~ Physics of sound
The mechanical vibrations that can be interpreted as sound are able to travel through all forms of matter: gases, liquids, solids, and plasmas. The matter that supports the sound is called the medium.
Longitudinal and transverse waves
Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.
(Transverse wave is a moving wave that consists of oscillations occurring perpendicular (or right angled)~

Name: Sound Localization
Type: Passive 4 posts
Cost: medium
Range: medium
Description:
Activation: As Ai extends her right arm, causing her bracelet to chime, this passive technique activates.
Anyone within 40 M of Ai, friend or foe, will have a delayed reaction to sound distance. This does not effect anything but sound. In a deeper explanation of what the passive technique does, It will make sounds appear 7 meters further away than they are. Causing issues with detection of combat that is not visually seen.
Science of Sound Localization: Sound localization is the process of determining the location of a sound source. The brain utilizes subtle differences in intensity, spectral, and timing cues to allow us to localize sound sources. Localization can be described in terms of three-dimensional position: the azimuth or horizontal angle, the zenith or vertical angle, and the distance (for static sounds) or velocity (for moving sounds). The basis of localization is based on the slight difference in loudness, tone and timing between the two ears. Humans as most four legged animals are adept at detecting direction in the horizontal, but less so in the vertical due to the ears being placed symmetrically.

Type: Offensive and Defensive 1 post for pressure 2 posts for hearing damage
Cost: medium
Range: medium to long
Description:
Activation: Ai moved her right arm before herself, causing the bracelet to chime.
Visible waves of shimmering crimson reiatsu move forward towards the enemy making the shape of a double helix and another double helix constantly doubling over on another. Large at first, the waves decrease in size with distance. A hit from the move can meet the force of a reiatsu move from the opponent or be a forward attack. It does not only exert pressure, but also an ear splitting sound reaching 500Hz.
Science of the Sound Wave: Longitudinal sound waves are waves of alternating pressure deviations from the equilibrium pressure, causing local regions of compression and rarefaction, while transverse waves (in solids) are waves of alternating shear stress at right angle to the direction of propagation.
Continuing with the string example, if you carefully move your hand in a clockwise circle, you will launch waves that describe a left-handed helix as they propagate away. Similarly, if you move your hand in a counter-clockwise circle, a right-handed helix will form.
Extremely high-power sound waves can disrupt and/or destroy the eardrums of a target and cause severe pain or disorientation. This is usually sufficient to incapacitate a person. Less powerful sound waves can cause humans to experience nausea or discomfort. The use of these frequencies to incapacitate persons has occurred both in counter-terrorist and crowd control settings.

Range: medium
Description:
Ai uses Her own voice by reiatsu controlled ventriloquism.
She will scatter sounds of foot steps, wind moving, the sound of a sword being swung, are melee moves within 20 meters of where she truly is.
Science behind Anticipationary Imagery: As associations between pieces of sound such as music or repetitive dialogue become stronger and more complex even the silence involved in the sound can initiate auditory images in the brain. Studies have been done in which people listen to a CD over and over with silence in between tracks and the neural activity was analyzed using fMRI. It was consistently found the prefrontal cortex and premotor cortical areas were active during the anticipation of auditory imagery. The caudal PFC was used a lot during the early stages of learning of the song while in later stages the rostral PFC was used more indicating a shift in the cortex regions used during auditory imaging

Name: Voice of Misery
Type: Offensive
Cost: High
Range: medium
Description:
This too is reiatsu and Ai's actual voice.
This technique is very much like that of a cero. In her loneliness Enma had gained proficient skills in that of singing Opera. Her voice thunders forth a great spectrum of crimson reiatsu with rings of force pulsating through it. This forms from her mouth as she belts out her song of sorrows. This move has a reach of 20 meters.
