90-Minute Deep Work Sprint | 40Hz Gamma Binaural Beats for Focus

A 90-minute deep work sprint with 40 Hz gamma binaural beats for focus and studying. Headphones on. One task for the whole block. The tones are 196 Hz in the left ear and 236 Hz in the right: a 40 Hz difference centered on 216 Hz, over a brown-noise floor. Volume about 30-40%. The 15-minute version is the warm-up if you want to sample the sound first. A 40 Hz auditory steady-state response is well measured for clicking or amplitude-modulated sound (Ross et al., 2005). A binaural beat is a different stimulus: two steady tones, one in each ear. The MIT and Cell papers on 40 Hz gamma stimulation used light and sound flicker in mouse models of Alzheimer's disease (Iaccarino et al., 2016; Martorell et al., 2019). They did not test this headphone track, and this session is not a treatment for memory disease. 00:00 - Start the block 15:00 - Hold a single task 45:00 - Midpoint 1:15:00 - Close the sprint Papers: Ross, B., et al.
