Protesting? Take a mask—AND hearing protection!

Been to a protest rally recently? You may have seen a cop car with a 2ft x 2ft box on the roof….What is it? Likely, it’s a long-range acoustical device, or LRAD, that emits an unbearable and ear-damaging signal intended to induce panic and temporary incapacity. First developed for the military, these devices are now in use by police in some cities to “control”/incapacitate protesters. Lynne Peskoe-Yang, in Popular Mechanics‘ weapons column, wrote an excellent summary of the subject that you should read and circulate to your friends and acquaintances.

Along with tear gas, tasers, flash-bang grenades and rubber bullets, LRADs are serious weapons—sonic weapons—that you need to prepare for because damage to your hearing will be permanent.

How damaging are LRADs? They can inflict serious pain, destroy your hearing, and leave you with permanent hearing damage. But police have been told they’re “harmless.” So expect indiscriminate use.

So be sure to wear or carry good earplugs AND earmuffs when you hit the street to join a protest march or rally. Once your hearing is gone, there’s no way to get it back. And the 16 million Americans who have tinnitus and/or hyperacusis can attest that hearing damage can be very, very painful and disabling.

David Sykes chairs several professional organizations in acoustical science: QCI Healthcare Acoustics Project, ANSI Committee S12-WG44, the Rothschild Foundation Task Force on Acoustics, and the FGI Acoustics Committee. He is lead author of “Sound & Vibration 2.0” (Springer, 2012), a contributor to the NAE’s “Technology for a Quieter America” and the GSA’s “Sound Matters,” and co-founded the Laboratory for Advanced Research in Acoustics at Rensselaer Polytech. A graduate of UC-Berkeley with advanced degrees from Cornell, he is a frequent organizer of professional conferences in the U.S., Europe, Asia and the Middle East.

The odd saga of the “sonic attacks” continues

Vice News writes that the U.S. government has pulled out diplomats from a station in Guangzhou, China, “after one official suffered mild traumatic brain injury, sparking fears that U.S. government personnel in China were being targeted using the same methods that forced 24 U.S. officials to flee the Caribbean island in 2017.”

As in the earlier case, there has been no official explanation, instead the authorities issue medical alerts and statements assigning blame to Cuba or Russia or China. Vice News put together a timeline of this very odd 18-month old story.  As Vice notes in one entry from January 2018:

Sen. Marco Rubio, who chaired the U.S. Senate Foreign Relations Subcommittee hearing into the attacks, called the weapon being used “very sophisticated technology that does not exist in the U.S. or anywhere else in the world” — despite no evidence that these weapons exist.

Given the enormous amount of money the U.S. spends on its military and intelligence, how likely is it that no one knows exactly what these phantom “sonic weapons” are or how they operate? It just feels like there’s something missing from this ongoing story, making it hard to accept the conclusion that “sonic weapons” are the source of the “mild traumatic brain injuries,” whatever this means.  Are we being too skeptical or do you agree?
