Electronic Voice Phenomena: The Voices Recorded in Silence

Electronic Voice Phenomena, also known as EVP (Fenómeno de Voz Electrónica), is the recording of human voices or sounds of unknown origin on audio recording media. These voices are not audible to the human ear at the moment the session takes place, but are revealed only when playing back the recorded material. The captured words are usually brief, direct, and respond coherently to the questions asked by the researchers.

Manifestation of the phenomenon

The phenomenon occurs through the use of analog or digital recorders, microphones, and frequency receivers. The process of obtaining them consists of precise phases: 1. **Silence or white noise:** The operator activates the recorder in an environment free of external sounds or uses a source of continuous static noise, such as an untuned radio or running water. This background noise serves as acoustic raw material. 2. **Formulating questions:** The researcher asks questions spaced out over time, leaving intervals of silence of several seconds to allow for a response. 3. **Listening and analysis:** Upon playing back the tape or digital file, voices appear that do not correspond to any person physically present at the location. These voices present particular acoustic characteristics that differentiate them from ordinary human speech. They are usually rhythmic, lack natural harmonics, are perceived as whispers or metallic emissions, and are expressed at an altered, accelerated, or slowed-down speed.

History and pioneers

Instrumental communication with the subtle plane began to develop with the invention of the phonograph, but it was consolidated in the mid-20th century thanks to magnetic tape technology. The pioneer of the field was the Swedish film producer Friedrich Jürgenson. In 1959, while recording birdsong in a Swedish forest, he discovered upon playing back the tape a female voice that identified itself as his deceased mother, calling him by his childhood nickname. Jürgenson dedicated the rest of his life to studying the phenomenon and published the book *Voices from Space* in 1964. The Latvian psychologist and philosopher Konstantīns Raudive continued and systematized Jürgenson's work. Raudive recorded more than one hundred thousand voices under strict laboratory conditions, using soundproof chambers and Faraday cages to prevent radio interference. He classified EVPs into three categories according to their clarity and volume, laying the methodological foundations for the investigation of these manifestations.

Famous cases

* **The experiment of Fathers Gemelli and Ernetti (Italy, 1952):** While recording Gregorian chants in the laboratory of the Catholic University of Milan, the wire of the magnetophone kept breaking. Father Agostino Gemelli cried out, asking his deceased father for help. Upon playing back the tape, they heard his father's voice saying, "Of course I will help you, I am always with you." The event was presented to Pope Pius XII, who determined that the finding was a scientific fact unrelated to magic. * **The Hampton Court Palace recordings (England, 2001):** Researchers from the University of Hertfordshire conducted a study in the areas of this historic palace associated with apparitions. Audio devices recorded muffled voices and screams that coincided with abrupt temperature variations in the Haunted Gallery, where tradition places the laments of Queen Catherine Howard. * **The case of Konstantīns Raudive and "Kosti" (Germany, 1965):** During his early investigations directed by Jürgenson, Raudive recorded a very clear female voice repeating in Latvian, "Kosti, my son." Raudive immediately recognized the timbre and idiom of his deceased mother, which led him to abandon academic psychology to dedicate himself entirely to instrumental transcommunication.

Explanations of the phenomenon

For parapsychology and Spiritist doctrine, EVPs are manifestations of disembodied spirits that use the remaining energy of the environment and the electromagnetic noise of the recorder to modulate sound waves. Decarnate entities take advantage of white noise to give it physical form and imprint their messages on the technological medium. Another esoteric explanation proposes telergy, where the operator's own mind projects their unconscious psychic energy and records their thoughts directly onto the tape. Academic science and psychology explain the phenomenon through auditory pareidolia. This is a cognitive process by which the human brain interprets random noises, radio static, or environmental interference as meaningful words and phrases. Likewise, physics attributes EVPs to interference from the propagation of radio waves from distant stations, which are accidentally picked up by the internal circuits of recording devices.

Connections

EVP is integrated within Instrumental Transcommunication (ITC), a discipline that also encompasses psychoimages (the appearance of faces on screens without a signal) and phone calls from the beyond. It is closely linked to physical mediumship, the poltergeist phenomenon, and ghost apparitions, where audio recordings serve to confirm the active presence of an entity in a given location.
