What are binaural beats and how do they work?

Binaural beats are an auditory illusion created when two slightly different frequencies are played in each ear. Your brain perceives a third tone equal to the difference between the two frequencies. For example, if 200 Hz is played in the left ear and 210 Hz in the right ear, your brain perceives a 10 Hz beat. This phenomenon can influence brainwave patterns and mental states.

Do I need headphones to use binaural beats?

Yes, headphones or earbuds are essential for binaural beats to work properly. Each ear must receive a different frequency independently. Speakers or single-ear listening will not produce the binaural beat effect.

What are the different brainwave frequencies used for?

Delta waves (0.5-4 Hz) promote deep sleep and healing. Theta waves (4-8 Hz) support meditation and creativity. Alpha waves (8-14 Hz) encourage relaxation and stress relief. Beta waves (14-30 Hz) enhance focus and alertness. Gamma waves (30-100 Hz) may improve concentration and cognitive function. Each frequency range is associated with different mental states.

Is this binaural beat generator free to use?

Yes! This is a completely free tool with no subscriptions, no registration required, and no hidden costs. All features including presets, custom frequencies, visualization, and session timers are available at no charge.

How long should I listen to binaural beats?

Session length varies by purpose. For meditation or relaxation, 15-30 minutes is common. For focus sessions, 30-60 minutes works well. For sleep induction, you can listen as you drift off. Start with shorter sessions (10-15 minutes) if you're new to binaural beats and gradually increase duration as comfortable.
