Your left ear hears the carrier frequency and your right ear hears it plus the beat amount. The brain perceives the difference as a slow pulsing, for example 200 and 210 Hz create a 10 Hz pulse. This only works with headphones, since speakers mix both tones before they reach your ears.
Delta (2 Hz) is linked with deep sleep, theta (6 Hz) with meditation, alpha (10 Hz) with relaxed wakefulness, beta (20 Hz) with active focus, and gamma (40 Hz) with high alertness. Effects vary person to person; treat it as ambiance, not therapy.
