that's due to Doppler effect. its the relative velocity between speed of the 'source and the receiver' and the speed of the sound that causes the effect... its just an illusion.
The change in frequency and pitch of a sound as it moves toward or away from you is known as the Doppler effect. When a sound source approaches, the frequency and pitch appear higher than they actually are. Conversely, when the source moves away, the frequency and pitch appear lower.
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.
The change in pitch of a sound when it moves towards you is known as Doppler effect. When a sound source moves towards you, the waves bunch up, causing a higher frequency and therefore a higher pitch. Conversely, when the source moves away, the waves spread out, resulting in a lower frequency and pitch.
When a sound source approaches you, the pitch of the sound increases due to the Doppler effect. This is because the sound waves are compressed as the source moves towards you, causing the frequency of the waves to increase, which in turn raises the pitch of the sound.
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.

As the source of a sound moves closer to a listener, the frequency of the sound will appear to increase, resulting in a higher pitch. Conversely, as the source moves farther away, the frequency will appear to decrease, resulting in a lower pitch. This phenomenon is known as the Doppler effect.
As a sound source moves closer to a listener, the pitch of the sound will increase. This effect is known as the Doppler effect, where the perceived frequency of a sound wave increases as the source moves towards the listener.
When a sound source moves towards you, the pitch will increase (higher frequency) due to a Doppler shift. Conversely, when a sound source moves away from you, the pitch will decrease (lower frequency). This phenomenon is commonly experienced in everyday situations, such as when a vehicle passes by.
The apparent change in pitch of a moving sound source is called the Doppler effect. It describes how the frequency of the sound waves perceived by an observer changes as the source of the waves moves relative to the observer.
When the source of a sound is moving towards a stationary observer, the pitch of the sound will appear higher (increased frequency). When the source is moving away from the observer, the pitch will appear lower (decreased frequency). This phenomenon is known as the Doppler effect.
As a sound source moves towards a listener, the pitch of the sound increases. This is because the sound waves become compressed and the frequency of the waves perceived by the listener is higher, leading to a higher pitch.
