There isn’t really a one-size-fits-all track or frequency range which is right for all kids while doing homework. So that does make it difficult to recommend one thing in particular, and why I have a number of tracks for studying and focus. If they have already learnt and understood the information, but are just trying to commit it to memory for a test, then I would recommend an alpha track, like the Memorization Study Aid product I have with the 10.4Hz frequency you referred to. If they are still trying to fully understand what is being taught in a workbook, then I would recommend a track that is mainly beta frequencies, like my Study Focus tracks. In the middle, I have a number of tracks which use a combination of beta and alpha wave frequencies, like Study Booster, Study Enhancer and Cognition Enhancer. The last 3 use similar frequencies but deliver the tones and brainwave entrainment effects in different ways. As we are all wired a little differently it does sometimes take a bit of trial and error, to see what method or frequency range works best for the individual. These types of tracks are made for a general audience. In an ideal world, you would hook up to an EEG and see in real time exactly what a person responds to best, depending on the goal and current state of mind.
In simplest form, they are an audio technology which are used for (safe) brainwave entrainment. Our subconscious mind operates, throughout the day and night, in various brainwave state frequencies, measured in cycles per second (Hz) These frequencies range from the slowest (Delta) frequencies experienced in deep, dreamless sleep and in deep meditation where your conscious-awareness is fully detached, to the fastest (Gamma) frequencies associated to stimulating flow states, high-level thinking and information processing. There are actually 5 known brainwave state frequencies each having their own set of unique characteristics:
As you close your eyes, this session quickly lulls you down into deep delta sleep, where the body recovers and grows. The session starts at a waking frequency, soon taking you down deep into delta, with stops at sigificant beneficial frequencies such as the de-stressing 10Hz, the grounding 7.83Hz Schumann resonance (SR), and the deeply relaxing 5.5Hz. You’ll soon find yourself in a deep, healing sleep. If you’re particularly stressed, try listening to Power Chill before starting
