Related terms

Pitch: Pitch is the perceptual attribute of sound that allows it to be classified as relatively high or low, closely related to the frequency of the sound wave.

Frequency: Frequency refers to the number of vibrations or cycles a sound wave completes in one second, measured in hertz (Hz), and is a critical determinant of pitch perception.

Auditory Perception: Auditory perception is the process by which the brain interprets and makes sense of sounds, involving mechanisms that contribute to how we perceive pitch, loudness, and timbre.
