Another sound that can alter brainwave patterns and induce states of relaxation and focus is something called binaural beats. Binaural beats is an auditory phenomenon that occurs when 2 tones of different frequencies, which are presented separately in each ear, elicit the sensation of a 3rd tone oscillating at the difference frequency of those 2 tones. A recent study investigated the effects of binaural beats on cognitive function and mood. The researchers found that exposure to binaural beats resulted in improvements in both cognitive performance and mood state. Specifically, participants reported feeling more relaxed and focused after listening to binaural beats, suggesting that they could have beneficial effects on your mental well-being.
