Do you have problems from anxiety, depression or sleep problems?

Would you be open to listening to a special type of sound or music? It turns out that a special type of sound known as binaural beats may be able to help your brain.

What are Binaural Beats?

Binaural beats is when your brain hears two different tones in each ear, that are a different frequency. For example, if you are hearing a sound that is at a frequency of 132 Hz in the left ear, and a tone that is 121 Hz in the right ear, then your brain will fall into synchrony with the difference, which is 132 Hz minus 121 Hz = 11 Hz. Your brain will hear a tone at 11 Hz (in addition to the two tones in each ear). It is an “auditory illusion”.

Binaural beats require that: 

  • The two tones have frequencies less than 1000 Hz
  • The difference between the tones can’t be more than 30 Hz
  • The tones must be listened to separately through each ear.

What Might It Help With?

Some studies suggest that binaural beats might be helpful for:

  • Sleep (Abeln, 2014)
  • Anxiety (Le Scouarnec, 2001)
  • Chronic pain (Zampi, 2016)
  • Tinnitus (David, 2010)
  • Stress
  • Relaxation
  • Creativity

How Do I Get Started?

To try binaural beats, you will need:

  • Stereo headphones
  • Computer, mp3 player or cellphone to play the music

What Frequency to Use?

Cerebral activity as recorded by EEG is typically divided into four categories:

Name of pattern



1. Beta

14 Hz to > 100 Hz.

Normal waking consciousness
Associated with concentration, alertness, arousal and cognition. At higher levels, associated with anxiety.

Listening to beta waves is felt to help with improving creativity, concentration

2. Delta

0.1–4 Hz

Associated with dreamless sleep

Listening to delta waves is felt to help with sleep

3. Theta

4–8 Hz

Random eye movement (REM) sleep, meditation and creativity

Listening to theta waves is felt to help with sleep

4. Alpha

8-13 Hz


Listening to alpha waves is felt to help with relaxation

Through brain entrainment, different frequency binaural beats can thus theoretically encourage different brain patterns.

For example, a 10 Hz binaural beat would encourage the brain to produce a 10 Hz beat corresponding to a relaxed (alpha) state of consciousness.

Advantages and Disadvantages of Binaural Beats

Advantages of Binaural Beats

  • Compared to psychotherapy and medications, binaural beats is much less expensive and does not have any significant side effects.


  • The main drawback to binaural beats is that there is less evidence.

In summary, however, given how inexpensive it is to try binaural beats (i.e. all you need are headphones and a cellphone or internet), it is reasonable to try if it might be helpful for one's problems with sleep, anxiety and stress.
