What is the typical range of human hearing in Hertz?

The typical range of human hearing is widely recognized as spanning from 20 Hz to 20,000 Hz. This range encompasses sounds that are considered low frequency, such as bass notes, to high frequency sounds, like those made by birds or certain musical instruments.

This range is significant because it reflects the frequencies that humans, particularly in good health, can hear under normal conditions. Sounds below 20 Hz are considered infrasonic and are generally not audible, while sounds above 20,000 Hz fall into the ultrasonic range, which is also beyond the hearing capacity of most humans.

The other ranges provided do not encompass the full auditory capabilities of the human ear. A lower range like 100 to 10,000 Hz excludes many low and high-frequency sounds that can be important for communication and environmental awareness. Similarly, 40 to 18,000 Hz, and 10 to 12,000 Hz, are also limited ranges that do not fully reflect the complete range of human hearing. Thus, the answer of 20 to 20,000 Hz accurately represents the overall range of frequencies that most people can perceive.
