Closed Loop Acoustic Stimulation: The Key to Better Sleep and Work Performance
Closed loop acoustic stimulation, a wearable sleep-improvement device, can improve both sleep quality and work outcomes, according to a study published in the Journal of Applied Psychology. The technique involves enhancing slow brain wave patterns during sleep using an algorithm that takes EEG data from a sleeping person and plans precisely timed auditory tones. The study found that closed loop acoustic stimulation improved slow-wave sleep and had a positive impact on engagement, performance, and citizenship behaviors at work the following day. However, the device tended to work better for younger employees and was relatively ineffective for older employees.
