Electronic Voice Phenomenon is the strange appearance of disembodied human voices in audio recordings, but how do these sounds end up in those recorded EVPs.

In a recent episode of 'The Entering The Unknown Show', EVP expert Eamonn Vann-Harris talked about a link between the illusive concept of scalar waves and the voices of spirits that communicate via electronic devices.

The first radio transmission had been made in 1895 and within a decade the possibility that radio-based equipment could be used to contact the dead was being explored.

The Team investigate Tutbury castle, Short clip of our sessions we conducted live at Tutbury castle, Here we are using a rare device name the RT-EVP, this scans the radio frequencies very fast and as you do you can record the sessions and ask your questions. We have used the feature where you can not hear the replies in real time, so our questions were not influenced by what we thought we was hearing at the time, Which to me makes what is being relayed back in this video very interesting indeed!

Entering the Unknown chat show talks to Eamonn Vann-Harris about how he came about being an EVP specialist and communicating with the spirit world, and him building the Infinity and Pegasus machines.

Electronic Voice Phenomenon (EVP) is one area of paranormal research that can be experimented with at home during the COVID-19 lockdown and without the need to visit a haunted location.

Some paranormal investigators call the Panasonic RR-DR60 IC Recorder "the most effective recorder in the world for capturing EVPs," but it has countless faults.

I attended Barri Ghai's EVP masterclass at a haunted former school in Hitchin, where the television ghost hunter shared tips and tricks on how to capture and analyse spirit voices.

As a paranormal investigator you'll often be required to analyse audio recorded during investigations in order to determine if any spirit voices or audible phenomenon have been captured in the recording.

Eamonn joined the Most Haunted team in 2015 as their resident EVP specialist, which basically means he's very good at capturing recordings of spirit voices using an array of specialist equipment.

This is a test recording made using my GhostArk at the Black Swan Hotel in Devizes, Wiltshire.

This is a Rose, a doll I managed to get hold of which is supposedly haunted. I used the GhostBox’s 'radio sweep' function (also known as a spirit box or ghost box) to try to capture EVP.
