Isochronic tones work by influencing your brainwave activity and they can’t directly affect the body. That said, the brain does control the body, so sensations and feelings can sometimes be felt in the body after stimulating your brainwave activity. Some people who are new listeners of this type of audio can sometimes feel tingling sensations in their body. Not everyone feels this and these sensations usually stop once you get more used to using the audios. Isochronic tones are considered as a safe technology. However, sometimes they can leave you feeling temporarily fatigued, especially if you listen to them for an extended period (hours) when you first start using them. If you felt fatigued, I would recommend using them for a much shorter period while you are getting used to them and ensure you are well-hydrated.

Maybe a favorite popular song, a certain piece of Classical music, a raucous dance beat, the pulse of Reggae, Indian, or African drums, or the chanting of Gregorian or Tibetan monks, but you probably know how the sound of music, drumming, or chanting is capable of transporting you into an altered and joyous state of mind and uplifting your spirits.

The studies included in the recent reviews of Tai Chi and yoga indicate that sessions between 60 and 90 minutes performed 2 to 3 days per week were effective in reducing stress and improving feelings of well-being (7,14,17). A study conducted in a worksite environment showed that 15 minutes of chair-based yoga postures was effective in reducing acute stress when assessed by self-report and with physiological measures (e.g., respiration rate and heart rate variability parameters). This finding indicates that shorter duration sessions can be effective in reducing acute stress with this type of exercise (15).
Targeted hemispheric changes: Some speculate that specific alterations in brain waves can be made on an individual basis. In other words, you can target one frequency in one hemisphere (via the right ear) and another distinct frequency in the other hemisphere (via the left ear). The left ear affects the right hemisphere and right ear affects the left hemisphere.
Theta brainwaves are next highest in frequency above delta and are especially important for many people using brainwave entrainment and meditation because theta waves are at a threshold, forming a link between wakefulness and the subconscious mind. Theta waves bridge between our awake self and the creative and insightful understandings from below our conscious awareness, and while they are not common in awake adults, they are normative for children under 13 years old. 
That is a general assumption people make but there isn’t really much science to back it up. What we do know though is that isochronic tones are ineffective below 4hz, and possibly a bit higher. So for theta and delta entrainment you are best off with binaural beats. In my experience binaural beats will be very effective all the way up to around 40hz.
Hi Steve, sorry I missed this comment. That’s a tough question. I’d have to say Earth Vibration or Spiritual Awakening. The EV track is amazing, it has these occasional subtle wolf howls that integrate with the track and create a melodic atmosphere. From a production point of view it is really good. Spiritual Awakening is really relaxing. It uses natural ambience and a sparse hang drum, an instrument I love. Both are theta tracks. Earth Vibration says it is 432hz, but that refers to the frequency of the music is tuned to. The sound waves are 7.83hz theta (I checked… Read more »
Proceedings of the 9th Conference on Interdisciplinary Musicology – CIM14. Berlin, Germany 2014 nature (birds and wind) while the second group listened to theta binaural sound waves. Both groups listened to the stimulus through headphones. During the experiment, participants were monitored with the Neurosky Mindwave Interface, which was connected through Processing to a Max Patch that saved all the data in a ‘.csv’ file. Before the stimulus, a baseline EEG took place and the participants answered the “Trait” part of the STAI test and a pre-experiment “State” version of the test. After the experiment, participants answered a post-experiment “State” STAI and a post-experiment EEG also took place. Each experiment was developed with one participant at a time in a controlled environment. American Psychological Association Ethical Principles and Code of Conduct 2002 were followed. 6.

