====== Noise ======

**Noise** made by [[:agents:]] can be heard by nearby [[:guards:]], causing them to [[:guard behaviour#investigating|investigate]] the sound. Noise can also be heard by [[:mainframe devices:Sound Bugs]], in which case nearby guards become [[:guard behaviour#alerted]].

===== Hearing =====

All human [[:guards:]] can hear noise; the distance they can hear at depends only on how loud the noise is (i.e.\ the sound radius of whatever caused the noise), in particular different guards do not have different hearing ranges, [[:mainframe devices:Sound Bugs]] likewise. [[:Drones]] have "no hearing" and cannot hear any noise.
