The Differences between a Spirit Box and an EVP

How a Spirit Box Works

A Spirit Box, also known as a Ghost Box, is a device used for contacting spirits through the use of radio frequency sweeps.  A spirit box can be set to scan either an AM or FM band at a rapid rate of speed. The spirit, or ghost, will manipulate the energy of these audio fragments to form words to answer questions that can either be heard clearly or when the operator takes their audio recording of the session and listens carefully for replies to questions asked. This process is pain-staking and can be time consuming. However, for the avid spirit box operator, it’s highly exhilarating when accurate responses are detected.

The notion of using radio frequencies to enable spirits to speak is nothing new. There have been numerous pioneers in the spirit communication realm beginning with the inventor, Thomas Edison, just prior to his death.

I was a skeptic when I first saw a spirit box demonstrated on a TV show. I bought one out of curiosity and immediately became a fan for life. In my very first session, spirit voices coming through answered my questions and I knew it couldn’t be a CB radio or radio station supplying answers. It was impossible for them to transmit back to me as I didn’t have a shortwave radio receiver.

I primarily use a PSB-7 Spirit box, but there are others available. I even managed to hack a few radios to sweep stations like to 12-589 Radio Shack radio and the DT 200x. Unfortunately, hackable radios are hard to come by now as manufacturers have virtually made them unhackable.

Many Spirit Box responses and EVPs, are not “noticeable in real time. However, some responses can be heard quite clearly while recording.


The PSB-7 Spirit Box Was Invented by Gary Galka
When his daughter tragically died, he wanted a way to communicate with her.

I’ve recorded far more Spirit Box recordings than EVPs as I primarily use a Spirit Box while investigating.

However, I ‘ve also captured several excellent EVPs.

When Spirit Communication Enthusiasts Began to Alter Radios

The first Ghost Box Hack was created by Frank Sumpton in the 1990’s. Sumpton (now deceased) was inspired by a 1995 Popular Electronics article on spirit communication.  He began experimenting with EVP-Maker software. Sumpton soon invented “Frank’s Box” was the first Ghost Box hack. This radio utilized a rewired AM radio.  Others soon followed with their own version of a spirit box. The most notable, are Andy’s Box and the PSB-7 Spirit Box which is the one I mainly use.

What an  EVP Is


EVP stands for Electronic Voice Phenomena; voices caught on recording devices such as tape recorders or digital recorders. EVPs are spirits voices are recorded on electrical or digital equipment outside of the range of the human auditory faculty. Most electronic or digital recording devices are wonderful for capturing EVP’s because they have the sensitivity to record sounds outside of the range of human hearing—just as dogs can hear sounds humans cannot.

Just about any kind of digital recorder works.
Important! Get the kind of recorder that you can transfer audio files to a computer or another device that can hold an audio editing program.

Electronic Voice Phenomena was the first form of spirit voice capture. EVP practically became a household name for ghost hunters due to the many ghost hunting shows that exploded onto the scene in the last decade.

EVP’s can be recorded on any type of audio recording device. What many don’t realize is that several pioneers for attempting to catch ghosts speak started with Thomas Edison. Well into the 20th century, other forerunners included Attila von Szalay, Freidrich Jurgenson, and Tom and Lisa Butler.

EVP’s do not require additional energy known as white noise to record voices from beyond the grave. However, EVPs, unlike ghost boxes are more elusive to capture. Some EVP’s can be quite clear but many sound like soft far-away voices or as hoarse whispers.

Classifications of EVPs.

EVP are ghostly voices recorded from, typically a haunted environment and are not usually audibly heard during the EVP recording session. It’s important to understand that there are different qualities of ghost voices. Therefore, an EVP classification scale system becomes important.

AA-EVP Classifications

Sarah Estep, founder of AA-EVP, created the Estep EVP Classification Scale. In Sarah’s model, there are 3 categories of EVP as a grading standard. This is probably the most used classification used by ghost investigators.

Classification A EVP: “A clear and distinct voice or sound that is universally accepted and undisputed, because it must be understood by anyone with normal hearing and without being told or prompted to what is being said or heard. It can be heard without the use of headphones.”

Classification B EVP: “A voice or sound that is distinct and fairly loud. This class of voice is more common and can be heard by most people after being told what to listen for. It is usually audible to experienced persons who have learned the skill of listening to EVP. It can sometimes be heard without the use of headphones.”

Classification C EVP: “A faint and whispery voice or sound that can barely be heard and is sometimes indecipherable and unintelligible. It may have paranormal characteristics, such as a mechanical sound. Most investigators would apply objectivity and disregard it, but may save it for reference purposes.”
