The measurement unit for the human hearing audible range is typically expressed in what?

The human hearing audible range is typically expressed in Hertz (Hz), which measures frequency. This unit indicates the number of cycles per second of a sound wave. The standard range of human hearing is generally accepted to be from about 20 Hz to 20,000 Hz (20 kHz). Understanding frequency is crucial in audiology as it pertains to how we perceive different pitches of sounds.

While decibels (dB) measure the intensity or loudness of sound, and Pascals (Pa) measure sound pressure, these units do not directly represent the frequency range of human hearing. Similarly, Watts (W) measure the power of sound rather than its frequency. Thus, Hertz is the correct choice when discussing the range of audible frequencies for humans.
