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).

Ever wish a stress superhero could save you from the tension of traffic jams, chaotic meetings, arguments with your spouse, or a toddler’s tantrums? Well, you can be your own stress-busting superhero. Using your senses, you can tap into the power to reduce the impact of stress as it’s happening and stay in control when the pressure builds. Like any skill, learning how to ease stress in the moment takes time, experimentation, and practice- but the payoff is huge. When you know how to quickly relieve stress, you can stay calm, productive, and focused, no matter what life throws at you.
Chris is as good as it gets! He is amazing with color and color correction, believe me I know! Myself and two daughters only go to Christopher. Stacey is top notch as well, you can't go wrong having her cut or color you. The Salon is clean and welcoming. His on-line booking makes life so easy and they call and remind you as well. Can't say enough about how great this salon is!
Binaural beats between 1 and 30 Hz are alleged to create the same brainwave pattern that one would experience during meditation. When you listen to a sound with a certain frequency, your brain waves will synchronize with that frequency. The theory is that binaural beats can help create the frequency needed for your brain to create the same waves commonly experienced during a meditation practice. The use of binaural beats in this way is sometimes called brainwave entrainment technology.
When you type “brainwave study music” into your search bar, more than likely, you are going to get a good variety of results: alpha brain waves, gamma, theta… But how do you know which one is the best to use, and when? You’re in luck, because in this article, we will be exploring just that! But first, let’s quickly take a look at the 5 different types of brain waves. Types of Brain Waves Here is a brief summary of each type of brain wave and how it affects your brain — beginning with the … [Read more...]
it says the following: “Running a delta sleep session throughout the night is not recommended as it can interrupt the normal sleep cycle”. I’ve been looping pure delta isochronic tones for about 5 days now, and have had quality sleep. Should I continue looping delta or should I let the videos play out without looping them? Will it will harm my health to do loop delta while I sleep?
This session uses a proven technique for inducing deep relaxation, playing one frequency for two minutes, then alternating to a second after a 30-second ramp, then reversing the process. The first half of the session switches between a serotonin-boosting 10Hz and the grounding and rejuvenating 7.83Hz Schumann resonance. The second half of the session goes even deeper, alternating between the relaxing 7.83Hz and 6.3Hz, a frequency associated with releasing anger and irritability. The session ends on a chilled out 10Hz.
