Aatom is an ambient producer who lives and creates music in Sussex (UK). Music As Medicine Vol 1 is a hybrid ambient / therapeutic album which aims to help sufferers of Alzheimer's. As Aatom explains "This music is designed to have a clear enough 40hz signal, which is almost inaudible at normal volume levels, to induce gamma brainwaves. The music itself is designed to be soothing and gentle, and is in harmony with the 40hz frequency. The overall effect means the listener can relax, undistracted by the noise, and drift off, meditate, or just sleep and let the gamma waves do their work."
Apparently, scientists have discovered that these gamma brain waves may lead to a clearing of beta amyloid plaques in the brain, a key abnormality in Alzheimer's disease.
Although available is smaller slices, the full piece is 52 minutes long and I recommend that you take time out to listen to it in one sitting. There's a calm drift to everything, like falling through a soundscap extremely slowly. If nothing else, it might just transport you away from the daily stresses of life for an hour.
