15-Minute 40Hz Focus Reset | Binaural Beats to Start a Study Block

A 15-minute 40 Hz focus reset to start a study block. Headphones on. This is the short version, not the full sprint. 196 Hz left, 236 Hz right, brown-noise floor, volume about 30-40%. Use it to begin one task. When the block should run 90 minutes, switch to the long sprint linked below. A binaural beat only exists if each ear gets its own tone. Laptop speakers cancel it. The 40 Hz flicker studies in mice (Iaccarino et al., 2016) are not a test of this file. 00:00 - Start 03:00 - Stay on one task 12:00 - Wind down 90-minute sprint: Playlist:    • [40Hz GAMMA] Ultradian Focus Sprints   Citations: https://github.com/gitagent7/awesome-...
