Because the rate of change in the pressure in the air differs: high pitch has a rapid vibration, low pitch a slow vibration.
Humans can usually hear from a low of 20 Hz (cycles per second) to 20,000 Hz.
I'm so old that I do not hear much above 12,000 Hz any more.

Sound pitch is determined by the frequency of the sound wave. Low-pitched sounds have a lower frequency, with fewer vibrations per second, while high-pitched sounds have a higher frequency with more vibrations per second. The pitch of a sound is perceived by our ears based on the frequency of the sound wave.
Pitch is related to the frequency of a sound wave. High pitch corresponds to high frequency waves, while low pitch corresponds to low frequency waves.
frequency. The pitch of a sound is determined by its frequency, with lower frequencies corresponding to lower pitches. Therefore, a sound with a low pitch will have a low frequency.
A triangle typically produces a high-pitched sound when struck, due to its small size and thin material. The high frequency vibrations create a ringing noise that resonates at a higher pitch compared to larger or denser percussion instruments.
The height and depth of vocal sound is called pitch. It refers to how high or low a sound is perceived to be.
Frequency is the characteristic of sound that is associated with the pitch or tone of the sound. It refers to the number of oscillations per second of a sound wave and is measured in Hertz (Hz).
