The Science of Hearing. The human hearing range is between 20 to 20,000 Hz. There is considerable variation. in the hearing range between individuals. Most young people can hear up to 18,000. Hz. Our ability to hear high frequencies declines with age. By the age of 55 some men. can't hear above 5,000 Hz and some women can’t hear above 12,000 Hz. Women tend. to have better hearing than men at high frequencies.
