The concept of Binaural Beats was first discovered by Heinrich Wilhelm Dove in the early 1800s(1), when he mounted tuning forks at different frequencies at the end of tubes that went into listeners' ears. The listener perceived a third frequency, which was a difference between the two tones. This concept was mostly just a curiosity until the 1970s, when Dr. Gerald Oster wrote a scientific article that fully outlined the phenonenon(2). In the 50 years that followed, there has been much research on the topic, and this blog outlines the scientific studies which have tested the efficacy of binaural beats on everything from pain management to curing insomnia, making people more focused or relaxed, helping with ADHD, and many more outcomes, depending on the frequencies programmed.
