Isochronic Tones

Isochronic Tones

It’s night.
A fire is blazing and flickering. There is chanting and drumming…

Imagine a traditional tribe engaged in a ritual.

People are entering into a trance state because of the repetitive rhythmic patterns.

Various tribes all over the planet have, or have had, similar ceremonies, enabling people to reach such states.

Isochronic tones are a modern form of these rituals. The rhythmic pulses of sound induce a certain state in the mind of the listener.

 

 

What are isochronic tones?

Simply said, an isochronic tone is a single tone turned on and off very quickly. And in between every pulse there is silence.

The amount of pulses per second is the frequency. (E.g. 7 hz means there are 7 of these tones per second.)

The pitch (how high or low every pulse is) doesn’t influence this frequency.

Listen here for an example (no headphones are required to hear the isochronic tone – he same tone is fed into each ear):

Isochronic tones are a form of neural entrainment similar to that of binaural beats.

 

Binaural Beats & isochronic tones: difference

For clarity’s sake, I want to add a few words about the difference between binaural  beats and isochronic tones. While the goals can be the same in the two technologies, there is a difference in the actual technology, as well as in the results.

Binaural beats do not produce a single “on and off” tone like with isochronic tones, rather the binaural beat is produced from ‘feeding’ each of your ears with a different tone. For example, if we put a tone of 100 hz into one ear, and a tone of 104 hz into the other, the brain will percieve a third tone of 4 Hz. This tone is produced because of the interference between the two tones.

Compare the previous recording of the isochronic tone with this recording of a binaural beat:

You have to listen with headphones for this one. You ‘hear’ a tone which is not really there, because your brain makes up the ‘vibrating’ rhythm you hear.

As a consequence of this, the resulting tone is much quieter compared to an isochronic tone. And that is, according to Dave Siever, the reason why actual brain entrainment is also less efficient with binaural beats.

Read this article for more on that topic.

 

How do isochronic tones work?

The brain receives the tone it is being ‘fed’ and starts to “mimick” this frequency. This phenomenon is called the “frequency following response” or just “brainwave entrainment”.

 

Brainwave entrainment - auditory evoked response to isochronic tones
The change in brainwave after a stimulus such as a ‘click’

 

Science catalogues our brainwaves into different frequency groups. And each frequency group has its own state and feeling accompanying it.

Roughly like this:

0.5 – 4 Hz called “Delta brainwaves” deep sleep
5 – 7 Hz “theta brainwaves” dream state, hypnagogic imagery
8 – 12 Hz “alpha brainwaves” relaxed wakefulness
13 – 30 Hz “beta brainwaves” alert wakefulness, concentration
30 – 100 Hz “gamma brainwaves” cognitive enhancement, migraine prevention, & more

 

 

Isochronic tones benefits – why use them?

So why would you use isochronic tones at all?

The idea behind isochronic tones is for the rhythmic pulses of sound to induce a certain state of mind with the listener.

By selecting an isochronic tone of a specific frequency, you can ‘nudge’ the brain to enter the selected brainwave state.

So, there are lot of reasons why you would listen to an isochronic track. With brainwave entrainment, it is stated that you can:

  • Increase your concentration and focus (beta stimulation)
  • Increase memory (specific beta and theta waves increase long-term memory and academic performance)
  • Increase your creativity (theta stimulation)
  • Help you to reduce your stress and become more relaxed (alpha and theta waves help you relax almost immediately)
  • Increase you emotional stability and mood (alpha stimulation helps your brain to produce more serotonin – which lacks when depressed)
  • Meditate more deeply (by training your brain to “be in theta”, your meditation is deepened)
  • Induce altered states of consciousness (such as lucid dreaming – certain alpha and theta frequencies, but played in the correct order!, help people to lucid dream)
  • and more…

It would depend on your goals.

 

Do isochronic tones work?

There is some mistrust and doubt as to whether they actually work. See my other post “Do isochronic tones work?” where I look into that question.

 

Where to find isochronic tones?

So you want to experiment with isochronic tones. Where should you get them from?

There are a few options:

 

Find an audio track or album [low budget]

There are tracks on youtube to listen to:

 

You can also find some on amazon for cheap:

Use a mind machine [most efficient]

Mind machines are probably the most efficient tools to produce brainwave entrainment with. Why?

Because they use not just isochronic tones, but also add visual stimulation in the form of flickering lights. The most efficient form of entrainment is not auditory, but visual.

As David Siever from mindalive.com says:

“auditory entrainment from isochronic tones produces about half of the entrainment effects as compared to flashing light.”

See the article Why Binaural Beats don’t Work as Well as These Alternatives for more about the superior results of visual stimulation.

 

Whatmind machines are available?

Different companies have been producing quality mind machines:

 

 

mindalive_logo

Mind Alive, led by brainwave entrainment veteran David Siever, has been producing quality mind machines since 1984, and as such is one of the pioneers.

