how to use 40hz sound for learning

To use 40Hz binaural beats for learning, you can follow the guidance provided by Andrew Huberman:

1. Find a source of 40Hz binaural beats, which can be found in various apps or YouTube scripts, often at no cost.
2. Use headphones for the best effect, as binaural beats work by providing slightly different frequencies to each ear.
3. Before starting cognitive work, listening to 40Hz binaural beats for about five minutes can enhance focus and concentration. Sometimes, Dr. Huberman uses them right before weight workouts to focus on contracting specific muscles.
4. You may also experiment with using 40Hz binaural beats during cognitive tasks if you find yourself highly distractible.
5. However, avoid using 40Hz binaural beats continuously while working, as it could be less effective or you might habituate to the stimulus.

In various studies, such beats have shown to improve performance on working memory tasks, possibly by impacting dopamine and acetylcholine levels, which are associated with focus and attention. The right dose and conditions will likely vary individually, so you may need to try different approaches to find what works best for you 1 2 3.
