sound wave amplifier

[永遠に]

Chinmoku [silence]
Rank: C, B, A, S
Type: Offensive / Ototon Ninjutsu
Range: 0 - 20 meters
Special: Allows the user to temporarily deafen an opponent within the range of the technique. Deafens the user as well at C, B, and A rank.
Description: Chinmoku is a special technique that captures the sound waves of anything within range and redirects it in a concentrated signal, temporarily deafening an opponent and negating his/her use of hearing. After the completed hand seals the user will simply ‘tap’ the device and a deafening siren will envelop the domain. User must give a constant ‘tap’ to the device every post in order to maintain it’s effectiveness. At C rank this technique only has a range of 5 meters and so on until reaching 20 meters at S rank.
Domain: Ototon. Must use with Sound Wave Amplifier.

There's an accepted technique for these weapons already that is a silence effect:

Ten Nai (Dead Spot)
Rank: C, C, C, C, C
Type: Ninjutsu
Range: 5 - 25m
Special: ---
Description: The user snaps their fingers in sync with the activation of their Dosu-Kinuta, resulting in the attenuation of sound in a fixed area expanding in a 360 degree radius from the user's person at all times. In the now 'bubbled' area, the user can choose from a variety of effects, not allowing sound in, not allowing sound out, or a combination of both. For additional C-rank trainings, the user can increase their radius from a base five all the way to twenty-five, granting five meters of influence with each training.
Domain: Must be wearing, Dosu-Kinuta. Ototon Release.

I don't really feel like these techniques are different enough to deserve separate acceptance.

The only difference is that chinmoku temporarily deafens an opponent and can be used in conjunction with genjutsu. But I take your word. I did not see this in the sound wave amplifier index though, its in the sound release sect thats why I didn't find it. You can lock this Lash.
