What term describes frequency between 20 Hz and 20 kHz?

Explanation:
Frequencies that humans can hear fall roughly between 20 Hz and 20 kHz. Sounds in this range are called audible sound because they are detectable by the average human ear. The lower end around 20 Hz corresponds to very deep, bass-like pitches, while the upper end near 20 kHz covers high-pitched tones. Frequencies below 20 Hz are infrasonic and generally inaudible, while those above 20 kHz are ultrasound and also inaudible to humans. Hypersonic is not the standard term for this range.
