the frequency
According to the Doppler effect, the frequency of sound waves will determine the pitch of the sound. The Doppler effect describes the change in frequency or wavelength of a wave in relation to an observer who is moving relative to the source of the wave. In the context of sound, if the source of sound is moving toward an observer, the sound waves will be compressed, leading to a higher frequency and a higher pitch. Conversely, if the source is moving away, the sound waves will be stretched, resulting in a lower frequency and a lower pitch
