Re: Bustin My Eardrums to the Emperor's New Groove
The first things that come to my head when I think of making Sound from chakra, is if I wanted to make my own custom Jutsu, how would I do it.
I take a sound that is already there, and either amplify or boost that sound waves/vibrations that are already there by concentrating my chakra into the sound that was made by whatever made it. Everything produces sound, its is simply a matter of whether it is at a decibel that we can hear it or not. For example, an Inuzuka could hear something that a normal ninja, without sound manipulation, would be unable to hear. They wouldnt question whether or not he actually heard anything. It is understood that different animals have a different decibel level of sound that they are capable of hearing.
The same works with if you want to take away sound.......which by what I just said is impossible, so one would concentrate on diminishing the decibel of a certain sound so that a person could not hear the attack or the person themselves. this is no easy feat however, a person would have to explain that they have studied every animal in the narutoverse and explain that they tested their decibel of hearing, allowing them to instantly know what decibel to diminish a certain sound to.
so in closing, the making of chakra in itself produces a sound, evidence by techniques such as chidori, rasengan, rasenshuriken, and many other techniques that have a distinct sound to it. so once we channel our chakra, we concentrate on the sound waves produced from the channelling of the chakra and simply amplify it to our desired result.
there may be more to this, but this is just the way i perceive it.
Edit: I would also like to add that although the decibel is lowered, the sound still occurs, however the eardrum of the animal is incapable of triggering that the sound was made. With this, it is totally capable of having a Silent Sound Genjutsu.
Studying the sound of other objects such as wind, would allow a sound user to manipulate another sound to appear as that of something else, perhaps an animal, music, anything else with a definable sound.
The easiest Sound would probably come from the most noticeable, and that is the voice.
