How Do You Use Isochronic Tones and What Are The Benefits?

Isochronic tones can be used in many different ways for multiple benefits. When I first discovered them around 2006 their most popular use was for meditation and relaxation. While they are still very popular for meditation, an increasing number of people are using them to help with studying, to improve focus and concentration in particular.

The main concept behind isochronic tones and brainwave entrainment methods, in general, is the ability to change your dominant brainwave frequency and guide your brain to an optimum or preferred mental state.

Stress or Anxiety Relief— When you are feeling stressed, agitated, angry or anxious your brain will usually be producing an increased amount of high beta activity. Low beta or alpha frequency isochronic tones will help to lower your dominant frequency, reducing feelings of stress or anxiety.Isochronic Tones Muscle Growth

Meditation and Relaxation— Sometimes it can be hard to really relax properly, and it can be even more difficult to reach a deeper state of meditation, especially for those new to meditation. Using low alpha and theta frequencies will help guide your brain to these deeply relaxing and sometimes enlightening mental states.

Increase Focus, Cognition and Memory— When it’s time to work or study, our brain isn’t always firing on all cylinders and ready to focus. If you are feeling tired, unmotivated and distracted, isochronic tones in the beta range will elevate your brainwaves up to a more optimal high focused state, and keep your mind there for the duration.

Research has shown that Alpha stimulation can also be helpful in improving your ability to retain and memorize information. So it has become very popular among students, who listen to it while revising and memorizing information for tests and exams.

Improving Sleep and for Power Napping– When you’re struggling to get to sleep, it’s very likely that your brain is producing too much beta activity. Brainwave entrainment tones can be used to reduce beta activity and increase more in the low delta frequency range. Helping you get to sleep faster.

Energy and Motivation– Increasing the amount of higher beta and gamma brainwave activity can help boost your energy levels, and make you feel more alert. It’s a great chemical-free alternative to caffeine and energy drinks.

How Do Isochronic Tones Work and Affect Your Brain?

Isochronic tones utilize a process known as brainwave entrainment, which can influence and drive brainwave activity to a more desired mental state. When the brainwave frequency starts to replicate that of the stimulus, entrainment occurs. With isochronic tones, the stimulus is in the form of a repetitive and clear beat/tone.

The repetitive and distinct beat of isochronic tones produce what’s known as an evoked potential, or evoked response in the brain. This is an electrical potential recorded from the nervous system, following the presentation of a stimulus. These electrical potentials can be seen and recorded using an Electroencephalograph (EEG).

Brainwave Synchronization

The process of brainwave entrainment relies on the natural phenomena of synchronization. Entrainment is defined as a ‘synchronization of two or more rhythmic cycles’ and you may already have seen or experienced it yourself, without knowing what was going on.

Here a few examples of natural synchronization:

Tuning forks– When you strike a tuning fork and then place another one next to it, the second tuning fork will automatically start to vibrate at the same frequency.

Pendulum clocks and metronomes– If you placed a number of pendulum clocks or metronomes in close proximity to each other, and set them all off swinging at different times, within a few minutes they will all start to swing together in unison.

Menstrual Cycles– It’s often found that when a group of women live in the same house together, their menstrual cycles will start to sync together. In college dorms, it’s regularly found that all the women on the same floor will have their periods at the same time.

Fireflies– If you are ever lucky enough to witness fireflies in action, you will notice that as the night wears on they will start to flash in unison.

Brainwave Activity– The frequency of your brainwave electrical pulses can be stimulated and influenced, by repetitive light flashing or sound rhythms and become synchronized to the same frequency of the light flashing or sound rhythms.

Frequency Following Response

This is known as frequency following response (FFR) when brainwaves become entrained and synchronized with the same frequency of an isochronic beat. The frequency of the stimulus/beats can then be changed and your dominant brainwave frequency follows along in step with it.

By using the power of FFR, your brainwave activity can be guided to a more optimum frequency, to enhance or improve your mental states.

For example, when you are very stressed or anxious, your brain will usually be producing an elevated amount of the higher beta brainwave activity. By stimulating your brain with lower alpha frequencies you can reduce the frequency of your dominant brainwave activity, helping to calm your mind and reduce the feeling of stress.

