Audible range 20 Hz − 20,000 Hz.
Explanation
The audible range of the average human ear is 20 Hz to 20,000 Hz (20 kHz).
- Sounds below 20 Hz are called infrasound, which humans cannot hear.
- Sounds above 20,000 Hz are called ultrasound, which is also beyond human hearing.
However, as people age, the ability to hear higher frequencies decreases, and most adults may not hear sounds above 15–17 kHz.
