Binaural beats are an auditory illusion created when two slightly different frequencies are played in each ear. The brain perceives a third tone, which is the difference between the two frequencies. For example, if one ear hears a sound at 300 Hz and the other at 310 Hz, the brain interprets a beat at 10 Hz. This phenomenon can influence brainwave activity and is often used for relaxation, meditation, and focus. Many people use binaural beats in conjunction with meditation or mindfulness practices to enhance their experience. Research suggests that listening to these beats may help reduce anxiety, improve sleep quality, and increase concentration. However, individual responses can vary, and more studies are needed to fully understand their effects.
