According tomedia Slash Gear, double-earbeatbeats have been popular for nearly a decade. Thousands of videos can be easily found online that show these tones at different frequencies and claim to improve vibration, improve mood and improve memory. While past studies have found that listening to these beats may bring small benefits, a new study has found that improving mood is not one of them.
The two-ear beat describes an audio illusion in which two different beats are played, with the left and right ears receiving two slightly different tones at the same time to produce the illusion of a third sound. This can be used to produce different frequencies, with the idea that they will synchronize the listener’s brain waves and thus alter their moods and trigger a variety of unique and desirable psychological experiences.
Past studies of double-ear beats have been mixed. Some studies have found that certain beats improve a person’s concentration or memory, while others suggest that these beats are not beneficial. Many people are particularly interested in whether these beats can improve their mood, triggering mysterious experiences and other major events that some users claim to have experienced.
A recent study published in the journal eNeuro found that while the beats of both ears may improve attention and memory, they do not produce any mood changes. The findings contradict claims that some audio files may reduce anxiety, improve happiness and even more. The study, which involved both ear beats and single-ear beats, found that the latter were more effective at synchronizing brain activity.
The study found that the double-ear beats in particular synchronized “distant brain regions”, which may help some of the findings to improve concentration and memory. However, the findings suggest that people with some kind of emotional problem are better off seeking professional mental health help than relying on unproven theories.
