Theta Wave Synchronization

This is a replication of a Theta wave entrainment rhythm first created by scientists in the 1960s to lull patients into a deep, colorful, creative dream state. Listen to it for 10 minutes, longer if you can. The longer it plays, the deeper you’ll go. So go.

How It Works

The human brain produces different levels of electrical activity depending on the amount of information it is processing. During a detailed task, it lights up with electrical charges as it sends and receives messages at a high concentration, its neurons firing in quick succession. While in a relaxed state of sleep, it glows dimmer, its neurons firing less often. This brainwave activity is calculated by electroencephalographs (EEGs), machines that gather data from electrodes adhered to the skull and measure the frequency (the amount of electric activity per unit of time) in Hertz. Measurements of electrical activity in the brain are more commonly referred to as brainwaves.

Throughout the day, the brain lingers between four different types of brainwave patterns:

  • Beta (12 -30 Hz): the normal, awake consciousness associated with busy tasks
  • Alpha (8 – 12 Hz): the relaxed and reflective state, like those induced by closing the eyes during waking hours
  • Theta (4 – 7 Hz): a very relaxed state associated with meditation and some sleep states
  • Delta (3 and under Hz): deep, dreamless sleep

Theta waves (at around 4 to 7 Hz) are the sweet spot for many brain functions. There, we often experience extreme relaxation, creativity, as well as vibrant mental imagery. For the past forty years or so scientists have experimented with different audio techniques to induce Theta waves. One technique is to play a specific audio rhythm to replicate the 4 to 8 Hz frequency of the Theta brainwaves. By doing so, scientists hoped to lull the brain into the Theta state on command. Fantastically, it works.
