When a sound source approaches you does it get higher or lower?

Higher. Well, the pitch gets higher. Frequency itself can never change. Pitch is our perception of frequency. The change in pitch due to position is known as the Doppler Effect.

What happens to a sound source as it approaches?
It appears to have a higher frequency due to the Doppler Effect.
When a sound source moves towards you what happens to the wave speed?
It is called the Doppler Effect. When the source of waves approaches you (can be any type of waves - mechanical, electromagnetic like light etc.), the wavelength gets smaller and frequency higher. So when a car approaches you, you hear higher tone than when it departs.
When a source of sound approaches you what do you detect an increase in?
frequency
How does perceived pitch change as a sound passes a listener?
Herr Doppler noted that the pitch is higher as the object approaches and lower as the object departs.
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 is an apparent in frequency of a sound source that moves relative to an observer?
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.

When a sound source approaches the pitch you hear is higher than when the source is not moving?
Yes. This is called a blue shift, and is caused by shortening of the period of waves. It's inverse is a red shift, which occurs when the observer is moving further away from the source of sound. These are both examples of Doppler Shifts.

Which of these statements is falseA lower-pitched sound is produced when the vocal cords are relaxed.A lower-pitched sound has a higher frequency than a high-pitched sound.Stretching the vocal cords produces a high-pitched sound?
A lower-pitched sound has a higher frequency than a high-pitched sound.
What is the difference from lower sound waves and higher sound waves?
Because the low note is short and the high note is hifh
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.
Why does the siren get lower as it gets farther away?
This is due to the Doppler Effect. The Doppler Effect explains how a source of sound, in this case the siren, is catching up with the sound waves it emits. The space between waves is consequently shorter. This produces a higher frequency sound. As the source passes you, it is speeding away from the sound waves. The waves are spread further apart, thus producing a lower frequency.
