The traffic in the skies above our cities is changing. Drones are rapidly moving from novelty to necessity — deployed for deliveries, inspections, mapping, and surveillance. Yet with expanding applications comes an increasingly relevant acoustic challenge: How do we manage their acoustic impact in urban environments? In the last week of June, these questions brought researchers, industry representatives, regulatory bodies, and research institutes together at Quiet Drones 2026 in Delft, Netherlands — the fourth edition of the international conference dedicated to all aspects of UAS and UAM acoustics, covering topics from aero-acoustic modelling to community noise perception.

Among the exciting research presented, IHTA’s research contribution is addressing one of the next steps in urban avaiation and drone technology— UAS swarms, where multiple drones operate in a coordinated formation. Though still in the early stage of deployment, swarms hold enormous potential for large-scale applications, and understanding their acoustic impact now is helpful to shape the regulations and design standards of tomorrow. As a first step towards acoustically designing and optimising drone swarms in line with human perception, our postdoctoral researcher Jithin Thilakan presented his work titled „Listening to UAS swarms: exploring the impact of swarm configuration attributes on annoyance perception.“ The study explored how swarm configuration attributes, such as the number of drones, their spatial arrangement, etc., shape annoyance perception, offering early evidence that smarter swarm design could pave the way for environmental friendly drone swarm operations in urban environments. The presented work was carried out as part of the SWOISE project, funded by the LuFo VI-3 programme of the Federal Ministry for Economic Affairs and Energy.
