4. Acoustic Stealth Technology
Through a mix of cutting-edge technologies, this innovative technology renders drones nearly inaudible to human hearing. The device moves drone-generated noise into regions outside human hearing capability using frequency shifting techniques. Acoustic cloaking effects are produced by special acoustic metamaterials guiding and spreading sound waves. Phase-array sound cancelling devices included into the technology produce exact zones of silence surrounding the drone. Modern vibration isolating techniques stop mechanical noise from spreading over the drone's construction. This all-encompassing method of acoustic stealth has produced drones capable of running with an acoustic signature below 20 decibels at operational distances.
