In general, what is the frequency range of human hearing?

The frequency range of human hearing is generally accepted to be from 20 Hz to 20,000 Hz (20 kHz). This range encompasses the lower audible limit that is typically felt as a low rumble and the upper limit which corresponds to high-pitched sounds. Most people are most sensitive to frequencies in the range of about 1,000 Hz to 5,000 Hz, where human speech falls, making these frequencies critical for communication. The limits of 20 Hz to 20 kHz allow humans to perceive a wide variety of sounds, which is essential for processing environmental cues, enjoying music, and engaging in conversation.
