An application of harmonic resonance technology, sonic repulsion fields were sonic barriers projected from multiple stationary hubs. Originally used to contain Tiberium fields in Blue zone cities such as London and Munich, they were later repurposed to protect vital military structures from enemy sabotage.
Structures protected by sonic repulsion fields cannot be captured by engineers or demolished by GDI and Nod commandos, though they also cannot be repaired by friendly engineers. Protected structures become much more resistant to damage. The sonic repulsion field will be destroyed if the structure it protects is critically damaged.

Behind the scenes
- Sonic repulsion fields originally appeared in Tiberium Wars as unbuildable structures that contained Tiberium fields in certain Blue zone maps, they were simply known as "Wall Hubs".
