, the frequency of the sound will appear to increase due to the Doppler effect. Once you pass the source and move away from it, the frequency of the sound will appear to decrease. The change in frequency is a result of the relative motion between you and the sound source.