STIMULI • Experimental group – Binaural Theta frequencies • Control group – Nature environmental sounds 11. PROCEDURE • The participant is asked to read and sign a consent letter. • A pre-experimental three-minute encephalogram is taken and the participant is required to answer State and Trait STAI tests. • The corresponding stimulus is played during ten minutes and an EEG is taken. • The State STAI test is answered and a post-experiment EEG is taken. 12. VISUAL DATA ANALYSIS The stimuli took place from second 180 to second 774. (Graphs in Annex 1) 12.1 Theta The significant time range was from second 3 to second 948. The most significant moments were the following: (see annex A1.5) s = 189; p = 0.014; t = 1.025 s = 495; p = 0.002; t = -1.923 s = 780; p = 0.001; t = -2.349 12.2 Meditation The significant time range was from second 240 to second 912. The most significant moments were the following: (see annex A1.3) s = 240; p = 0.042; t = .0.685 s = 522; p = 0.013; t = 0.546 s = 702; p = 0.016; t = 0.897 12.3 Delta The significant time range was from second 12 to second 954. The most significant moments were the following: (see annex A1.10) s = 177; p = 0.046; t = 1.696 s = 627; p = 0.016; t = -1.366 s = 912; p = 0.007; t = 1.758 12.4 Attention The significant time range was from second 243 to second 870. The most significant moments were the following: (see annex A1.11) s = 243; p = 0.021; t = 0.672 s = 513; p = 0.005; t = 0.722 s = 753; p = 0.017; t = 0.383 12.5 STAI Variations were found in STAI-State pre-experiment and post-experiment: • Control group results rose from 19 to 21 • Experimental group results decreased from 20 to 15. Variations between both groups were found in the STAI –Trait: • Experimental group with a score of 32 in STAI-T test outran control group by 4 points 13. RESULT ANALYSIS Samples were analyzed every three seconds. They were later statistically distributed according to the T-student test in order to find differences between both groups. For this experiment, the significant p value was p<0.05, this means that the probability is less than 5% T-student detailed analysis: • The meditation value is similar in both groups, (see graph A1.3). T-student function shows less significant points for this parameter. This means both stimuli induced relaxation to the participants. • Theta values are higher in the control group, especially after second 510 (see graph A1.5) almost at the middle of the stimulus. • STAI “State” post-experiment results from the experimental group are higher than the control. Therefore, theta binaural frequencies were more effective as an anxiolytic stimulus. (see graphs A1.1 and A1.2) • Delta values are higher after second 285 in the control group (see graph A1.10). This indicates deep sleep and losing of consciousness over the body (unconscious relaxation). It is highly possible that the participant fell asleep or got to the first stages of sleep. • There is a significant difference in delta between experimental and control groups after second 870 (post-stimulus).

The most common way to use a brainwave entrainment is for a short-term benefit, to help guide your brain into a particular mental state at the time you need it.  In a similar way to how you might take a sleeping pill before bed to help you get to sleep, or maybe drink some coffee or an energy drink to help wake you up and give you a boost of energy.

Recently developed entrainment software has been designed to correct specific imbalances in hemispheric activity associated with undesirable mind-states. For example, people suffering with depression often have more activity in the right hemisphere, and specially designed brainwave music decreases this activity while increasing activity in the left hemisphere, reducing depression.
I personally believe in this type of sound. It works for me. Isochronic tones are the most powerful type of brainwave entrainment, utilizing equal intensity tones, increasing the pulse speed, and synchronizing your brain with the rhythm. Isochronics use a distinct and clean wave form which is designed to harmonize with the brain much more efficiently. Headphones are optional but recommended(from Healing Music CD and MP3).
Depression: Currently there is no substantial evidence to support the idea that brainwave entrainment treats depression in adults. Some evidence goes as far as to suggest that the wrong entrainment protocol (e.g. slow wave stimulation) may actually increase certain measures of depression. Stimulation of delta and/or theta, will likely worsen the condition and alpha is unlikely to have an effect.
Whatever your powerful mind believes to be true, it makes real in your experience. Your subconscious is a powerhouse of intelligence in action. It acts on your beliefs and perceptions. Theta binaural beats combined with subliminal messages reach deep into your subconscious mind to instill new ideas and beliefs. In a short time you’ll notice positive, even remarkable changes occurring in your life. The results are profound.

Binaural beats are acoustically generated frequencies that match the frequency bands of brain waves and are therefore considered a means to inducing neurophysiological relaxation. There is, however, large dispute on the scientific quality and validity of extant research on binaural beats. Thus, the effect of a binaural 10Hz (Alpha) stimulation on subjective and physiological parameters ... [Show full abstract]Read more

Since the mid-1800's scientists and researchers have experimented with sound waves, in particular binaural beats and isochronic tones, to try to guide the brain into a specific frequency using pulses of sound that can stir productivity and creativity or cause feelings of calm and relaxation. The practice of brain training and brainwave entrainment are not entirely new but the use of computer generated pulses and tones has become more popular of late since the results from isochronic tones have proven to be more effective than binaural beats.
B6 is part of the B-complex vitamins and something you probably get an adequate amount of as part of a predominantly vegetable-based diet. However, during menopause, you may need to increase it more than your dietary intake allows. In this case, a low-level B6 or pyridoxine supplement can help give you a boost. In fact, taking a general B-complex supplement that includes adequate levels of B6 will provide you with an increase of all of the B vitamins, mostly because they work together.
The effects are strongest while you are listening to the tones because your brainwaves are synchronized and tuned into the frequency range you desire at that time.  After you've stopped listening the effects can still linger for a while afterwards.  The timescale will vary from person to person and be affected by what you do after you've stopped listening.
In moderation, religious and spiritual practices can be great for a person’s life and mental well-being. But religious fundamentalism — which refers to the belief in the absolute authority of a religious text or leaders — is almost never good for an individual. This is primarily because fundamentalism discourages any logical reasoning or scientific evidence that challenges its scripture, making it inherently maladaptive.
