Learn the Difference between Ghost Boxes and EVP

What Spirit Boxes Are

The PSB-7 Spirit Box Was Invented by Gary Galka after His Daughter Tragically Died So He He Could Attempt Communication with Her

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.

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. (What are EVPs? See next.)

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 while he happened to be experimenting with EVP Maker software. “Frank’s Box” was the first Ghost Box hack which utilized a rewired AM radio.

Others followed and the most notable models are Andy’s Box and Gary Galka’s PSB-7 Box which is the one I mainly use.

What EVP’s Are

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.

Classes of EVPs

Sarah Estep EVP Classification System:

Founder of AA-EVP, Sarah Estep came up with the following EVP grading system.

CLASS – A:  For an EVP to receive a Class A rating, it must be a very clear voice and everyone that listens to the recording can agree on what is being said by the spirit.  Everyone who hears the voice must come to the same conclusion about what it is saying without being told by another investigator. Additionally, these EVPs do not need to be amplified much or cleared of background noise by using a computer sound editing program but can often be clearly heard right on the recording device. It does not have to be extremely loud but it must be clear on what is being said. The Class A. EVPs are the best voices of the dead captured and are highly coveted. I captured a Class A. EVP which you will hear at the end of Part 2 of my Paradise Valley Cemetery movie in the next lesson.

CLASS – B: An EVP that can be understood and that some people will agree on what is being said will fall into the Class B category of EVP.  These EVPs are often not very loud and might have a lot of background noise affecting the clarity of the EVP. All who listen to a Class B EVP might not understand what spirits are saying and might gently disagree on what the EVP reveals. This class of EVP may need to be amplified using a computer and a sound-editing program before they can be clearly understood. This is the most common class of EVPs captured.

CLASS – C: The Class C EVP will be the least quality of EVPs captured.  It is nearly impossible to understand what is being said even with the help of computer enhancement. These EVPs are often just indiscernible whispers or mumbled words which might even sound robotic. The Voice cannot be understood but the investigator still knows that it is an EVP because of the fact that no one was talking during the recording session and some kind of response might be heard in the background noise. Although considered the lowest classification of EVPs, do not dismiss an EVP like this. Any response from the spirit world is worth something!

Below Are Some Spirit Voice Clips I’ve Gathered Over the Years


Spirit Boxes usually have a loud background noise of the AM or FM sweeps. Some hacked spirit boxes have a continual clicking sound.

Please wear headphones or earbuds to listen for both categories of clips.

Many spirit box responses are replies to specific questions I have asked.

I’m creeping through the 2nd floor hallway of the haunted Vendome Hotel asking if any spirits are present.

A woman answers, “I’m a Spirit”. And then a man says, “Hello?”

Can anyone say hello? Response: “Howdy”

I often ask if any spirits need help.

Does anybody here need help: Response: “Be more specific.”

Not all responses answer my question but STILL seem relevant.

My Spirit Guides tell me to finish my book. Guess I’d better get crackin’!
Response:  “Finish book…”

Can you tell me your name? CAUTION: THIS IS VERY LOUD!  Response: “Brian”

My most treasured spirit box clip ever!

I was just sending general greetings.
Response: “Carol, family”

This little teeny clip is proof of the afterlife to me. It’s the very distinct voice of my recently passed significant other. He was a CPA so the numbers thing makes sense for him answering this.

I’m asking how many spirits are present. Response: “15”

Here I’m asking for a name. It’s the most lengthy spirit box recording I’ve ever gotten. We actually carried on a conversation!

Response: “I’m Bill” and more answers to my questions. LISTEN!!

Here I’m using a Sangean hacked DT200X radio. You will notice in the background there is a clicking sound. This is normal.
I’m asking if a spirit has a message. The  spirit repeats the word “message” back.

Response: “Message!”


EVP’s Captured with a Digital Recorder

Some clips are very faint. Again, please wear your headphones!

At a cemetery I caught a woman’s voice in a strange response to a question. “Make Me?????”


Below are Clips featured from my ghost investigation on the Queen Mary I in Long Beach, CA. I was part of a private ghost tour. Some of the clips were caught while the group was walking down to the very bowels of the ship. I had my recorder on during the long walk down, but didn’t expect to get anything. The other clips were captured by the pool area which is now off limits. 

You will hear others at times but can tell the EVPs as they sound somewhat electronic, like voices far away, or eerie whispers right into my recorder.

Clip of woman on the way down. You’ll hear the footsteps of the group walking. At seven seconds she says,“I can’t.”

Clip of man’s whisper  I got while listening to the tour guide before we head downwards.  At three seconds,“Smoke.”

Often spirits will correct one another–sometimes vehemently. Here’s a clip captured upon immediately arriving in the boiler room area with the group. The group is patiently waiting for the tour guide to begin to speak…

A female spirit says, Sinking!” This is a class A. EVP. Listen to a spirit who immediately replies to her statement  below.

A male spirit replies to the female spirit above who said, “Sinking”. Clip captured in the boiler room area. At seventeen seconds,“She’s not sinking!” 

Towards the end of the investigation, the group was let loose to investigate on our own. In the boiler room I received a very strange EVP. A man says at two seconds,“It’s growing.”


I investigated the Robinson Springs Cemetery in Millbrook, Alabama in 2012 more than once. This cemetery was so old, that it contained many Civil War soldier burials.

While walking around a very old cemetery in Millbrook, Alabama, I was talking to myself mentioning some dates on the old headstones. A male spirit chimes in leaving me a surprise EVP. He’s apparently adding a date to what I am saying. As with most EVP’s, I didn’t hear this until I played back my entire audio recording.

The spirit is adding his own date. He’s saying, “1897 or 1997.” I’ve boosted the volume so you can hear better. I’ve also cleaned up the background noise for the very same clip below.

The same clip where I’ve attempted to reduce the background wind blowing and traffic noise so you can hear better.

In the same investigation, the session above contained another EVP. I entirely missed this until I re-listened to the many recordings for the post. This shows how EVP’s can be missed even after listening to an audio segment many times.

A man whispers, “How about you?” Listen carefully. It goes very fast!
