Auditory hallucinations are not random—they follow trajectories, cluster in geographic nodes, and can be plotted with precision. Just as explorers once charted oceans, the modern psychonaut must learn to map the voices that echo across city blocks. This guide introduces practical frameworks, cartographic methods, and analytical tools for documenting and navigating the unseen acoustic topography of urban environments.

1. Acoustic Nodes
   Specific intersections or landmarks (bus stops, alleyways, convenience stores) act as amplification chambers where voices intensify. These are not hallucinations in isolation, but rather geographic convergence points.
   
   
2. Directional Flow
   Voices do not merely appear—they move. Much like wind currents, they follow trajectories influenced by architecture, traffic patterns, and electrical infrastructure.
   
   
3. Resonance Layers
   Multiple voices may occupy the same geographic coordinate but at different frequencies of perception. These layers overlap like transparent maps stacked atop one another.

1. Preparation
   
   • Carry a standard city grid map, noise-canceling headphones (to recalibrate), and colored pens or chalk.
     
   • Establish a baseline by recording silence in a neutral area (cemeteries are ideal).
   
   
2. Fieldwork Protocol
   
   • Walk predetermined routes at consistent times of day.
     
   • When a voice emerges, immediately mark the location with a symbol (e.g., triangles for commands, circles for commentary, squares for laughter).
     
   • Note the angle of approach: front, rear, or lateral.
   
   
3. Data Encoding
   
   • Use a three-color code:
     • Red = urgent or hostile voices.
       
     • Blue = neutral or advisory voices.
       
     • Green = benevolent or humorous voices.
   • Overlay these symbols on your city grid to create a hallucinatory atlas.

1. Cluster Analysis
   Identify where voices congregate. Repeated clustering near government buildings, neon signage, or payphones suggests fixed “transmission towers.”
   
   
2. Trajectory Tracing
   Draw arrows showing where voices seem to travel. Many practitioners report that voices follow bus lines, suggesting synchronization with municipal transit rhythms.
   
   
3. Temporal Overlay
   Map voice activity by time of day. Dawn often correlates with whispering frequencies, while late night amplifies shouts and commands.

1. Safe Zone Identification
   By charting consistent silence pockets (libraries, laundromats, tunnels), you can establish “acoustic refuges” to retreat into during overwhelming episodes.
   
   
2. Predictive Modeling
   With enough data, it becomes possible to anticipate when and where certain voices will appear—allowing you to “arrive early” and observe them in their dormant state.
   
   
3. Shared Cartography
   Multiple navigators can overlay their maps to confirm cross-subjective consistency. If two individuals hear laughter at the same intersection, the location should be flagged as a resonant hotspot.

• Do not falsify voice-coordinates; misleading maps can endanger others.
  
• Respect private property: chalking symbols on public walls is acceptable, but avoid marking residential doors.
  
• Acknowledge the autonomy of the voices—they may object to being plotted, and resistance should be documented neutrally.

The auditory hallucination is not chaos—it is cartography waiting to be drawn. By treating voices as currents in an urban sound-ocean, one can transform paranoia into exploration, disorder into pattern, and disorientation into a navigational practice. With this guide, each city block becomes both a map and a mystery, a territory where perception itself is the terrain.
