A soldier's phone could be used to reveal the location of enemy troops
It links the handset to a microphone built into their helmet's ear protection
Noise of fired bullets is tracked and used to reveal the assailant's position
Researchers say the technology could be on the battlefield within two years
Locations of enemy snipers shooting at troops may soon be revealed instantly on the smartphones of the ambushed troops.
Cutting-edge audio technology is being developed to use microphones in the ears of the soldiers to track two notable noises from a bullet - supersonic air in front of the bullet and the blast as it leaves the muzzle.
Technology is being developed to use these two sounds to trace the original location and reveal where it was fired from.
The data and location will then be relayed to the handset of the beleaguered troops to help them identify and neutralise the threat.
Audio experts that developed the technology say it builds on existing technology and could be employed on the battlefield in just two years
The modern soldier's helmet has inbuilt ear protection to protect them from the raucous of battle and a communication systems to talk to their comrades, other forces and HQ.
The system consists of microphones and either earmuffs or ear plugs and is known as Tactical Communication and Protective Systems, or TCAPS.
However, they currently are not used to find enemy assailants.
Combat acoustics researcher Dr Sébastien Hengy at the French-German Research Institute of Saint-Louis explained: 'At the beginning of an ambush, the most important thing for soldiers is to know where the shooting is coming from so that they can hide on the right side of a vehicle or at least aim in the right direction - and they need this information very fast.'
So he developed a proof of concept that uses the microphones in a TCAPS system to capture a shooter's acoustic information and transmit this to a soldier's smartphone to display shooter location in real time.
TCAPS have four microphones, two outside the ear canal and two inside it, underneath the hearing protection.
The French prototype has an electronic enhancement that activates to block out loud noises, such as when a soldier fires his or her own weapon.
Revealing the shooter location uses the fact that most modern combat weapons fire bullets at supersonic speeds, creating two acoustic waves.
The first is a supersonic shock wave - similar to that formed in front of a jet at supersonic speeds - that travels in front of the bullet and propagates outward in a cone shape.
The explosion of the bullet in the barrel also creates a muzzle wave which radiates out spherically in all directions.
Dr Hengy said: 'Our system uses the microphone underneath the hearing protection in order to detect the shock and muzzle waves generated by supersonic shots and record the time difference of arrival of the Mach wave between the left and right ear.
'By combining the information sent by all the TCAPS deployed on the field, this gives you the direction of arrival of the waves and thus the direction in which the shooter is.'
The location is then sent via Bluetooth or USB to a soldier's smartphone which uses a data fusion algorithm developed by Dr Hengy to calculate the shooter's position.
He added: 'If it's a smartphone with a good processor, the computation time to get the complete trajectory is about half a second.'
Once the soldier returns fire the location system automatically turns off.
Soldiers in France's Operation Sentinel domestic anti-terror force are already equipped with smartphones.
To date, Dr Hengy has successfully demonstrated the system with microphones mounted ear width apart - about 10 cm - in a field.
The technology is currently being refined including integrating head orientation information from tiny compasses mounted in the hearing protection.
Later this year tests with the system on an artificial head is due to begin and, if all goes well, the technology could be deployed as early as 2021.
The TCAPS technology is being developed in collaboration with French company Cotral.
The TCAPS-based shooter location research was presented at the 177th Meeting of the Acoustical Society of America in Louisville, Kentucky.

Not difficult to build something like this. It's about time they start mass producing them for soldiers. I mentioned this sort of technology in another thread recently.

2019-05-13 at 8:54 PM UTCNo doubt somebody eventually will hack into the smartphones and make the person using the microphone think that the enemy is in a location other than where he's actually at. I mean, it wouldn't be too difficult, to make, say for example US soldiers using this, to fire a mortar on their own troops or allied troops because the hacker made them think that's where the enemy sniper was.
As long as it's connected to smartphones and not stand-alone there's all kinds of ways to monkey around with it. Probably better if it's not even wireless. Raw analog data can reveal the direction of both incoming radio signals and sound waves, so this is interesting stuff. Really only needs to send the information to the speaker in the person's ear, rather than to a smartphone. Having its own microprocessor would pretty much eliminate the risk of a hacker using it against them. -
2019-05-13 at 9:06 PM UTCIndividual squads should just be carrying listening devices that feed all audio data to a local intelligence unit. If the squads are also tracked by location the sound from various squads in the area can be analyzed forensically and as it happens. It's not that hard to write a bit of software that takes these data points along with the distance from each squad to the rest in order to triangulate where enemy fire is coming from.

