Muninn

Muninn (ムニン) is a type of directional microphone used by the Faith Organization.

Etymology
is one of the ravens that fly around the world to gather information for Odin in Norse Mythology.

Principles
Muninn is an early warning directional microphone in the shape of a parabolic device on a tripod. It can pick up a cough from one kilometer away, but at the same time, it can only pick up sound in a limited angle.

Background
Muninn and its counterpart Huginn were adopted by the Norn's unit after they were tricked by a strobe light tactic, causing them to abandon light-based sensors in favor of microphones.

The Three Sisters who Pull In a God of War
Part of the Norn's maintenance base's defenses while in Madagascar were several Munnin and their counterparts. The 37th used their directional speakers to mask their own sounds to trick them and infiltrate the base.
