Binaural beats and brainwave entrainment might sound like a Star Trek Discovery title episode. Moreover, using them for boosting productivity mind sound over the top. In reality, these concepts predate the first Star Trek. And while the so-called “mind-machines” were very popular in the 60’s, today everything is about boosting productivity.
As an illustration, consider this scenario. You’re at work and you need to be productive. Hence, you put some headphones on and play some sounds while working. In effect, your attention span increases. Meanwhile, your focus gets stronger, deeper. Moreover, the overall quality of your work improves. To say nothing of your mood. Subtly improved, your mood becomes work-positive. You end up doing more, faster, better.
