Breakthrough: An Amazing Experiment in Electronic Communication with the Dead

Konstantin Raudive's Breakthrough is a primary source documenting the author's own experiments in what became known as electronic voice phenomena, purported recordings of voices from the deceased captured through radio static and tape recording. As firsthand testimony it is valuable evidence for how this specific investigative claim originated and spread within parapsychology, and it remains a foundational text cited by EVP researchers. Its scientific standing is weak by any controlled standard: the interpretation of ambiguous audio noise as intelligible speech is highly susceptible to auditory pattern-matching and expectation, and no controlled, blinded replication has established that the phenomenon Raudive described is anything other than that ordinary perceptual effect. Cite it for the history and content of the claim, not as evidence the claim is true.
