What quantity is related to pitch and tone and measured in Hertz (Hz)?

• A. Frequency
• B. Noise Dose
• C. Decibel
• D. Amplitude

Answer: (B)

Pitch and tone come from how fast the sound waves vibrate, which is the frequency. Frequency is measured in hertz (Hz), meaning cycles per second. When the frequency is higher, the pitch sounds higher; when it’s lower, the pitch sounds lower. Hz specifically quantifies this rate of vibration, not how loud a sound is or how strong the vibration is. The other terms relate to different aspects: noise dose involves exposure over time, decibels measure sound level (loudness), and amplitude reflects the size of the vibration but not the pitch. So frequency is the quantity that links to pitch and tone and is measured in Hz.
