Dampening field

A dampening field was an energy field that can disrupt the power emissions to various devices, such as transporters or weapons, within a given area.

During the Second Federation-Klingon War, the Klingons used energy dampeners to disable Federation phasers and then engaged Starfleet forces with their bladed weapons, which gave the Klingons a edge due to their natural strength and toughness as well as the skill in that type of combat.

The use of dampening fields led Starfleet to design the TR-116, which due to its design was not susceptible to dampening fields. (: "A Dreadful Operation")

During the Battle of Sol, Ven warriors boarded Earth Spacedock and deployed energy dampeners to hinder the Starfleet defenders.
