“So - What Is Brainwave Entrainment?”

Let’s explain entrainment with a simple physics experiment.

Strike one tuning fork, and holding a second next to it. The second will start vibrating at the exact same frequency.

This is a wonderful phenomenon in the world of science, and it's known as the Frequency Follow Response (FFR), or entrainment.

The same thing happens with the brain. If you expose a frequency to your brain - through one of your senses - your brain would naturally follow that frequency. In turn, that would induce the state of mind associated with that particular frequency.

So, expose it to a gradual 2 Hz frequency and you'll find yourself gently falling asleep.

So how can you do that? How can you expose the brain to a particular frequency?

One method is to use light. By flashing light at a precise frequency (ie, pulses per second), you can influence brainwaves and bring about brainwave entrainment.

Ptolemy was the first to discover this, quite by accident, way back in 200 AD. He found that flickering sunlight on a spinning spoked wheel produced feelings of euphoria.

In the early 1900s, French psychologist Pierre Janet also used flickering lights to reduce patient hysteria, and to induce relaxation.

Brainwave entrainment using light continued to gain strength through the years, and remains popular today, with a plethora of light machines on the market.

But another, even more exciting way to entrain your brainwave patterns was later uncovered: by using audio.

And this is where things really get exciting - all thanks to something a Prussian scientist figured out, way back in 1839.
