Costs of hearing-related health claims on the rise in Canadian military

Safety and situational awareness cited among reasons to not use hearing protection

The cost of health claims related to hearing loss among members of Canada's military is rising, due in part to the reluctance of members to wear protective equipment and because the most suitable devices aren't always provided.

Explosions, gunfire, engine noise and alarms all contribute to hearing loss among military members. Almost a third of them have chronic hearing problems by the time they retire, according to surveys by Veterans Affairs.

A 2016 study obtained by Radio-Canada looked at how to better protect the hearing of members with pre-existing hearing loss, and found that military personnel were reluctant to wear hearing protection.

Some of the reasons were:

Discomfort.
Incompatibility with other head gear.
The feeling of isolation that comes with sound dampening.

But the biggest reason was that earplugs or whatever other protection device used would impair situational awareness, safety and "interfere with successful completion of the mission," wrote Dr. Sharon Abel, a senior scientist at Defence Research and Development Canada.

That has led to increased health costs for the military. The Canadian Forces Health Services Group spent about $890,000 in 2013-14 on health costs related to hearing loss, followed by $937,000 in 2014-2015. In 2015-16, the last year for which data is available, it was close to $1.1 million.

Different soldiers, different needs

Richard Blanchette, a retired major-general who suffered hearing loss during his years of service, said the Department of National Defence does everything in its power to protect members and it's the responsibility of the members to do their part.

Nobody else can do it for them, he told Radio-Canada.

Different military members, however, have different issues.

Abel's study found while earplugs may reduce the risk of hearing loss for people with normal hearing, they would increase impairment for people with pre-existing hearing loss.

Those people would be better served by more specialized protection, she wrote.

"Insufficient consideration is given to the selection of devices that will support the auditory tasks being carried out or suit the hearing status of the user."

The military has set up an awareness program for its members about hearing loss, said Pierre Lamontagne with Canadian Forces Health Services.

But soldiers remain reluctant to use some of the equipment they may need because it adds to the considerable weight they may already be carrying in the field, he said.

Health consequences

Lamontagne said he makes recommendations to commanders of the units, but it's the commanders who make the purchases.

While about one in five soldiers needs specialized protection for hearing loss, the devices may be purchased based on general rather than individual needs, he said.

The consequences of hearing problems are not always recognized because they are invisible, according to Chantal Laroche, a professor of audiology at the University of Ottawa.

However, the side-effects — persistent ringing in the ear, for example, or an inability to communicate with others — can cause other serious health problems, including mental health issues, she said.

Laroche said that in general, specialized hearing protections can be expensive, but the military should weigh those costs against the amount they are spending on health costs and disability claims.

DND funds new technology at Carleton University that could protect military equipment
DAVID PUGLIESE, OTTAWA CITIZEN A Carleton University research team led by Shulabh Gupta, a professor in the Department of Electronics, has received $1.5 million in funding from the Department of National Defence's Innovation for Defence, Excellence and Security program to create the next generation technology for electronic camouflaging. The project will develop an artificial electromagnetic veil to protect military equipment from enemy detection based on cutting-edge Metamaterial technology, according to a news release from Carleton University. The veil would cover the surface of the military asset and hide it from a range of detection methods operating is various spectral bands, including radio frequencies, infrared and optical. The project, officially known as the Artificially Intelligent Biomimetic Metasurfaces for Electromagnetic Camouflage, is a collaboration with the University of Ottawa and Polytechnique Montreal, Carleton University noted. “In much the same way an octopus dynamically senses and adapts to its background, changing its colour as it moves, these smart electromagnetic veils would be able to sense their backgrounds, even while moving, and in real time adapt to blend into their surroundings while protecting the important targets,” Gupta said in the news release. “While an octopus is only capable of hiding from the optical detection of predators, assets utilizing the new veil would be hidden from a broad range of detection.” For example, radar can detect and distinguish a vehicle driving through a forest because the vehicle reflects a different signal back compared to its background, the university noted. To prevent this, the veil on the vehicle would predict the signal being reflected back by the surrounding trees and mimic it, making the vehicle indistinguishable from the trees as it drove through the forest. https://ottawacitizen.com/news/national/defence-watch/dnd-funds-new-technology-at-carleton-university-that-could-protect-military-equipment

Updated - Dassault makes it official – Rafale is out of Canadian fighter jet competition
DAVID PUGLIESE, OTTAWA CITIZEN Dassault Aviation has officially confirmed to Agence France-Presse that the firm has pulled out of Canada's future fighter program. The company had planned to offer the Rafale but decided against competing the aircraft because of the extensive Canadian requirements for interoperability with U.S. forces, according to a number of news reports, citing sources. The Canadian government confirmed the withdrawal after the news report became public. “On November 8, the French government officially notified Canada of its withdrawal from the competitive process to replace Canada's fighter jet fleet,” said Public Services and Procurement Canada spokesperson Rania Haddad. “We will continue to work closely with the remaining eligible suppliers to ensure they are well positioned to participate in the ongoing competition.” https://ottawacitizen.com/news/national/defence-watch/dassault-makes-it-official-rafale-is-out-of-canadian-competition
