Answer – Pitch is a fundamental aspect of sound perception, characterizing the subjective experience of highness or lowness in audio signals.
Explanation:
Pitch is directly linked to the frequency of sound waves, with high-frequency waves corresponding to high-pitched sounds and low-frequency waves generating low-pitched sounds.
A sound wave is composed of vibrations in a medium, such as air, causing pressure variations that propagate through space. The frequency of a sound wave indicates the number of cycles of the repetitive waveform per second, usually measured in Hertz (Hz).
Listeners can perceive differences in pitch as small as 2 Hz, and highly trained musicians can sometimes identify differences down to 0.2 Hz. Pitch plays a critical role in music, enabling listeners to order sounds on a frequency-based scale and distinguish between various instruments and voices. Pitch differs from loudness, which measures the amount of energy carried by the sound waves, thus affecting the perceived volume.