The Digital Audio Visual Integration Device (DAVID 1), that he created in 1984 was the first device that I know of that used both flashes of light and pulses of tones to effectively guide the user into specific brain wave patterns.

Mind Alive’s range of products has since known many new models and updates.

I personally have been using the Mindalive DAVID Paradise since about 2002 or so, and am very happy with it still (even though it’s a very old – and discontinued – device).

 

DAVID Delight

The most recent series is called the Delight series.

The Delight is our most easy-to-use and lowest cost device for people who want simplicity and large, easy-to-use session buttons.  — MindAlive

My understanding is that it is geared more towards people who want a quick & effective device to use in their busy daily life, as opposed to more ‘hardcore’ brainwave or biofeedback fans who really want to delve into the subject of brainwave entrainment.

Plug and play

The DAVID Delight comes with a whole range of prerecorded sessions, which you can simply play, without having to think about “which brainwave frequency do I have to choose now?”.  So you don’t have to know a lot about brainwaves or brainwave entrainment at all.

It has ten very effective and popular sessions – two in each category:

David Siever from MindAlive showcases the DAVID Delight:

 

Downsides

One downside that I personally think that this model has, it that there is no function to choose your frequency manually. You always have to choose a program, with the length of time that comes with it.

But probably this is not much of an objection, unless you are the experimenter type. If you’re just looking for a machine that will relax you, or help you focus or meditate better, then this is a perfect machine.

I also think it’s a shame that you cannot program your own sessions, unless you buy the DAVID Session Editor separately (I believe it’s about an extra 70 USD). And even if you get the Editor, you can only create an extra 5 sessions (unless you start to overwrite the pre-recorded sessions).

But, again, this drawback applies more to people wanting to experiment, than to people with little interest in the technology itself.

 

Mindalive’s other mind machines

The DAVID Delight is Mindalive’s entry level machine: there are many more devices available.

Some are designed especially for students, some are specifically created for people with ADD/ADHD, and some come with the extra technology of CES (cranio-electrical stimulation). Professional instruments are also available.

Delight Lowest cost device for people who want simplicity and large, easy-to-use session buttons. With 10 sessions.
Delight Plus 25 sessions instead of 10. The extra sessions are particularly effective for more complex issues such as fibromyalgia and sleep disorders.
Delight Pro Same sessions as the Delight Plus, but also offers Cranio-Electro Stimulation (CES).
SMART 10 sessions specially designed to improve academic performance, reduce stress, boost mood, and improve concentration and memory in students.
ALERT sessions specifically designed for managing ADD/ADHD and other learning disorders.
ALERT Pro Same as ALERT Pro, but also includes CES.
OASIS PRO No isochronic tones or visual stimulation, only Cranio-Electro Stimulation (CES)

Eyes open

I just want to mention one additional accessory that is available from Mindalive (an accessory which I think is excellent): the “Viewhole Eyeset”, which allows you to use your DAVID with your eyes open.

Omniscreen-Viewhole
MindAlive’s “Viewhole Eyeset” allows you to have your eyes open during a mindmachine session

 

And why would you want to do that?

Some activities require that you have your eyes open, but you still want to train your brain to be in a certiain frequency. The Viewhole Eyeset is not standard included with Mindalive’s machines, but can be a great tool for certain people:

  • you can wear your DAVID during sports training
  • to increase reading comprehension and concentration (for example while studying)
  • to enhance your biofeedback/neurofeedback sessions (where you watch a screen with the feedback)
  • and help with phobia desensitization

Awesome feature.

MindPlace Kasina

 

A few pro’s about MindPlace’s machines:

  • the ability to manually set a frequency (just switch on and choose one frequency vs choosing a program which takes you through a sequence of frenquencies)
  • with the Procyon and the Kasina, you can create your own sessions too, with the included free software. . The The Procyon comes with a simple but very comprehensive editor.
    (But: although the Kasina also comes with a free editor, its not as comprehensive. To make more elaborate sessions you have to purchase a pricey application called Mind Work Station.)
  • efficient power use too. A set of duracells last a year of moderate use.

 

 

Conclusion

We transitioned a bit from the topic of isochronic tones to that of isochronic tones PLUS light stimulation.

The entrainment effect of isochronic tones is real. Especially if you use them in conjunction with light flashes.

If you meditate, it will take you in five minutes to where you normally get in an hour.
If you study, this will boost your concentration abilities (especially with Tru-Vu eyesets from Mindalive’s machines).

I would love to see isochronic tones, and especially mind machines, being used more in healthcare and stress management… Even though there there’s a lot of proof of them providing results, it still seems to be a fringe tool of the meditator. It would be good if that would change.

  1. Would either isochronic or binaural tones, listened in the daytime…put a person into trance making it dangerous to listen for example in a car?
