Binaural beats are a fascinating audio phenomenon created when two tones of slightly different frequencies are played in each ear. The brain perceives a third tone—the difference between the two frequencies—and this is called the binaural beat. For example, if a tone of 200 Hz is played in one ear and 210 Hz in the other, the brain "hears" a 10 Hz beat. To experience binaural beats, you need headphones to ensure each ear receives the correct frequency.

These beats are often used as a tool for relaxation, meditation, focus, and sleep improvement. They are believed to influence brainwave activity, as the frequency of the binaural beat corresponds to specific brainwave states. For example:

• Delta waves (0.5-4 Hz): Promote deep sleep and relaxation.
• Theta waves (4-8 Hz): Associated with meditation, creativity, and intuition.
• Alpha waves (8-14 Hz): Encourage relaxation and a calm, alert state.
• Beta waves (14-30 Hz): Enhance focus, problem-solving, and energy.

Many people use binaural beats to reduce stress, improve focus during work, or enhance meditation practices. While some scientific evidence supports their effects, much of their impact is subjective, making them a unique tool for personal well-being and mindfulness.
