श्रुतिthat which is heard — Acoustic Early-Warning & Localisation
What if you could hear exactly where a shot or a drone came from — before you ever saw it?
In thick cover you often hear a threat long before you can see it; the hard part is knowing where it is.
The situation
A forward post in close country
Thick bushes hide whatever is out there. A few cheap microphones around the post hear a gunshot and a drone, and within a second they point an arrow: that way, that far. The team takes cover before the next shot.
How it plays out
Step by step
- 01
A sound arrives
A shot, a mortar, a drone or a vehicle makes a noise the microphones pick up.
- 02
It knows what it is
From the sound alone, it says what kind of threat it is.
- 03
It points to it
By comparing when each microphone heard it, it gives a direction and a rough distance.
- 04
You react first
Cover or return fire happens before the threat is even in sight.
The system itself
Under the bonnet
Turns cheap microphone nodes into a passive sensor net that hears the battlefield — detecting and classifying gunshots, drones, mortars and vehicles, then triangulating a bearing and range in real time.
What it means for you
The bottom line
- ▸Hears and names threats by sound
- ▸Points to where they are
- ▸Gives off nothing, so it can't be spotted
- ▸Built from small, cheap microphones
