The change in frequency is caused by the Doppler Effect
The apparent change in frequency of a sound caused by the motion of either the listener or the source of sound is known as the Doppler effect. If the source is moving towards the listener, the frequency appears higher (higher pitch), and if the source is moving away, the frequency appears lower (lower pitch).
Both. The Doppler effect occurs when there is relative motion between the sound source and the listener. If either the source or the listener is in motion, it will cause a shift in the frequency of the sound waves that are perceived.
The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the wave source. It causes the perceived pitch of a sound to change based on the relative motion between the source of the sound waves and the listener.
No, if the source and receiver are stationary and only the air is moving, there will be no change in the frequency or wavelength of the sound. The Doppler effect occurs when either the source or the receiver (or both) is in motion relative to the medium through which the sound is traveling.
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.

a change in the sound's frequency caused by the motion of the sound's source
The Doppler effect causes a change in sound because of the relative motion between the source of the sound and the observer. When the source is moving towards the observer, the sound waves are compressed, leading to a higher frequency (higher pitch). When the source is moving away, the sound waves are stretched, resulting in a lower frequency (lower pitch).
frequency and pitch would change as the source moves. As the source moves away, the frequency and pitch decrease, and as the source moves closer, they increase. This is due to the Doppler effect, where the relative motion between the source and observer causes a shift in frequency.
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.
The Doppler effect is the change in frequency of sound waves as a sound source or listener moves relative to each other. When a source is moving towards a listener, the frequency appears higher (shorter wavelength) due to compression of waves. When moving away, the frequency seems lower (longer wavelength) due to stretching of waves.
The apparent change in frequency of a sound emitted by a moving object as it passes a stationary observer is called the Doppler effect. This effect causes the perceived frequency of the sound to change depending on the relative motion of the source and the observer – it is higher as the source approaches the observer and lower as it moves away.
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.
