The idea behind shrouding the tail rotor was initially developed to provide additional safeguards for workers on the ground, but also to protect the tail rotor in forward flight and in complicated operational environments, such as working around high-voltage power lines.

Sound reduction benefits followed after much research and optimization from one generation of the Fenestron to the next.
