Nenjutsu: Hearing Alter

Nenjutsu: Hearing Alter is a Nenjutsu technique developed by Meikyou Shisui. By flowing yin chakra into her ears, she is able to heighten their performance and expand the range of sound they can perceive.

Ordinarily the human range of hearing falls between 20 hertz and 20 kilohertz. Kyoumei is able to expand the range of her hearing into the infra and ultrasound ranges, and to vastly increase the sensitivity of her hearing overall. Functionally, this allows her to perform auditory imaging on those around her. This enables her to "see" in fine detail, and to even perceive the flow of blood and positions of internal organs in those near her.

Additionally, she can more accurately sense the positions of bodies in motion in an expansive range around her thanks to the Doppler effect. This radar-like ability allows her to sense the movements of enemies at long distances, and even to telegraph the movements of military forces.
