It stays the same.
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.
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.
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.
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.

.The frequency increases
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.
If the source is moving towards you, the pitch of the sound will increase. This is due to the Doppler effect, where the frequency of the sound waves increases as the source moves closer, causing a higher pitch to be perceived.

As a listener moves towards a stationary source of sound, the frequency of the sound waves received by the listener increases. This increase in frequency leads to a higher pitch perceived by the listener. This phenomenon is known as the Doppler effect.
The apparent change in frequency of a sound as the source moves in relation to the listener is known as the Doppler effect. If the source is moving towards the listener, the frequency heard is higher (shifted towards higher frequencies), and if the source is moving away from the listener, the frequency heard is lower (shifted towards lower frequencies).
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.
