The Audible Spectrum || What we cannot hear

    The topic of my last blog was vision so it is only fair to write about audio. The spectrum of sound is similar to sight except for a few key differences. Unlike popular belief, the speed of light is actually pretty slow. In comparison to sound, light loses the race. Sound can travel through almost all states of matter and materials. The ability of sound is so normal to most that people don't realize that there are plenty of things that we cannot hear. 

    We cannot hear ultrasound or infra sound. Some forms of infra sound can actually make you physically ill. Multiple nations are trying to weaponize the low and high frequencies to make an ultrasonic sound gun. It will effectively knock someone unconscious and they won't hear it coming.

    This Long-Range Acoustics Devise (LARD) is currently in use on the USS Blue Ridge. It is a sonic or ultrasonic weapon. Some versions are used to injure, incapacitate, or kill an opponent. We are still ways away from recreating Saints Row's iconic dub step gun.

The usage of these weapons is no longer science fiction. There is working sound cannons out there. So many other versions of silent but deadly weapons using all kinds of different things. There are microwave guns and rail-guns that harness the powers of kinetic energy that give it the power to level city blocks. While this technology is scary it will give our countries military a huge advantage on defense and offense.
