In situations will the observer perceive the highest frequency from the fire truck siren?

How would the sound reaching you from a fire truck siren be changed if instead of approaching you the fire truck was moving away?

What is the change of pitch when a fire engine moves by you?

As a fire engine approaches, the pitch of its siren will increase due to the Doppler effect, and as it moves away, the pitch will decrease. This change occurs because the sound waves are compressed as the fire engine approaches, making them higher in frequency, and then stretched as it moves away, making them lower in frequency.
