Isochronic tones are used in the process of brain wave entrainment. Brain wave entrainment refers to a method of getting brain waves to sync with a specific stimulus. This stimulus is typically an audio or visual pattern.
Brain wave entrainment techniques, such as the use of isochronic tones, are being studied as a potential therapy for a variety of health conditions. These can include things like pain, attention deficit hyperactivity disorder (ADHD), and anxiety. In a word, many studies indicate isochronic tones for healing benefits.
What Are Isochronic Tones?
Isochronic tones are single tones that come on and off at regular, evenly spaced intervals. This interval is typically brief, creating a beat that’s like a rhythmic pulse. They’re often embedded in other sounds, such as music or nature sounds.
Isochronic tones are used for brain wave entrainment, in which your brain waves are made to sync with the frequency that you’re listening to. It’s believed that syncing your brain waves to a certain frequency might be able to induce various mental states.
Isochronic vs. binaural and monaural beats
You may have heard about other types of tones, such as binaural and monaural beats. But how are these different from isochronic tones?
Unlike isochronic tones, both binaural and monaural beats are continuous. The tone isn’t turned on and off as it is with an isochronic tone.
Isochronic Tones for Healing of Mind and Body
It’s thought that using isochronic tones for healing and other forms of brain wave entrainment can promote specific mental states. This may be beneficial for a variety of purposes including:
- promoting healthy sleep
- alleviating stress and anxiety
- perception of pain
- mood enhancement
How to Best Use Isochronic Tones
You can choose the range of frequencies you want to experience. For example, if you want to focus attention to concentrate, you would choose an isochronic tone in the alpha wave range (7-13 Hz). On the other hand, someone wanting to reach deep meditation would set them down into the theta wave range (4-7 Hz) with the sleep music, sun meditation, chakra tuning, and prosperity track. Different ranges of isochronic tones for healing effects will result in different benefits.
These tones need to be audible, so you will hear them along with the music in the brain waves to the desired state more quickly. Headphones are not necessary (although often still recommended).
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 helping you get to sleep, or maybe drink some coffee or an energy drink to help wake you up and give you a boost of energy.
The effects are strongest while you are listening to the tunes because your brainwaves are synchronized and tuned into the frequency range you desire at that time. 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.
Are Isochronic Tones Safe?
There haven’t been many studies into the safety of isochronic tones. However, there are a few things you should keep in mind before using them:
- Keep the volume reasonable. Loud noises can be harmful. Noises above 70 decibels over a prolonged period of time can cause hearing damage. For example, normal conversation is about 60 decibels.
- Use caution if you have epilepsy. Some types of brain entrainment may cause seizures.
- Be aware of your surroundings. Avoid using the more relaxing frequencies when you’re driving, operating equipment, or performing tasks that require alertness and concentration.
Isochronic tones are tones of the same frequency that are separated by short intervals. This creates a rhythmic pulsing sound.
Isochronic tones are used in the process of brain wave entrainment, which is when your brain waves are deliberately manipulated to sync with an external stimulus like a sound or image. Different ranges of isochronic tones for healing effects will result in different benefits. Other examples of auditory entrainment types are binaural and monaural beats.
Like other types of brain wave entrainment, using isochronic tones could potentially be beneficial for a variety of health conditions or for enhancing mood. However, research into this area is currently very limited.
