I'm a guy with ADHD which make it hard to me for holding the concentration at a certin point for a large amount of time. I discovred recently that my own soundscapes I made myself helped me to not let the focus ran away from my current goal.

Yesterday I saw an article in the swedish television which wrote about an studie (from 2007), which proved that contigous sounds in low volume could help children to concentrate.  Off course, they said that wouldn't have headpones with only noise. I just discovred that my soundscape I produced could fill out the role as a concentration "point" for me. They create a power townwards this, a "gravitation" that prevents the focus to fly away and be captured by impulses from outside.

Normal music, such Pop and Rock can thoughly do the reverse, because it iself could be a own point for focus, but the solid sounds can solely work as a "focus magnet" and help me to be concentrated.
