Final answer:
In sound, pitch is measured in Hertz (Hz), related to frequency, whereas volume is measured in decibels (dB), indicative of sound's intensity and loudness.
Step-by-step explanation:
In the context of sound, pitch is measured in Hertz (Hz), and volume is measured in decibels (dB). Pitch is related to the frequency of the sound waves and determines how high or low a sound is. The higher the frequency, the higher the pitch. Volume, or loudness, refers to the amplitude of the sound waves and is quantitatively measured in decibels. Decibels are a logarithmic unit used to express the intensity of sound, reflecting how it is perceived by the human ear. The bel scale, which is the basis for decibels, is named after Alexander Graham Bell.
