Binaural Beats for Curious Surfers
Tuesday, February 17th, 2009Binaural beats are auditory brainstem responses that happen when opposite ears (perhaps yours!) hear sounds of slightly different frequency.
Just as your brain puts together two 2-dimensional signals from your eyes, then processes them to get a 3D stereo image, your brain also processes two separate auditory signals (one from each ear) and combines them into a super duper spatial auditory experience.
But a funny thing happens when your brain combines two steady but slightly different signals: it creates a pulsing beat equivalent to the difference of their frequencies. The best part, at least for curious surfers hunting yet another strange but safe way to alter their state of consciousness, is that brain waves gradually follow and eventually synchronize themselves with the frequency of the pulsing beat.
In short, if you want your brain waves operating at 5 Hz (a wave frequency typically associated with deep meditation) you put a 400 Hz signal in your left ear, and a 405 signal in your right ear, then sit back and let your brain assimilate and follow the binaural beat.
Brain Waves and States of Consciousness
Most states of consciousness have corresponding brain wave frequencies.
When your brain waves are in the beta range (15-40 Hz), you are in an alert, actively working state. For example, you’re on a TV game show answering a question that may net you $100,000 after taxes. Or, you’re breaking huddle on the 50 yard line, four points down with three seconds on the clock. Or, you’re giving a friend directions to your barbeque party over the phone. There are high and low levels of Beta, but in all of them, your brain is actively engaged.
When your brain is operating in the alpha range (9-14 Hz), you’re relaxed and reflective. Taking a quiet walk in the garden? Alpha. Just came home from work, opened a beer, hit the couch? Alpha.
The theta range (5-8 Hz) shows up during very deep relaxation and meditation. During theta, you’re on autopilot, and ideas seem to flow into your brain from nowhere. Even if you never assume a lotus position, you’re probably in a theta state more often than you’d think. How about the last time you arrived at work and didn’t remember the drive? That was theta. And remember when a great idea came to you while you were taking a shower or brushing your teeth? Yep…that was your brain on theta, too.
There’s also the delta range (1.5-4Hz) of brain waves which occur when you’re experiencing deep, dreamless sleep. This one, you probably don’t recall ;-)
Chasing Some Deep Relaxation
If your brain feels like it’s stuck in an anxious Beta state, and you’re having trouble shifting down into a more relaxing, meditative, alpha state of consciousness, put on your headphones or earbuds, and feed your brain some binaural beats: Infinite Bliss with Stereo Binaural Beats.

Many Americans are ok with sending their neighbors’ sons and daughters to the Middle East for five years to become paraplegics for oil. But when it starts costing twice as much for us to gas up the
Oil sure causes a lot of problems, and the United States hardly has any left, and when we invade another country to secure their oil for ourselves, we only end up blowing

Since a 49 centimeter squid’s beak was previously found in the stomach of a sperm whale — and since the total squid size to beak size ratio is incremental, not linear — scientists believe there are still colossal squid in the ocean that are a great deal bigger.
Let’s use George W. Bush as an example. To the right we see Bush, with both sides of his brain intact.
Meet Bush with two right side brains (actually, the right-brain controlled left side of his face and its mirror image.)
Now, meet Bush with two left side brains (the right side of his face, doubled.)
