Experimental Groups
Control Group (CONT): This is the group where our variables (below) cannot affect the recorders.
- One recorder will have the microphone disabled; an audio cable will be plugged into the microphone jack.
- The recorder will be placed in a Faraday cage to prevent EMR.
- Here we have no sound waves and no EMR.
- Results here would imply that neither sound nor EMR affect the development of EVPs.
Variable groups are the groups that contain the things that we change for the experiment:
- Variable One (VAR 1): This is the condition where just sound waves can affect recorder.
- One recorder will have its microphone unaltered.
- It will be placed in the Faraday cage.
- Here we have sound waves and no EMR.
- Results here imply EVPs are created by sound and not EMR.
- Variable Two (VAR 2): This is the condition where just EMR can affect the recorder.
- One recorder will have the microphone disabled; an audio cable will be plugged into the microphone jack.
- The recorder will be set in the general area of the Faraday cage and not in it.
- Here we have EMR waves and no sound.
- Results here imply EVPs are created by EMR and not sound.
- Variable Three (VAR 3): This is the condition in which most EVPs are collected.
- The recorder will remain unaltered.
- The recorder will be set in the general area of the Faraday cage and not in it.
Which one will have EVPs? I am excited to see what kind of results we receive.
Constants are the factors which remain the same for each repeated trial for all levels of the independent variable.
- Model of recorder.
- Set of EVP questions.
- The settings on each recorder. Our Olympus Recorders were all set at:
- Mic Sensitivity: Conference
- Rec Mode: ST XQ (highest on this model)
- Low Cut Filter: Off
- VCVA: Off
- Noise Cancel: Off
- Noise Filter: Off
- The location. Various locations will be used, however all sites have paranormal investigators claiming to have captured EVPs. Sites that do not have a history of producing EVPs will not be used.
Next time I’ll cover our experimental procedures.
I’m having flash backs to middle school science class. Are you?
