Israel-based Aero-Sentinel has shared with Defence Blog the outcomes of an impartial acoustic take a look at, confirming that its Aerosol G2 drone outperformed main industrial fashions, together with DJI’s Matrice 350 and Autel Alpha, in general noise discount and frequency management.
The goal take a look at was carried out by Galit Environmental Quality Company, an accredited Israeli group specializing in acoustic examinations utilizing skilled NTI-Audio measurement techniques. The analysis occurred on September 28, 2025, and concerned comparative sound measurements at a number of distances and altitudes, from one to eighty meters.
According to the official take a look at report, the Aerosol G2 recorded a noise stage of 74.9 dB at one meter, in comparison with 85.1 dB for the Matrice 350 and 80.3 dB for the Autel Alpha. When extrapolated to a distance of 200 meters, the G2 measured solely 28.9 dB, practically 10 decibels quieter than its closest competitor. At one kilometer, the G2’s acoustic signature dropped to 14.9 dB, making it nearly inaudible underneath discipline circumstances.

The frequency spectrum evaluation additional confirmed the G2’s acoustic benefit, displaying constantly decrease decibel ranges throughout the examined vary—from 100 Hz to 16,000 Hz—notably within the mid-frequency band most noticeable to human listening to.
According to Aero-Sentinel, the G2 drone is engineered to fulfill the calls for of covert surveillance and tactical reconnaissance in contested environments. The system combines 80 minutes of flight endurance with near-silent propulsion, enabling operators to carry out low-altitude missions with out detection. The firm says the drone can attain a spread of as much as 11 kilometers and has already been operated by particular models world wide.
“The G2 platform is designed to offer a brand new stage of acoustic stealth and reliability for tactical missions,” the corporate mentioned. “This makes it perfect for protection and safety forces requiring each endurance and discretion.”
Compact and light-weight, the G2 measures solely 60 centimeters throughout and weighs 3.5 kilograms. It options 4 electrical motors and might carry payloads as much as one kilogram, supporting a wide range of ISR and communication modules. The drone’s most velocity reaches 12 meters per second, and its line-of-sight vary extends to seven kilometers—or practically double when utilizing Aero-Sentinel’s proprietary directional antenna system.
Aero-Sentinel mentioned the G2’s verified acoustic efficiency positions it as one of many quietest tactical drones in its class, providing operators a vital benefit in stealth and survivability throughout delicate operations.
