The commonly stated range of human hearing is 20 to 20,000 Hz.20 to 20,000 Hz corresponds to sound waves in air at 20°C with wavelengths of 17 meters to 1.7 cm (56 ft to 0.7 inch). Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. The human auditory system is most sensitive to frequencies between 2,000 and 5,000 Hz. Individual hearing range varies according to the general condition of a human's ears and nervous system. The range shrinks during life, usually beginning at around age of eight with the upper frequency limit being reduced. Women typically experience a lesser degree of hearing loss than men, with a later onset. Men have approximately 5 to 10 dB greater loss in the upper frequenciesby age 40.

This is due to a lot of social and external factors. For example, more than once, it has been proven that men spend more time in noisy places, and this is associated not only with work, but also with hobbies and other things. But women have a sharper hearing loss after menopause. In women, in contrast to men, hearing decreases and is worse at low and partially medium frequencies. While men are more likely to suffer from hearing loss at high frequencies.
