-Name:Aural Sonar

-User:"The Family of Voyagers"

-Description:Use Aura as a transmitter and receiver array of sound wave.Frequency of sound generated spans from subsonic(1Hz) to ultrasonic(100000Hz).It can transmit almost every kinds of sound and deliver information with enough practise.

-Type:Aural?

-Purpose:Utility

-Auditive cue:Sound transmitted can be heard

-Tier 1:Only allows receving sound with restricted sensitivity.

-Tier 2:Allows transmit and receive of unmoderated sound(Sinus wave only) that cannot deliver infomation via tone.In this tier,using it as sonar for detection purpose become possible because now Aura coating can be turned into a literally sonar array with high sensitivity.But sound imaging is still not possible.

-Tier 3:Sound transmitted can be moderated to deliver information or deceving and be concentrated to used as offensive purpose.Precision and sensitivity of receiver also increased,allowing sound imaging.When facing sound-based attack,Aural Sonar can neutralize them now

-Tier X:With enough practise,Aural Sonar can do literally anything sound can do-even ultrasonic inspection and acoustic cavitation-theoretically,just theoretically.

-Appilcations:Aural Sonar mainly severs as a detection solution:With whole Aura coating becoming a literally sonar array with large aperture,allowing the users to detect objects by echo,even form image of surroundings in darkness or underwater.Highly concentrated sound wave can also tear enemy apart by resonance.

-Limitations:This semblance cannot be turn off,which means the user always have incredible hearing-making them hard to sleep because even the smallest sound can wake them up if they cannot get used to it.In a closed space,echo is highly likely to disorient a novice user.Some usage of Aural Sonar need relevant acoustic knowledge to discover and utilize
