D<strong>oes Brainwave Entrainment Work<\/strong>?<\/h2>\n\n\n\n<p>Let&#8217;s go straight to the most important point: does it <em>actually <\/em>work? Does brainwave entrainment work?<\/p>\n\n\n\n<p>The simple answer is <strong>yes<\/strong>.<\/p>\n\n\n\n<p>I know this from personal experience because I have observed entrainment in myself on both an objective and subjective level.<\/p>\n\n\n\n<p>On an <strong>objective level,<\/strong> I did some EEG analysis on my brainwaves while listening to some entrainment tracks. What I found was brainwave activity that was not typically present during normal times. This is documented in my <a href=\"https:\/\/sinewavelab.com\/sonofields\/brainwave-journal\/\">brainwave journal<\/a> \ud83d\udcd5<\/p>\n\n\n\n<p>On a <strong>subjective level<\/strong>, I have experienced some bursts of creative ideas, among other things, while listening to those same tracks. This is worth what it&#8217;s worth but seemed convincing enough to me.<\/p>\n\n\n\n<p>But since this is a complex topic, I will present some extra details to you, and let you decide for yourself.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Is-Brainwave-Entrainment-Scientifically-Proven\">3. Is Brainwave Entrainment Scientifically Proven?<\/h2>\n\n\n\n<p>While it is true that not all scientific studies have been able to replicate the effects of brainwave entrainment, it is nevertheless a fact that meta-analyses concluded that brainwave entrainment, in general, is an effective therapeutic tool.<\/p>\n\n\n\n<p>Below you will find an extensive list of what science says about brainwave entrainment. This list may be extensive, but it still only covers the papers I have read. I have not read all the papers, so let&#8217;s keep that in mind. But I think there&#8217;s enough here to form a proper general picture.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>To keep things fair and unbiased, both positive findings and negative findings

id=\"Proposed-Limitations-of-the-Studies\">4. Proposed Limitations of the Studies<\/h2>\n\n\n\n<p>For the studies that have failed to demonstrate brainwave entrainment on the brain, or the subjective minds of the subjects, some explanations have been proposed as the possible causes, such as problems with the:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Experimental protocols.<\/li>\n\n\n\n<li>Stimulus duration.<\/li>\n\n\n\n<li>Beat frequencies.\n<ul class=\"wp-block-list\">\n<li><strong>My comment:<\/strong> this is why I like to test the entrainment tracks I create, such as the <a href=\"https:\/\/sinewavelab.com\/sonofields\/?post_type=al_product&amp;s=NEX\">NEX bundle<\/a>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Attention to stimuli.\n<ul class=\"wp-block-list\">\n<li><strong>My comment:<\/strong> I remember reading in one of the studies that failed, that subjects were listening to binaural beats <em>while watching a muted nature DVD<\/em>. Binaural beats require some level of attention to work properly. Learning that a study was conducted where subjects were watching a nature DVD instead of focusing on the binaural beats made me put into question the ability of researchers to devise nuanced testing.<\/li>\n\n\n\n<li>One study found that gamma response is larger over frontal and central areas when participants were told to pay attention to tone stimuli.<\/li>\n\n\n\n<li>In one study, attention-dependent modulation of auditory steady-state response patterns was observed for 20 Hz Beta stimulation. <\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Individual differences.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">5. Brainwave Entrainment Dangers<\/h2>\n\n\n\n<p>People may wonder if brainwave entrainment technologies are dangerous for some reason. As of now, there have been no reported major dangers in scientific studies. Usually, the worst thing that can happen is that the entrainment track does nothing to you.<\/p>\n\n\n\n<p>However, if you read the previous sections, you know that some minor negative aspects can occur:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Increased Depression<\/strong>, <strong>Anxiety, and Tension<\/strong>: Certain frequencies, such as 6 Hz Theta and low-frequency delta waves, have been associated with increased depression scores or subscores in some studies, and also confusion, bad temper, and fatigue.<\/li>\n\n\n\n<li><strong>Sleep Quality<\/strong>: Although many studies suggest that brainwave entrainment can improve sleep quality, there are also findings indicating increased sleep onset latency and delays in the occurrence of stable Non-REM sleep with certain types of stimulation.<\/li>\n\n\n\n<li><strong>Attention and Cognitive Effects<\/strong>: Binaural beats have been observed to decrease verbal memory recall in one study. <\/li>\n<\/ul>\n\n\n\n<p>We should keep in mind that it&#8217;s unlikely that there is something wrong with specific frequencies like 6 Hz and such. Instead, it&#8217;s likely we&#8217;re dealing with a complex situation with lots of variables which, in one specific case, have affected negatively someone. If circumstances had been slightly different, maybe that same frequency could&#8217;ve been beneficial instead. We know this has to be the case, because 6 Hz (to use as an example) is not consistently known to cause increased negative emotions in listeners.<\/p>\n\n\n\n<p>Other dangers can be avoided by using common sense, such as:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li> If you are listening to audio entrainment tracks, don&#8217;t listen the it loud, otherwise, you can damage your hearing. Entrainment tracks don&#8217;t require lots of volume to affect your brain waves, this is a known fact (60 dB SPL is enough).<\/li>\n\n\n\n<li>If you suffer from epilepsy, avoid photic and audiovisual entrainment tracks, as they contain flashing lights.<\/li>\n\n\n\n<li>If you find listening to monaural beats or isochronic tones annoying or boring, try doing it mixed with music instead (binaural beats may lose some effectiveness, since it&#8217;d be harder to focus on the beat itself).<\/li>\n<\/ul>\n\n\n\n<p>One last possible danger that may arise from brainwave entrainment is focusing on brain wave ranges that you personally don&#8217;t need to entrain, for instance, if you are an anxious person, don&#8217;t focus on high-beta entrainment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Get-Started-with-Brainwave-Entrainment\">6.
