Is it feasible for drones to become completely silent in the future?
It is technically possible for drones to become completely silent in the future, but it is not likely to be feasible from a practical standpoint. The majority of the noise produced by a drone is caused by the propulsion system, which generates noise as it pushes the drone through the air. In order to eliminate this noise completely, the drone would need to be propelled in a way that does not produce any noise, which is not currently possible with current technology.
There are some efforts underway to develop drones that are quieter than existing models, such as the use of electric propulsion systems or the use of noise-canceling technology. However, these approaches are still limited by the fundamental physics of how drones fly, and it is unlikely that they will be able to completely eliminate the noise produced by a drone.
That being said, it is possible that drones will become significantly quieter in the future as technology continues to advance. There may also be other approaches that are developed in the future that allows for the reduction of noise levels in drones, but it is unlikely that drones will ever be completely silent.