Isochronic Tones vs Binaural Beats
The discovery of binaural beats can be traced back to 1839, by German scientist Heinrich Wilhelm Dove. Whereas isochronic tones is a much newer discovery, with the first study being published by Arturo Manns in 1981, which showed that isochronic tones produce a much stronger brainwave entrainment effect, compared to binaural beats.

Many people incorrectly label isochronic tones as a type of binaural beat because binaural beats were discovered first and have been around for so long. In actual fact they are both just different methods of audio brainwave stimulation.

Isochronic Tones

They produce a more distinct tone/beat, which results in a stronger ‘cortical evoked response’ in the brain, making the stimulation more effective.
Standard sessions/tracks don’t require headphones.
With advanced sessions that require headphones, you have the ability to stimulate each side of the brain with a different frequency of beat, allowing you to lower or increase the activity in one side of the brain.

How to use Isochronic Tones

The most common way to use Isochronic Tones is for a short-term benefit. They provide a chemical-free alternative to things like coffee, energy drinks, alcohol, pills and other forms of medication. The key word here is ‘alternative’. They are not meant to replace any prescribed medication by a Doctor or medical professional.

How Long Do the Effects From Isochronic Tones Last For?

The most common way to use a brainwave entrainment is for a short-term benefit, to help guide your brain into a particular mental state at the time you need it. In a similar way to how you might take a sleeping pill before bed to help you get to sleep, or maybe drink an energy or some coffee drink to help wake you up and give you a boost of energy.

Because your brainwaves are synchronized and tuned into the frequency range you desire at that time, the effects are strongest while you are listening to the tones. After you’ve stopped listening the effects can still linger for a while afterwards. The timescale will vary from person to person and be affected by what you do after you’ve stopped listening.

As an example, if you use a mediation session to deeply relax you, you might stay feeling chilled out for a few hours afterwards. If you jump on a roller-coaster after listening, your brainwaves are going explode with beta and gamma activity from the adrenaline rush.

Some research suggests that the benefits from brainwave entrainment can last a lot longer, and still be seen for some time after you’ve stopped using it. Study participants have still maintained improved test scores a few weeks after the stimulation had ceased. Research on the long-term benefits has so far been minimal though, so how long the effects last is still up for debate.Isochronic Tones Muscle Growth

The Importance of Being Hydrated

It’s important to make sure you are well hydrated before listening to Isochronic Tones, especially when using the higher Beta and Gamma frequency tracks. Around 75% of the brain consists of water, and you need to keep it hydrated to function well, especially when you are doing things that require a higher level of concentration.

Headphones are Not Required for ‘Standard’ Isochronic Tones Tracks
One of the main promoted benefits of using isochronic tones compared to binaural beats is that you don’t need to use headphones. That said, using headphones can help to intensify the effect of an isochronic tones track, and the over-ear type can be very useful for blocking out external noises and distractions.

You will notice with some of my isochronic tones tracks that I say you need headphones. This is required on the more advanced sessions, where a different ‘frequency of beat’ is sent to each ear.

What’s the Best Volume Level to Listen to Them?

There isn’t an actual ‘peak volume’ level I can recommend for everyone because you’ll notice the beats will sound different depending on the equipment you use.

With many portable devices like laptops, mobile/cell phones and tablets etc. they don’t produce a lot of bass, so it can be hard to hear the tones on them and the volume often needs to be fairly high. You’ll often find you can have the volume a lot lower for the tones to be effective if you listen with headphones on.

My best advice is to start off with the volume around half way and adjust it up or down from there to suit your preference. You’ll want the volume loud enough to hear the tones quite clearly, but never so loud that it hurts your ears.

Increasing the volume level can have some impact on the power of the tones. So sometimes if you find a track not having a strong effect on you, try increasing the volume a little bit, or try using headphones if you haven’t done so before.

Are Isochronic Tones as Effective When Combined with Music?

For many people, isochronic tones can sound quite harsh to listen to on their own, especially when you are first getting used to the sound. To help improve the sound, they can be combined with music or ambient nature sounds, which is the most common way people listen to them.

A popular opinion in the brainwave entrainment community is that listening to isochronic tones without music produces a much stronger effect. However, in the study by Doherty, Cormac. “A comparison of alpha brainwave entrainment, with and without musical accompaniment” (2014 ), it was concluded that brainwave entrainment was equally effective for isochronic tones, both with and without music.
