For more complexity, modulation is applied to the mid-alpha tone. Wave Pattern II: Helps alleviating headaches with steady low theta (5Hz) and mid-beta (10Hz) tones. For additional complexity, circular modulation is applied to the mid-beta tone. Wave Pattern III: Helps alleviating headaches with mix of varying low theta (5Hz) and mid-alpha (10Hz) tones. Modulation is applied to the mid-beta tone and the background noise smooths is varied.
