Sound Therapy Improves Cognitive Flexibility, which COULD Save the World


By Erin Stair, MD, MPH

Since I created ZENTones, I try to keep up with any/all new research published in the realm of sound therapy. If I find a study with positive results, I store it in a digital library so I can share it with any of my clients/customers who are more interested in the science of how sound therapy works.

A new study published in Frontiers in Psychology showed that high-frequency tones increased cognitive flexibility. This study tested the theory of binaural beats, yes, but specifically tested binaural beats in the gamma range, or 25-100 Hz. Binaural beats in the gamma range are traditionally associated with a state of heightened sensitivity and/or what some folks call “enlightenment.”

(I should note that the beats in this study were delivered in a stand-alone fashion and NOT mixed in with other musical creations. Beats, in a therapeutic sense, are not music, so be careful when you download random programs from I-tunes. Most of the research on binaural acoustics only use the raw beats, with very little background music. If you want to use binaural beats as sound therapy, you should always try to re-create the sound programs that were used in published studies with successful outcomes. Not the ones that “sound cool.”)

So, increased cognitive flexibility: Is that a good thing?  What does it even mean?

Cognitive flexibility is the mind’s ability to transition and/or adapt when presented with a new situation or new information. The faster your mind can adapt to the new situation or information, the greater your cognitive flexibility. If your mind is slow to adapt or doesn’t adapt at all, you aren’t very flexible…, at least in the cognitive sense.

The importance of cognitive flexibility is that it can:

1) Help you transition from one topic to another: In short, the more cognitive-flexibility you have, the less likely you are to get stuck on one thought or one topic in a conversation or a situation in which many topics are presented.

2) Make you a better observer: You won’t lose sight of the forest for a tree. For example, if you are tasked to observe a room,  more cognitive flexibility will allow you to “see” more of the room. You are less likely to get stuck on one object in the room, and see more of the room’s components. Therefore, having more cognitive flexibility will give you a better idea of what is in the room, what the room is used for, who uses the room, etc. Someone with less cognitive flexibility may only focus on one table or a carpet in the room.

3) Allow you to change and evolve your believe system: In my opinion, this may be the most important benefit, because it speaks to how we evolve as individuals, as societies and as a world.  When presented with new information, one with greater cognitive flexibility has the ability to update or change his/her beliefs, rather than stick to outdated and/or untrue beliefs.  One with cognitive rigidity would have a very tough time changing his/her belief system, and would instead remain attached to traditional and outdated beliefs. For example, think of your friend who is a die-hard atheist.  (Everyone always has one of those.) Imagine if that friend is presented with newly-discovered, powerful information that essentially confirms the existence of God. (Hypothetically speaking)  Would your friend properly evaluate the new information and update his/her belief about the existence of God, or would he/she be cognitively rigid, avoid the new information and continue to be a die-hard atheist?

4) Make you a better problem-solver: Those with greater cognitive flexibility are better at dissecting a problem into manageable components and coming up with a solution. Those who are more cognitively rigid have a much tougher time doing that.

Did you ever think a sound program full of boring old beats could change the world?  I just gave your four reasons how it could. 😉

Till next time,

  1. I should change my music genre now. I also want to improve the Cognitive flexibility of my mind. I always seek help from my playlist when I feel stressed and down. Music can really work wonders with the feelings of human. Thank you Dr. Eeks for sharing the study and for listing down the four reasons why sound program full of boring old beats could change the world.

  2. Thanks for sharing the best article posts they very useful to us. You made a good site and giving us such a clear and nice tips and suggestions they very help us. I am very satisfied with your site and also with your posts they amazing thank you all
