The International Institute of Therapeutic Intervention and Learning is a great resource for those utilizing brain entrainment and neurofeedback. Their soundscapes specifically target areas where a client may be having trouble. For those unfamiliar with Brain Entrainment, it refers to the capacity of the brain to naturally synchronize its brainwave frequencies with the rhythm of periodic external stimuli, most commonly auditory, visual, or tactile. The external stimuli elicit the brain’s ‘frequency following response’, encouraging the brainwaves to align to the frequency of a given medium. FFR can be useful because brainwaves are very much related to mental state. For example, a 10 Hz brainwave is associated with relaxation, so a 10 Hz sound pattern would help reproduce the relaxed state in your brain.
