How is pitch determined in auditory perception?

Pitch in auditory perception is primarily determined by the frequency of the sound wave. Frequency refers to the number of vibrations or cycles of a sound wave that occur in one second, measured in hertz (Hz). Higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

When a sound wave has a high frequency, our auditory system interprets this as a higher pitch; conversely, a sound wave with a low frequency is perceived as a lower pitch. This relationship is fundamental to how we differentiate between various musical notes or sounds, such as distinguishing a high-pitched whistle from a low-pitched drum.

While other factors such as amplitude (which affects loudness), duration, and phase can influence our overall perception of sound, it is frequency that directly relates to the pitch we experience. Thus, the correct understanding of pitch perception centers on the frequency of sound waves.
