Sound Blasts!

I know we have talked about a couple of different topics, but I'd like to tie some of what we have talked about in our articles with a post about infrasound itself. Infrasound is sound we can't hear, or sounds below human hearing. and it can be used naturally(earthquakes, etc.) or by human means. This post will talk a little more on how humans have used it currently and in the past.
A Sound Villian
          We know sound can be deadly if used in the wrong hands. We talked about this a little more in depth here with LRAD. Infrasound itself can be related to many different things even ghosts as described here. To go more in depth of how it can be used for harm lets remember Iron Man the movie, when Obadiah uses a sound device to paralyze people? If you don't remember or want a refresher check out this video for a refresher.

Believe it or not this is a real application of sound devices that can be used. Infrasonic generators can cause negative emotions such as fear, anxiety, or depression, as well as biological symptoms like nausea, vomiting, organ damage, burns, or death—depending on the frequency and power level (Mark Rich). Similar devices have been used in the past and are being made by the U.S., Great Britain, Russian using low frequency sound waves in the development of acoustic weapons. These weapons are mostly being developed as a non-lethal approach to handling violence.

A Sonic Bullet Maybe?
Above is what I imagine a sonic bullet would look like if we could see them, but under normal conditions we can't. Police, military and other forms of security can use sound bullets to incapacitate people without bloodshed and has been used in the case of riot control in more modern times by shooting the sound at the low infrasound frequencies. In fact in 1971 there was a good use of infrasound where they used it for riot control which can be further explained and detailed here. That article also goes further into explanation on some different sound weapons as does this one which I also referenced above. So while fun to learn about sound can be a deadly and scary thing or it can be nice and calming. Definitely better than real bullets though in the way of law enforcement.

Hope you enjoyed this little info session on the details of what we have been talking about.
