Brainwave entrainment refers to the process of synchronizing and aligning the brain's electrical activity with external stimuli, such as sound, light, or electromagnetic pulses, in order to induce specific mental states. The brain naturally produces electrical patterns known as brainwaves, which are categorized into different frequency bands, including delta, theta, alpha, beta, and gamma waves.

This process is based on the principle of frequency-following response, where the brain tends to synchronize its own electrical activity with external stimuli of a similar frequency.
Brainwave entrainment techniques are often used to promote relaxation, meditation, stress reduction, focus, and improved cognitive performance. For example, if a person wants to achieve a meditative state characterized by theta waves (4-8 Hz), they may listen to audio recordings or use devices that emit rhythmic sounds at that frequency. Over time, the brain tends to entrain to the external stimulus and starts producing brainwaves within the desired frequency range.
Common methods of brainwave entrainment include binaural beats, isochronic tones, monaural beats, and visual stimulation with flickering lights. Binaural beats involve listening to two slightly different frequencies in each ear, which the brain perceives as a beat that corresponds to the desired brainwave frequency. Isochronic tones are repetitive audio pulses with equal intervals, while monaural beats are created by mixing two frequencies before reaching the ear. Visual stimulation may involve watching a light source that flickers at the desired frequency.
It's important to note that brainwave entrainment is not a magical solution and its effects can vary among individuals. While some people report positive outcomes such as relaxation or enhanced focus, scientific research on brainwave entrainment is still evolving, and the extent of its benefits and effectiveness for different purposes is an area of ongoing study.
