When it comes to paranormal investigation, few topics spark as much debate as Faraday bags — those metallic pouches designed to block electromagnetic signals. Some investigators swear by them, claiming they eliminate radio interference. Others, however, argue that using one with a spirit box completely defeats the purpose.
Let’s think about this logically.
A spirit box is designed to receive and transmit energy — sweeping through radio frequencies, sound fragments, or digital audio to create a bridge that spirits can use to form words, sounds, and patterns. Whether you believe the communication comes from energy manipulation, environmental influence, or sheer coincidence, the entire premise relies on signals being allowed to flow freely.
So when someone seals a spirit box inside a Faraday bag, what are they really doing?
They’re blocking all radio frequencies.
They’re isolating the device from any electromagnetic energy.
They’re cutting off the very signals that spirits might be trying to manipulate.
In other words — you’ve just placed a gag around a spirit’s mouth.
Imagine inviting someone to speak, handing them a microphone, and then putting that microphone inside a soundproof box. You wouldn’t expect to hear anything, right? That’s what happens when you trap a spirit box inside a Faraday cage or bag.
🔒 What a Faraday Bag Actually Does
A Faraday bag works by creating a conductive enclosure around the device. This blocks external radio waves, Wi-Fi, Bluetooth, cellular data, and other electromagnetic interference. It’s great for digital forensics or preventing hacking — but for spirit communication? It’s the opposite of helpful.
If spirits communicate through subtle electromagnetic shifts, or by influencing radio frequencies, then a Faraday bag doesn’t “filter noise” — it cuts the line entirely.
🧠 Why Some Investigators Still Try It
Some experimenters argue that if a spirit box still produces intelligent responses inside a Faraday bag, then that’s “proof” the voices aren’t coming from radio stations. While that’s an interesting theory, it’s also flawed — because once you block those frequencies, the box can’t sweep them properly. Any sound you hear will likely be electronic bleed, internal circuitry noise, or pre-existing static loops.
You might as well test a radio underwater and call the bubbles a message.
👻 Energy, Not Silence
If we accept that spirits are energetic beings — forms of consciousness interacting through frequency — then they need pathways to transmit and shape that energy. Spirit boxes, white noise, environmental EMF, even our own brainwaves may act as conduits. Restricting those signals doesn’t enhance communication. It silences it.
In short:
A Faraday bag doesn’t filter spirits. It suffocates them.
💬 Final Thought
Next time you’re tempted to “test” your spirit box inside a Faraday cage, remember: spirit communication is about creating opportunities for energy to move — not trapping it. Give the spirits a voice, not a muzzle.
Because every time you block the flow, you’re not disproving the paranormal — you’re just turning down the volume on the conversation.