Then the enemy could trace the signal back to the intel unit and blow it up. -

The old video games had scenes in them where the news had stocks news updates on the hour based on the progress of real-time wars, casualties, loses and wins. It was a really spooky prophecy. -

Every squad has a radio operator already, if we allocate a special set of frequencies to transmit the ambient sounds to the intel center, all they can try to trace are the radio signals. Which is possible i guess, but wouldn't add extra risk since like i said every squad has a radio operator already. Also, i was thinking along the lines of fighting insurgents, not pitting two modern armies against each other. -
2019-05-13 at 11:07 PM UTCBut in reality, the US military can already detect, see and hear a single gunshot from outer space, anywhere on the face of the planet. Everything you see and hear is a lie, to keep the money machines rolling. The "new technology" is just smokescreen. Child's-play. Make people think we're still living in the stone age, and the trillions keep rolling in, and millions more die. The US military already has technology beyond even anyone wildest dreams. The rest is all just smoke and mirrors, to keep you occupied. To keep you distracted. To keep you involved. To keep you dying. To keep making them filthy rich with their power and your money. People have NO IDEA just how evil they really are.

You'd be surprised at what some of these insurgents are capable of. Also, if there's a fixed frequency that isn't being used for the usual communications, then it stands out. Zero in on that and you've got a nice target. -

Can't argue with that. They have some way of seeing through walls without radio frequency. Remote neural monitoring allows them to see through everyone's eyes and hear through their ears.. I'm sure they could solve a lot of unsolved murders if they wanted to, but the technology isn't used for that. It's for VIPs. The elite. Can't reveal it to unimportant people. -

I don't doubt it. I've seen some pretty neat insurgent tactics, and general operational capabilities. Also, i said a set of frequencies, ideally you'd rotate over a few every so often. -

Silencers will only work for subsonic ammo. There's still a 'sonic crack' with hyper sonic ammo. And even if you used a 45 rifle with an integral suppressor, there's still ways of detecting the firing mechanisms and the vibration from the firing pin actually causing the gunpowder to expel the round.
If they can detect johnson nyquist noise, they can detect even the best snipers. -
2019-05-13 at 11:16 PM UTCit will be subsonic and it will use new electrically activated primers. there will be no radio traffic because everyone will be plugged into the router HARD WIRED

The Corporate Complex, along with their slaves in the various governments, buy up cures and lock them away in safes forever. They proactively search for new wondrous inventions and confiscate the equipment and jail or kill the inventor. National security. Rocking the money boat is frowned upon heavily and can be dangerous for your long-term health. They are at least 50 years ahead of published technology, as we speak. Everything you see is completely staged, from start to finish. And now they want to globalize it. One World. One Power. One Order. -
2019-05-14 at 4:54 PM UTCWas going to write more about this but I'll just say it's not really that interesting; same principle as triangulation (which is so prevalent a bunch of US cities use those systems to detect gunfire) but allows it to be performed from only one location as opposed to the standard 3+. How well it works will depend on the quality of the microphones used (specifically sample rate), but I wouldn't put too much stock in it being able to determine more than NSEW. It really just seems like yet another contractor gouging the state to me.
I figure it'd be much more effective and accurate to have all members of the squad carry a microphone each, network them and use them to triangulate the source of gunfire collectively. The more microphones and further apart, the more accurate the detection -
2019-05-14 at 5:51 PM UTCfor this system to work someone have to be out there and taking fire, which is not an ideal solution to counter sniping, granted that its better than nothing.
and generally soldiers already have the ability to tell which way shots are coming from when their taking fire. -

Not as easy as you might imagine. And if all you heard was the sonic crack from a hypersonic round, or it was far enough away, it's much more difficult to localize the sound. The human ear can be surprisingly good at localization of sounds, but technology will always be better at doing this. Even if it was as simple as North South East West like aldra mentioned, that's still useful. But a microprocessor can do a lot more than that. -

whats a hypersonic round ?
its the round that reaches you first before you hear it coming.
so by the time your phone app tells you where the round is coming from, the bullet would already have struck long ago and the sniper would have been long gone to another position.
