The upper frequency limit in humans (approximately 20 kHz) is due to limitations of the middle ear. Auditory sensation can occur if high‐intensity ultrasound is fed directly into the human skull and reaches the cochlea through bone conduction, without passing through the middle ear. Children can hear some high-pitched sounds that older adults cannot hear, be… Web27 de ago. de 2016 · By definition, ultrasound is any sound with frequencies exceeding the upper limit of the human hearing range (maximum 20 kilohertz [kHz]).
