A Lithuanian startup has developed an Android application that allows verified users to monitor for the acoustic signatures of Shahed-type drones used by Russia. The app detects these drones and enables users to report their locations, contributing to a collective defense mechanism. It uses an embedded algorithm to isolate drone sounds from environmental noise and relays detection information to a public map, improving situational awareness. The effectiveness of the system increases with more users running the app. Shahed-type drones are favored in military operations due to their cost-effectiveness. Other nations are also developing countermeasures against drone threats, including microwave drone swarm killers and anti-drone laser systems.
