Theta stimulation: There appears to be no benefit associated with using theta stimulation for cognitive functioning, mood, or stress relief. While theta may be a useful way to induce sleep or alter your state of consciousness, there really isn’t much science supporting entrainment in this particular range for most purposes. Photic stimulation of theta between 5 Hz and 7 Hz can be useful for headaches.

Because of the controversy over the safety of estrogen replacement therapy, many women turn to natural and herbal products for relief of fluctuating hormones. One of the best and most stabilizing hormones a woman can have is progesterone. In estrogen replacement therapy, progestin has been used. It is very similar to progesterone and behaves nearly the same way in the body, but it causes all sorts of side-effects, including increasing the risk of cancer. It is, however, cheap and easily extracted.


There are many sources of binaural beats on the internet and YouTube to check-out and experiment with yourself – I recommend using headphones for optimal effectiveness. However, like most things, not all binaural beats are created equally (especially if they are free on the internet) and therefore not as effective or enjoyable to listen to. This is why I HIGHLY recommend the binaural beats created by master audio technician, music producer and meditation teacher, Cory Allen – which can be found here:

Heart rate variability: A new study suggests that among those with low HRV (heart-rate variability), brainwave entrainment can increase HRV. Researchers studied individuals ages 20 to 70 and administered alpha brain stimulation. The alpha wave stimulation resulted in greater heart-rate variability. Since a low HRV is associated with early mortality and poor psychological and physical health, efforts made to increase it should be regarded as beneficial.

6. Razor Sharp – Yes, just as the name suggests. You should use this when you are about to tackle tasks that need high levels of attention, like handling hefty work related tasks, reading for exams, deep studying, problem solving or anything else that requires deep focus. It will assist you to clear the job with lightening speed and super accurately.
In March I started using the CDs that I affectionately call “Meditation for Dummies” and am very pleased with the results so far. My blood pressure has dropped, I am sleeping better and notice that I feel much more calm and less stressed. Instead of feeling that I need to “find the time” in my schedule to meditate, I look forward to that totally relaxing half hour–that peaceful feeling of floating.
* Headphones/Earbuds are Required for Binaural Tones to be Effective as the Left Ear and Right Ear Audio must be isolated for the Brain to perceive the inaudible low-frequency difference between the two sides. ** Changes to Orientation Support: With the upcoming arrival of several new devices with new screen-sizes and aspect ratios, iOS 8 required a re-write of our iPhone and iPad UI to support these devices, and as part of that, we have returned the app to a Portrait-only view for now. Once we know what these future screen dimensions and Aspect Ratios are, and have time to work with the real devices, we can implement a new Landscape UI for the iPad.
The pitch frequency measures and describes what a beat sounds like, i.e. does the isochronic beat have a deeper bass sound, or is it high pitched and sharper sounding? The beat waveform frequency describes how many times the beat is repeating per second, i.e. how fast it is beating. You don’t really need to concern yourself about the pitch frequency, as that doesn’t have a direct influence on brainwave entrainment and doesn’t play a part on the measurement on an EEG. I only mentioned it because you were referring to humans not being able to hear below 20Hz. I change the pitch frequency just to suit the mood of the track. For tracks that are to be relaxing, for meditation or sleep, I tend to use a lower pitch frequency so it sounds deeper and more relaxing and I never have that lower than 100Hz. For an energizing, high focus track I might use a more higher pitched 200Hz isochronic tone, because that is sharper sounding and less likely to make you feel sleepy. That’s all you really need to know about the pitch frequency.
An invigorating, brain-sharpening session, this audio starts at 14Hz, a beta feel-good frequency and SR harmonic. It then steps up in six-minute harmonic increments, gradually up to gamma 39Hz, leaving you feeling mentally stimulated and full of energy. A binaural beat track supports the main frequencies for those wearing headphones. Uplifting background music with embedded amplitude modulation provides a further layer of entrainment. Excellent for use as a morning alarm clock, ahead of a big night out, or to inspire those tired trips to the gym.
