Backed by research

Calm, told honestly

Sound can genuinely help you relax, sleep and concentrate. A lot of what gets said about “healing frequencies” is folklore, though, and some of it is plainly wrong. So every sound here carries two short notes side by side: what research actually supports, and what tradition claims. You get the calm and the truth, not a sales pitch.
