## How it works

Manage audibility to gather information, evade detection or influence opponents.

## Variants

### Player audibility

<a id="family-22-branch-1"></a>

- Choose a quiet surface or movement method. <a id="family-22-branch-1-variant-1"></a>
- Move while an environmental event masks one's own noise. <a id="family-22-branch-1-variant-2"></a>
- Stay silent as a threat approaches. <a id="family-22-branch-1-variant-3"></a>
- Trade speed for reduced audibility. <a id="family-22-branch-1-variant-4"></a>

### Opponent behavior

<a id="family-22-branch-2"></a>

- Throw or activate a sounding lure. <a id="family-22-branch-2-variant-1"></a>
- Draw an opponent out of an area with sound. <a id="family-22-branch-2-variant-2"></a>
- Imitate a signal the opponent considers safe or familiar. <a id="family-22-branch-2-variant-3"></a>
- Create several sources to confuse a search. <a id="family-22-branch-2-variant-4"></a>

### Information and risk

<a id="family-22-branch-3"></a>

- Reveal oneself through sound to scout. <a id="family-22-branch-3-variant-1"></a>
- Choose signal range according to detection risk. <a id="family-22-branch-3-variant-2"></a>
- Conceal conversation from listening enemies. <a id="family-22-branch-3-variant-3"></a>
- Recognize sound lures used by an opponent. <a id="family-22-branch-3-variant-4"></a>

## Context and limits

A working design-space map: 27 families, 81 branches and 324 variants. Voice control, audio-based play and communication can combine or exist separately. Released-game examples support particular techniques; supplementary combinations are design proposals.
