What happens to sound waves from an object as it moves towards you

1 answer

As an object moves towards you, the sound waves it produces will have a higher frequency and shorter wavelength. This will result in the sound becoming louder and higher in pitch as the object gets closer to you. Additionally, the sound waves will also reach you more quickly as the object moves closer, resulting in a decrease in the time delay between when the sound is produced and when you hear it. Overall, the sound will become more intense and clearer as the object moves towards you.
