Investigation Evidence: EVP Protocol
Reducing false positives during Electronic Voice Phenomena (EVP) sessions requires strict environmental control. At First Call Paranormal, we treat audio evidence with a clinical approach to ensure every captured sound is thoroughly vetted for authenticity.
To minimize contamination, follow these technical protocols:
1. Verbal Tagging: If you cough, move, or hear a car outside, tag it immediately by saying it out loud. This saves hours during review and prevents natural sounds from being mistaken for anomalies.
2. Static Placement: Avoid holding the recorder. Hand friction creates "handling noise" that often mimics whispers or movement. Use a tripod or a stable surface to keep the device isolated.
3. Environment Analysis: Identify external noise sources like fans, refrigerators, or electrical panels before you start. These emit EMF interference or rhythmic hums that can distort your recording.
Controlled environments lead to credible evidence. A captured voice is only significant if you can definitively rule out your own team and the surrounding environment.
