Why does the pitch of sound increase when a listener move towards a stationary source?

Yes, the frequency is higher - same as if the moving source was towards a stationary person -it is all relative

Would there be a Doppler effect if the source of sound were stationary and the listener in motion?
Yes. The observer would still receive less - or more - wave crests per second.
What is the difference between a mobile source and a stationary source?
Well, a mobile source is a source that is capable of moving. And a stationary source is a source that stays still or doesn't move (or stationary in other words).
When both source and listener move in the same direction with a velocity equal to half the velocity of sound the change in frequency of the sound as detected by the listener is?
If there is no relative velocity between source and listener, there will be no change in frequency.
When For a stationary observer when the source of a sound is moving it is?
C.pitch appears to change -apex
For a stationary observer when the source of a sound is moving its pitch appears to change?
true
When a listener moves towards a stationary source the pitch of sound increase why?
Yes, the frequency is higher - same as if the moving source was towards a stationary person -it is all relative
Why does the frequency of sound waves change for a listener when the sound source moves towards or away from the listener?
This is an example of the Doppler effect. Sound is composed of waves. A particular vibration produces a sound wave with a particular wavelength. When the sound source moves towards a listener the waves are "bunched up". That results in a shorter observed wavelength and thus a higher frequency. When the sound source moves away the opposite happens. The frequency of the sound waves decreases.

What is the perception in the change of a sound's feequency as the source moves?
when the source moves toward stationary observer the frequency increase because wavelength gets shorter.
What is an apparent change 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.

Is it possible to move a source of sound relative to a stationary observer so that there is no shift in the frequency of the sound?
For the sound from a source not to be shift in frequency , the radial velocity of the source to the observer must be zero : that is the source must not be moving towards or away from the observer
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.
