Phase Contrast Barrier
One of the special characteristics of the Noise.
By shifting between different planes of existence, the Noise have the ability to dampen or negate energy that falls under the normal laws of physics.
According to records of past battles against the Noise there have been instances where they were successfully repelled by attacks that were made in the instant they increased their existence ratio with our world, and also cases where efficiency was disregarded and a constant barrage of attacks were made until they were successfully destroyed. However, it is difficult to say that either of these options can be considered an effective method to deal with the Noise, primarily because they remain an overwhelming threat due to the fact they can reduce the human body to carbon in a matter of seconds.
The most effective way to deal a decisive blow to Noise equipped with the phase contrast barrier is through the use of Division 2's Symphogear System. At the moment of impact, an attack from the Symphogear System will multiply across various worlds and essentially "tune" the Noise, forcibly dragging them into our world and making them susceptible to the normal laws of physics. This effectively nullifies the phase contrast barrier, allowing the Symphogear user to deal direct damage without suffering any negation or reduction.
Currently, only the Symphogear System is capable of nullifying the phase contrast barrier.
The phase contrast barrier is the only thing beyond the present understanding of researchers in foreign countries, however, needless to say, the Sakurai theory has already successfully analyzed this property and remains the most advanced intelligence relating to the Noise.
Other parts of the world deal with the Noise in different ways. Such as in a certain dictatorship, there were rumors that political offenders who had been sentenced to death were forced to face the Noise. In yet another country, they attempted to destroy the Noise by utilizing powerful energy sources to overpower and eliminate their physical presence. Bombing exercises were run for over an hour at a time, which resulted in changes in the topography of nearby mountains. Afterwards, landslides occurred due to subsequent rain. All of this was said to have resulted in serious damage to everything but the Noise.
