2. Active Noise Control Systems
For drone acoustics control, Active Noise Control (ANC) technology marks a major breakthrough. This complex technology creates anti-noise waves that exactly match and cancel out the sound signature of the drone. To constantly track acoustic emissions, the device uses several microphones positioned deliberately around the drone. Real-time processing of this data by advanced algorithms generates inverse sound waves via specific speakers. Changing flying conditions, wind patterns, and operational parameters allows the technology to adjust and guarantee constant noise reduction in many contexts. Miniaturised electronics have recently advanced such that these techniques may be implemented without appreciably affecting the cargo capacity or flying range of the drone.
