Human ears cannot hear all sounds in the universe. They have a certain range, with an average of 20-20,000 Hz. People's hearing is mainly used to listen to language, and the frequency of language is not wide. Its main range is 500-3000 Hz.

Therefore, scientists call the three representative frequencies of 500 Hz, 1000 Hz, and 2000 Hz speech frequencies. The calculation of hearing is to add the decibels obtained from these three audio tests and divide them by 3. The average obtained is the hearing level of the human ear.
