40Hz Sound Therapy

If you do not hear the 40Hz sound:
1. Make sure that the 40Hz Sound Therapy is on in the global app Settings (the Settings button is in the top left corner of the home screen).
2. Set iPad sound volume to maximum
3. Use over-the-ear headphones
4. 40Hz Sound plays only during cognitive games
5. Un-mute the iPad speakers: swipe up from the bottom of the screen to open the Control Center. Tap on the bell icon to turn it on – it should become white.
