The vulnerability models is a natural property of all objects: the resonance. Grab a glass of wine, a sound created matches the natural resonance of the glass, the resulting effects can break it.
The same principle is applied to components within the drones. Searching Jose Pedro, examined the effects of resonance of a crucial component of a drone, its gyroscope.
The gyroscope maintains the balance of a drone, providing guidance and rotation, allowing micro adjustments that keeps the air. Generally, drones for recreational and commercial use inexpensive gyros which are designed as integrated circuit packages.
In some cases, gyroscopes have been designed to have resonant frequencies that are above the audible spectrum. But others still remain in the audible spectrum, making them vulnerable to interception of a manufactured noise.
