Binaural Beats Explained: How They Work and What They Do
Binaural beats are an innovation in audio technology that works by playing two slightly different frequencies in each ear, thus your brain creates a third 'phantom' frequency, which forms a unique beat. This perceived rhythm is called the binaural beat. This can induce states of relaxation, focus, or creativity, depending on the frequency used.
If you’ve ever explored binaural beats for meditation, focus, or sleep, you may have come across terms like base frequency (also known as carrier frequency), offset frequency, and target frequency. Understanding these three frequency concepts is key to knowing how binaural beats work, and how they can affect your brain.
A binaural beat is an auditory illusion where your brain splits the difference between two similar tones played separately in each ear. In order to understand the science behind binaural beats, we need to study some of the properties of sound waves themselves.
How Binaural Beats Work
A binaural beat occurs when you hear two slightly different sound frequencies, one in each ear. Your brain doesn’t hear both tones separately, it perceives the mathematical difference between them as a rhythmic beat.
Example:
- Left ear: 200 Hz
- Right ear: 205 Hz
- Brain perceives: 5 Hz
- Result: Your brain follows along and is “entrained” to 5 Hz, which corresponds to a theta brainwave state (relaxation and meditation).
Simple, but effective.
Base Frequency vs. Offset Frequency vs. Target Frequency
Binaural beats are created using two related frequencies, and a third frequency is the desired outcome. Here's how it works:
- Base Frequency (Carrier Frequency)
This is the steady, constant tone that plays in one ear (usually the left). It forms the foundation of the sound. “Base frequency” means the same as “carrier frequency.”
Example: 200 Hz
The base frequency does not change, even if the track’s target frequency changes.
- Offset Frequency
This is the other tone played in the opposite ear. It is slightly higher or lower than the base frequency.
Example: Base = 200 Hz, offset = 204 Hz
The difference between the base and offset is the target frequency. In this case, 4 Hz.
Dynamic Tracks
If the track changes frequency at some point, it is the offset frequency that changes while the base remains fixed. The change in frequency should happen gradually, to ensure a smooth progression of the binaural beat.
Example:
- Base: 200 Hz
- Offset starts at 208 Hz → Target frequency = 8 Hz
- Offset gradually decreases to 204 Hz → Target frequency change = 4 Hz
- Target Frequency
This is the mathematical difference between the base and offset frequencies. This is the binaural beat your brain actually perceives. The target frequency determines the brainwave state:
Target Frequency Brainwave Effect
The target frequency determines the brainwave state:
| Target Frequency | Brainwave | Effect |
|---|---|---|
| 0.5-4 Hz | Delta | Deep sleep, restoration |
| 4-8 Hz | Theta | Meditation, calm, intuition |
| 8-12 Hz | Alpha | Relaxation, creativity |
| 12-30 Hz | Beta | Focus, concentration |
| 30-100 Hz | Gamma | High-level cognition, 40 Hz gamma studies |
Static vs. Dynamic Binaural Beats
- Static:
This means that the target frequency remains constant. Both base and offset stay the same.
Example: Base 200 Hz, Offset 204 Hz → Target 4 Hz throughout.
- Dynamic:
Target frequency changes gradually. Base stays fixed, offset changes.
Example: Base 200 Hz, Offset 208 Hz → 204 Hz → 202 Hz, creating a beat that ramps down from 8 Hz → 4 Hz → 2 Hz.
This is useful for tracks that guide the brain through multiple states, e.g., starting relaxed and moving into deep meditation.
Why the Correct Base Frequency Matters
Even though the brain is focussed on binaural beat itself, the base frequency shapes the entire experience.
- Tone: Lower base frequencies are warmer and feel grounding; higher ones are higher pitched and feel more intense
- Ear fatigue: It is important producers choose a pleasant base frequency that harmonizes with the music to avoid listener fatigue.
Optimal Base Frequency Use
There is a table known as the Oster Curve, which loosely shows which base frequency is most effective for producing a perceptible/effective binaural beat at a given target frequency. In other words, it maps a suggested optimal base frequency to use depending on the brainwave frequency you want to achieve. It doesn't have to be followed exactly but it's a good guide.
The curve is the work of Dr. Gerald Oster, a biophysicist who published the landmark 1973 paper “Auditory Beats in the Brain” in Scientific American.
