How do we perceive sound pitch?

Sound pitch is perceived primarily through the frequency of sound waves. Frequency refers to the number of vibrations or cycles per second of a sound wave, measured in hertz (Hz). Higher frequency sound waves result in higher pitch sounds, such as a whistle, whereas lower frequency sound waves produce lower pitch sounds, like a bass drum. This relationship is fundamental to our auditory system, allowing us to differentiate between different musical notes and vocal tones.

In contrast, amplitude relates more to the loudness of the sound rather than pitch, while duration pertains to how long a sound lasts and does not influence how high or low a sound is perceived. Intensity can also refer to loudness, which is connected to amplitude. Therefore, it is the frequency of sound waves that directly correlates with our perception of pitch.
