Dr Kovac investigated whether listening to binaural beats during high-concentration tasks reduces the number of programming errors made by software developers. He recorded the total number of syntax errors made by two separate groups of developers over a three-week period. The developers who listened to binaural beats had a mean of 4.2 errors, whereas the developers who worked in silence had a mean of 8.7 errors.
