how to use 40hz sound for learning

Try 40 Hz binaural beats as a brief lead-in to learning: listen for about five minutes before you begin, using headphones. Different frequencies are delivered to each ear, and the brain processes the difference between them. 1 2

• Find a track: Search a free app or online source for “40 Hz binaural beats.” Headphones are the typical way to hear the different frequencies in each ear. 3 4
• If you’re highly distractible: Try leaving the beats on during the learning session; otherwise, Huberman’s usual approach is to listen beforehand and turn them off for the work. 5
• Don’t default to continuous use: He advises against using them for every work bout, noting you may habituate to the sound. 6

In short, start with a short pre-learning listen, then adjust based on whether listening during the task helps you.
