Common questions
What is sound therapy?
Sound therapy means using specific kinds of audio, such as steady noise, calming music, or binaural beats, to support relaxation, sleep, and focus. Some uses have promising research behind them and others rest mostly on tradition. Every guide on this site tells you which is which.
Is it safe to listen to sound therapy every day?
For most people, yes. Keep the volume low enough that you could still hear someone talking to you, and stop if a sound makes you uncomfortable. If you have epilepsy or a seizure disorder, ask a doctor before using audio designed to affect brain rhythms. Nothing on this site is medical treatment.
Do I need headphones for binaural beats?
Yes. Binaural beats only happen when each ear hears its own tone, which is what stereo headphones or earbuds do. Any working stereo pair produces the effect. Price and style are a comfort choice, not an effect choice.
