Opinion Motivated by a desire to help find Malaysia Airlines flight MH370, which is believed to have crashed into the southern Indian Ocean in March 2014, we proposed a way of working out where objects hit the surface of the ocean using underwater acoustic waves. Unfortunately this didn’t lead to finding the plane. However, our research into these waves has moved on since we first proposed the idea in 2017, and we have now been able to identify two locations where the aeroplane could have impacted with the ocean, as well as an alternative route that the plane may have taken. When you drop a pebble in a lake, water waves are generated from the location of the impact, while sound waves create the splashing noise you hear. Another type of wave is generated inside the water too: Hydroacoustic. Similar to a sound wave, hydroacoustic waves move much slower through the denser water than they would through air—1,500 metres per second (m/s), compared to 340m/s. Similarly, when a … [Read more...] about Missing MH370: Mystery Deepens as Sound Waves Suggest Alternative Travel Route—But the Data Is Missing

Metallica launches whiskey ‘shaped’ by sound waves from band’s music
Josh Hafner USA TODAY Published 4:33 p.m. UTC Aug 30, 2018 Heavy metal icon Metallica announced its own whiskey that the band claims is "shaped" by blasting its music directly into the distilled spirit. A former West Point chemistry professor collaborated with the band on the whiskey, called "Blackened," which rolls out to select states this fall. Blaring a playlist of Metallica tracks hand-picked by the band results in "low-hertz sound waves so intense that it actually enhances the molecular interaction" of the whiskey and alters its flavor, the band said in a statement. Much of a new whiskey's success comes down to the story behind it, and Metallica has a good one: Dave Pickerell, the distiller behind the whiskey, is a chemistry engineer who once taught at the military academy in West Point, New York. There, he recalled in a statement, low notes from a massive church organ would reverberate through the halls, the lowest of … [Read more...] about Metallica launches whiskey ‘shaped’ by sound waves from band’s music
Los Gatos doctor charged over sound clips sold for curing disease
By Ethan Baron | [email protected] | Bay Area News Group May 25, 2018 at 2:17 pm Feeling a touch of Ebola? Malaria got you down? Typhoid trouble, again? Or is it something a little less exotic and a lot more common among American folks? Diarrhea, maybe, or back pain? Dr. William Gray of Los Gatos has got you covered, whether you’re suffering from the runs in Atherton or bleeding from the eyeballs in Africa — according to Gray. To be cured, all you need is to do is hand over some cash, open up your ears, and suspend disbelief in an online medical treatment that uses e-mailed 13-second sound clips to fix what ails you. “I’ve done it now for three years and it’s worked on patients all over the world — everything from flu and fever, traveler’s diarrhea, back pain, and even malaria, typhoid, cholera,” Gray said Friday in a phone interview. “There’s a bunch of people in Sierra Leone that have been using it … [Read more...] about Los Gatos doctor charged over sound clips sold for curing disease
What Is a Sonic Attack? Americans in China Warned to Beware ‘Unusual Sounds’ After Embassy Staffer Suffers Brain Injury
World China U.S. Embassy Sonic Attacks The U.S. government issued a warning to all of its citizens in China today, after an embassy staffer reportedly suffered a mild traumatic brain injury resulting from “abnormal sensations of sound and pressure.” The employee, who was stationed in Guangzhou, fell sick and was later diagnosed with a condition that resembled the so-called “sonic attacks” on U.S. diplomats in Cuba last year. “A U.S. government employee in China recently reported subtle and vague, but abnormal, sensations of sound and pressure,” read the government's health alert published on the U.S. embassy in China website Wednesday. “We do not currently know what caused the reported symptoms and we are not aware of any similar situations in China, either inside or outside of the diplomatic community.” Paramilitary police officer guards the entrance to the U.S. embassy in Beijing, China, April 5, … [Read more...] about What Is a Sonic Attack?

The weather phenomenon that made fireworks at TD Ameritrade sound like explosions miles away
Debbie Peffer first thought it was thunder she was hearing at her midtown Omaha home.Then she wondered if there had been an explosion downtown."It kind of scared me for a second," she said. Others in Omaha had similar thoughts Tuesday night, and chatter about the booms buzzed on social media. The noise was fireworks following the Creighton-UNO baseball game at TD Ameritrade Park — but there was something else going on that helps explain why the bangs could be heard miles from the downtown ballpark.People who live more than 3 miles from the stadium — outside the fireworks' typical range — heard the booms around 9:15 p.m. and scratched their heads. Some people even stepped outside and looked skyward for a clue.First, don't blame the fireworks. Bellino Fireworks said the display for Tuesday's roughly 10-minute show wasn't any louder or longer than past ones the Papillion company has put on for Creighton games at TD Ameritrade.Instead, a weather condition … [Read more...] about The weather phenomenon that made fireworks at TD Ameritrade sound like explosions miles away
