  1. When analyzing audio recordings for EVP (Electronic Voice Phenomena), which frequency range is most commonly associated with captured paranormal voices?

    Answer: 200 Hz–1,500 Hz

    EVP voices most often appear in the 200 Hz–1,500 Hz mid-range, which overlaps human speech frequencies.

  2. A paranormal investigator discovers a cold spot in a room. What is the first scientifically rigorous step before attributing it to paranormal activity?

    Answer: Rule out natural causes such as drafts, vents, or poor insulation

    Debunking natural explanations first is a foundational principle of credible paranormal investigation.

  3. Which type of camera setting is most recommended for capturing potential paranormal activity in near-total darkness?

    Answer: Full-spectrum or infrared with wide aperture

    Full-spectrum and infrared cameras capture light wavelengths invisible to the naked eye, making them ideal for dark environments.

  4. What does the term 'contamination of evidence' mean in a paranormal investigation context?

    Answer: Introduction of non-paranormal factors that can explain or corrupt potential evidence

    Contamination refers to anything mundane—noise, movement, equipment malfunction—that could falsely appear as paranormal evidence.

  5. When using a digital voice recorder for EVP capture, why should investigators avoid whispering?

    Answer: Whispers can be misidentified as EVPs during review

    Whispers are acoustically similar to EVP voices and can be mistakenly logged as paranormal audio evidence.

  6. What is a 'control recorder' used for during a paranormal investigation?

    Answer: A second recorder placed in an uninvestigated room to identify ambient noise sources

    A control recorder captures ambient sounds in an undisturbed area so investigators can compare and isolate true anomalies.

  7. Which of the following is considered a Class A EVP?

    Answer: A clear, distinct voice easily heard and understood without enhancement

    Class A EVPs are the highest quality—clearly audible, intelligible, and require no audio processing to recognize.
