Sound Sense PRO - Stealth AI: Sound Propagation, Player & NPC Hearing Simulation

Sound Sense PRO – Sound Propagation & Hearing Simulation for Stealth.

Summary. Sound Sense PRO simulates how sound travels through a level: distance falloff, occlusion by materials, and transmission through openings (windows, doors). NPCs (or any actors) can “hear” sounds via a receiver component and react based on intensity and path. Works for single-player and multiplayer (server-side in MP).

👑Key Features:

• Sound Sense View
  Visualizes wavefronts and a sound thread to the source. Color and vibration indicate distance/intensity. If the direct path is blocked, a curved thread shows the actual route.

• Per-Sound Intensity & Thresholds
  Set how far each sound can travel. Material absorption is applied for walls and obstacles. Guards/NPCs can be configured to react only to loud enough sounds.

• Receivers on Any Actor
  Add a lightweight sound receiver component to pawns or actors to detect sources and trigger your gameplay logic.

• Occlusion & Openings
  Handles blocked lines and open paths (windows, doors, vents). NPCs can estimate not only that “a sound came” but also a plausible origin (e.g., an open window).

• Single-Player & Multiplayer
  Efficient in SP. In MP, calculations run server-side for consistent behavior and sync.

• Integration
  Complements 🔗NPC Eyes Sight System - PRO for stealth scenarios that combine light/shadow visibility with sound awareness.
