Sound, explained honestly.

Sound Well is an evidence-based resource on how sound affects sleep, focus, learning, babies, older adults and pets. Every claim is graded 🟢 STRONG / 🟡 MODERATE / 🟠 WEAK / 🔴 ANECDOTAL and sourced to peer-reviewed research. No medical hype — we never say a sound "cures" anything.
