As a followup to my earlier work on binaural beats, I did another tracking study using Brain.fm. After fine tuning the approach and trying it for more than a month, I had a meditation breakthrough with Brain.fm. I found a hugely useful technique to help me have a smoother wakeup.
Each morning I conduct a tracking routine that includes heart rate variability (HRV), blood pressure, blood glucose and various body dimension measurements. In my last study, I had used Brain.fm for five-minute sessions without any discernable effect on my physiology. With feedback from the founders of Brain.fm, I retooled the tracking approach and tried again.
What I Did
The advice I got was that it takes 10 minutes to entrain the brain using binaural beats. I redid the tracking study so that I added a 10-minute session prior to taking a five-minute HRV reading. I wanted to ensure I had enough time listening to the binaural beats so the would be effective.
To determine the efficacy of Brain.fm’s binaural beat meditation soundtrack, I compared it to similar sounding music without binaural beats embedded. I wanted to compare the effect on HRV after 10 minutes of binaural beats vs an identical period of time without the beats.
How I Did It
I created a Google spreadsheet with a randomly generated number (0 or 1) for each day in the study. On waking, I would look at the sheet to determine whether to use Brain.fm (1) or a Pandora station I called “meditation” (0) that I set up with reference artists Deva Premal and Krishna Das.
If I used Brain.fm I would turn on the unguided meditation for 10 minutes and sit relaxed with normal respiration.
On completion of the 10 minute session, I put on the Polar H7 heart rate belt and the HRV Logger from Marco Altini and took a five-minute HRV reading while continuing to listen to the Brain.fm binaural beats.
On days when I used the Pandora station I would conduct the exact same procedure listening to the meditative music without binaural beats. On completion for both music sources, I would log my rMSSD measurement in the Google spreadsheet.
What I Learned
I was unable to find a significant difference in my physiological state when using music with binaural beats or music without binaural beats. Across 30 measurements, my average rMSSD with binaural beats was 50.9 vs 49.8 without binaural beats. The T Test showed that there was no statistically significant difference between the two soundtrack types (p=.87).
The Brain.fm site says that its binaural beats would have an immediate effect, and it appears that immediate means at least longer than 10 minutes. As a tactical approach to calming the body or the mind on waking, I don’t find it practical to have a preparatory session longer than 10 minutes. So for me, Brain.fm’s binaural beats are not a good tool to assist in my morning meditation.
The Breakthrough With Brain.fm
Though the soundtrack with embedded binaural beats did not have a discernable effect on my HRV readings, I did have a breakthrough with Brain.fm. My continued use of the product showed me without question that some form of music played during morning deep breathing work made it more likely I would engage in the activity and stick with it once I started.
There is something pleasant and energizing about sitting quietly for 10 minutes while my physical system comes online and wakes up. I found myself getting out of bed more readily knowing the session was the first thing I would do. Once I started the session it seemed to go quickly. Often I was surprised when my device indicated I had successfully completed the session.
For my morning sessions, I will still use Brain.fm. It has a pleasing format, it easy to use and I like the soundtrack. It is packaged well enough to be ready for use. I am realistic about it jacking my brain with frequencies in less than 10 minutes. That does not happen. Sometimes, however, relaxing tunes is just good enough to make a product useful and for that, Brain.fm is a winner.
