“Ever wondered how well playing Call of Duty at maximum volume mimics a real combat experience? Researchers at the Missouri University of Science and Technology must have asked a similar question, because they’ve built a 64-speaker surround-sound audio battlefield designed to train new troops. The system reproduces screaming fighter jets, rumbling tanks, and persistent gunfire — all the better to accommodate recruits to the overwhelming, disorienting cacophony of warfare. Veterans say even with the four large 20-hertz subwoofers, it’s nowhere near the real thing: combat volume is 25 percent louder than the average rock concert, at levels that can cause permanent hearing loss. Still, the creators say every bit of training helps; having near-combat experience is certainly better than none at all. So tell that to your neighbors next time they bang on your wall.”

“You might think that being able to distinguish between a noise associated with danger and a similar but innocuous one would be a useful skill. Yet people find it hard to tell similar sounds apart if one is linked to a bad experience. The finding could help explain how people with post-traumatic stress disorder (PTSD) may become hypersensitive to certain types of sound.

Rony Paz and colleagues from the Weizmann Institute of Science in Rehovot, Israel, repeatedly played one of two tones to volunteers. One group heard a tone followed by an unpleasant smell, the other a tone followed by a pleasant, melon-like odour. The team then tested how well each person could distinguish between the tones they had heard and similar sounds.

On average, those who had heard the sound that was followed by an unpleasant smell performed worse at this task. The effect persisted 24 hours later.
Evolutionary sense

This makes sense from an evolutionary point of view, says Paz. “If you hear a lion and you see a zebra get eaten, that should be enough for you to know that a lion is bad and to avoid it.” If you subsequently hear a different lion, you want your system to respond quickly to the threat rather than try to distinguish between the two lions.

Paz thinks this conditioning may involve rewiring of the amygdala, the part of the brain which controls the fear response. Understanding this mechanism could lead to better treatments for PTSD, he says.”

Someone called doogsgordon on twitter passed me this link to an article about South Korean psyops pumping loud K-pop into North Korea in retaliation for the recent torpedo attack on an S.K battleship. Full story
here

S.Korea recently put up loudspeakers in 11 locations along the tense border to resume broadcasts that had been suspended in 2004. The installation of the loudspeakers amounted to “a direct declaration of a war” and a “flagrant violation” of the inter-Korean declaration for peace and reconciliation signed in 2000, the North’s statement went on.

“Therefore, the revolutionary armed forces of the DPRK will launch an all-out military strike to blow up the group’s means for the psychological warfare,” it said. The North has repeatedly threatened to strike down the loudspeakers if Seoul goes ahead with the broadcasts.
