Binaural Beats

Binaural beats are a form of music therapy, and they are an important foundation of sound healing. Also known as “brain wave entrainment,” binaural beats are at the heart of Biosound Therapy.

Binaural means “relating to both ears.” Brain wave entrainment involves playing a different tone in each ear. Each tone has a different frequency. For example, the tone playing in the left ear may be 200 Hz, and the tone playing in the right ear may be 210 Hz. The tones travel separately to the inferior colliculus, which is the part of the brain that handles auditory input. Once in the inferior colliculus, the two tones are married and produce a “beat” at a new frequency, which is the difference between the two incoming frequencies—in this case, the new frequency is 10 Hz.

The idea is that your brain syncs to the new frequency, putting you in a particular brain wave state. In the example above, binaural beats that produce a new brain wave frequency of 10 Hz will put your brain into the alpha state.

Binaural beats have been shown to reduce anxiety and stress and improve sleep. A study published in the journal Alternative Therapies in Health and Medicine found that listening to binaural beats five times a week for four weeks significantly reduced anxiety in mildly anxious participants. Another study, published in the European Journal of Sports Science, found that brain wave entrainment significantly improved sleep quality and the post-sleep state in athletes. Brain wave entrainment has also been shown to reduce pain and improve behavioral problems in children.

Biosound Therapy utilizes binaural beats to produce a theta brain wave state.
