What creates a binaural beat?
When each ear receives a tone at a slightly different frequency, the listener can perceive a rhythmic beat corresponding to the frequency difference. Stereo separation is therefore central to the classic setup.
Why brainwave bands enter the conversation
Marketing often maps beat frequencies onto named EEG bands such as theta, alpha, beta, or gamma. Those labels describe ranges of measured neural oscillation; they are not simple buttons that guarantee a particular mental state.
What researchers study
Studies have examined cognition, attention, memory, anxiety, pain, and physiological responses. Systematic reviews have reported both promising findings and substantial heterogeneity.
How to evaluate a track
Separate the acoustic technique from the promised outcome. Ask whether the exact outcome has credible evidence, whether the study resembles the product protocol, and whether the claim is about a general technique or a specific recording.
