Military Tries To Cut Through The Noise Of War

Source: NPR July 26, 2017 5:11 AM ET Heard on Morning Edition

U.S. military units have long used technology like night vision goggles to enhance their sense of sight.

Now they’re trying to get a battlefield edge with their ears, too.

The Marine Corps is experimenting with quieted-down weapons and electronic hearing enhancements that could reshape the soundscape of warfare. They want to minimize some sounds and amplify others to get more control over what they and their enemies hear.

About 2,000 Marines have been testing carbines fitted with sound suppressors. The devices have long been used by special operations units, and the Marines want to expand their use into the mainstream infantry.

The primary goal is to reduce the deafening, chaotic roar of firefight noise so that front-line commanders can communicate with their troops.

“The simplest communication is extremely difficult,” said Sgt. Dakota Fox, as he supervised a quartet of young Marines on a Camp Lejeune,

It’s even more of a challenge to communicate in an actual firefight, Fox said, when a dozen Marines or more might be spread across 150 yards, shooting rifles and machine guns at once.

Equipping the weapons with suppressors — cylindrical canisters on the end of the barrel — changes the volume and texture of the sound.

Noise-Induced hearing loss among professional musicians

Source: Journal of Occupational Health
Published November 16, 2016

Objectives:

After presbycusis, noise exposure is considered the second cause of sensorineural hearing loss. Due to exposure to high-intensity sounds, musicians may be at risk of noise-induced hearing loss (NIHL). Given the importance of good hearing in music career, this study aimed to investigate the frequency of hearing loss and use of protective measures among Iranian musicians.

Methods:

In this cross-sectional study, 125 musicians, including 21 women (16.8%) and 104 men (83.2%), with at least five years of work experience were recruited. All participants underwent clinical and audiometric examinations. Demographic data, complaints about hearing loss, and information about the use of protective devices were collected through interviews.

Results:

Audiometric notch in either one or both ears and bilateral hearing loss were present in respectively 42.4% and 19.2% of the participants. The history of tinnitus after performance and ear pain during performance was reported by 64 (51%) and 35 (28%) individuals, respectively. Less than 2% of the participants used hearing protection devices.

Conclusions:

Long-term exposure to loud sounds puts musicians at risk of hearing loss. However, due to their inadequate knowledge, most musicians never use protective devices to prevent damage to their auditory system.

Princess fires starter pistol, Prime Minister suffers hearing loss

(CNN)

Charles Michel, Prime Minister of Belgium, is being treated for an ear injury apparently caused by a starter pistol fired at a Brussels road race.

It was supposed to be one of those routine ceremonial appearances that politicians make all the time.

Show up at a 20K race, wave to the crowd and cheer as the runners bolt from a starting line and dash through the streets of Brussels.  But for Charles Michel, Prime Minister of Belgium, Sunday’s 20 kilometer de Bruxelles event has proven to be a little thorny. Michel says he has been suffering hearing loss since a starter pistol, signaling the beginning of the race, was fired near his left ear.

Surprising cause of death in teen boating accident creates ‘Raven’s Rule’

LAKE WACCAMAW, NC (WECT) –

Investigators originally assumed she’d drowned, but new details have emerged about the tragic death of a Columbus County teenager.

16-year-old Raven Little-White died in August after a boating accident on Lake Waccamaw. The medical examiner’s report lists “drowning” as the probable cause of death, but a toxicology report that came back later revealed Raven had actually succumbed to carbon monoxide poisoning.

The Accident

Raven was on the boat with nine other kids ranging in age from 11-17 on the evening of the accident. District Attorney Jon David said they were not drinking, but just out having fun when they made a fatal error to accommodate the number of people on the inboard ski boat.
