What are Isochronic tones?

Isochronic tones are tones that affect your brainwaves when you hear them. When your brain hears these tones it excites a part of your brain known as the thalamus. Once the thalamus is excited, your brain tries to duplicate the frequencies of the Isochronic tones. This is what changes your brainwaves and thought patterns and leads to brainwave entrainment.

Isochronic Tones

Isochronic tones are evenly spaced and turn on and off quickly. They differ from binaural beats in that they do not rely on the combination of two tones. The beat is created external to he person whereas in binaural beats the “beat” is created in your head. Both iscochronic tones and binaural beats are most effective using headphones

Isochronic tones are similar to binaural beats in that they both are forms of brainwave entrainment. They both produce a certain frequency that your brain synchronizes to. The main difference is that binaural beats produce the frequency inside your head while Isochronic Tones produce the frequency outside your head. This is why headphones are always required for binaural beats but not for isochronic tones. In theory you can listen to isochronic tones on a regular pair of speakers however we at Sleepora recommend that you listen to isochronic tones on headphones to get the best effects. Reason being while headphones are not required for isochronic tones, they tend to produce best results because the tones tend to have less external stimuli to compete against.

How do isochronic tones work?

An isochronic tone is a single tone that turns on and off in a particular pattern. It is very effective because during the pauses there is no sound at all.

So, the contrast between on and off is very high, inducing high neural response. In comparison with the binaural beats, where you hear a continuous sound that fluctuates in volume, in isochronics you hear a sound in specific time intervals.

Both binaural beats and isochronic tones are very effective in changing your brainwaves. Research tends to suggest that isochronic tones alter your brainwaves slightly faster than binaural beats however binaural beats are often used more at the Delta level.

Isochronic tones work by emitting sound at regular intervals. This excites the thalmus and causes the brain to duplicate the frequency of the isochronic tones thus changing the brainwave level.

The thalamus is the part of the brain which has a number of functions. These include the regulation of alertness, conscious and sleep.

Sleepora uses both binaural beats and isochronic tones in its program. These form the bespoke developed brain entrainment part of our program. The brain entrainment elements  are mapped with certain times of the day and bespoke insomnia exercises to maximize their effectiveness.

As well as helping people getting better sleep here are just some of the other purposes for which people use isochronic tones:

  • Memory improvement
  • Enhanced creativity
  • Anxiety reduction
  • Increasing energy
  • Endorphin release
  • Increasing motivation
