Which frequency range is considered audible?

Explanation:
Audible sound for humans spans roughly from 20 hertz to 20 kilohertz. Frequencies below 20 Hz are infrasonic and generally can’t be heard, though they may be felt as vibrations. Frequencies above 20 kHz are ultrasonic and also outside typical human hearing. The range from 20 Hz up to 20 kHz therefore represents the full interval people can usually hear, with individual hearing varying by age and health. The other options don’t match this full audible span: one is a smaller subset within the range, and the others refer to frequencies outside what humans typically perceive.
