Beat Frequency Explained: The Brainwave Driver
The beat frequency is the most important component of binaural beats. It is the mathematical difference between the frequency played in the left ear and the frequency played in the right ear. This specific frequency is what drives the brain into the desired state, such as deep sleep or high focus.
The Formula for Entrainment
The beat frequency is calculated as the absolute difference between the left and right carrier frequencies (e.g., 440Hz - 425Hz = 15Hz). This difference is what the brain perceives. If you want to achieve a state of Alpha (8-14Hz), you must play two tones that differ by that specific amount.
Mapping Frequencies to States
Different frequencies correspond to different brainwave states. Delta waves (0.5-4Hz) are for deep sleep, Theta (4-8Hz) for dreaming or meditation, and Gamma (30-100Hz) for high-level cognitive processing. Binaura supports the full range from Delta to Gamma, allowing for precise control over your mental state.
AI-Powered Frequency Selection
Manually calculating frequencies can be complex. Binaura uses Apple Intelligence to build sessions tailored to your needs. Whether you want a quick nap or a focus session, the AI selects the optimal beat frequencies, ensuring you get the most out of your brainwave entrainment without needing to be a math expert.
