Sound Suppression Test Unleashes A Flood
“A roar resounded from one of the Space Shuttle launch pads May 7 as 350,000 gallons of water rushed across the Mobile Launcher Platform (MLP).
The torrent of water was released during a test of the water sound suppression system at Kennedy Space Center’s Launch Pad 39A.”
Can Sound Or Silence Be Used To Kill?
“U.S. forces are said to have blasted Van Halen music at Manuel Noriega before the ousted Panamanian leader surrendered to them in 1990. In “Zero Dark Thirty” and the Showtime series “Homeland,” death metal is used to coerce confessions. But can sound or silence be used not just to annoy but also to kill?”
How Does Sound In Air Differ From Sound In Water?
“Sound in water and sound in air are both waves that move similarly and can be characterized the same way. Sound waves can travel through any substance, including gases (such as air), liquids (such as water), and solids (such as the seafloor). Did you know that sound cannot exist if it doesn’t have something to travel through? For example, sound cannot travel through outer space because it is a vacuum that contains nothing to carry sound.”
