We all know at least a little about the effect sound waves can have on the both the body and the mind.
You dont need to be a scientist to understand the way pleasant sounds make us feel, physically and metaphysically. We’ve all been moved by a wonderful piece of music. We all know how pleasant certain sounds can be – like the sound of falling rain or ocean waves – and what a profound effect they can have on our consciousness. There are, of course, scientific reasons behind these effects. Once they’re understood, it’s possible to reproduce them and put their wonderful power to use.
Our brain’s chemistry & electrical activity is responsible for more things than we can imagine, from consciousness, to intelligence, to overall health.
We live in a time where science is better understanding the mind/body link, leading us to a variety of solutions that we can use to optimize ourselves. One of the most interesting and effective is known as brainwave entrainment. Today, it is possible to use sound waves to modify, regulate, and improve one’s brain chemistry by safely and beneficialy moving the brainwaves into desirable patterns. Sound wave therapy has been proven by countless scientific studies to significantly reduce stress, improve memory, promote optimal health, boost mood, optimize brain function, & much more.
Here we will look at three of the most popular entrainment sound wave forms: binaural beats, monaural tones, and isochronic tones:
First discovered by physicist Heinrich Wilhelm Dove in the mid 20th century, binaural beats are responses within the superior olivary nucleus of each brain hemisphere to precisely measured sound tones. Today, binaural beats are used to stimulate positive mental states for all kinds of benefits such as meditation, relaxation, sleep, focus, increased creativity and much more.
How do binaural beats work?
Two separate tones will be presented to each ear, the brainwave patterns will then passively mimic the difference between these tones. For instance, if 150 Hz is played in the right ear, and 155 Hz to the left ear, the difference between these tones will be experienced (5 Hz) as a very relaxing theta wave, and the user’s consciousness will move into that particular brainwave state, entraining neural rhythms via what scientists call frequency-following-response (FFR).
Isn’t human hearing limited to 20-20,000Hz?
The binaural beat is not heard as immediate sound because the human audible range is limited to 20-20,000Hz. In plain terms, when two precise sounds of distinct frequencies are introduced separately to the ears, the brain produces low-frequency vibrations as a result, below the hearing threshold minimum, entraining the brainwaves of the user.
Today, binaural beats are used as a therapy to create very positive effects for the user, with great implications for an increased quality of life.
The second type of sound wave is known as a monaural beat.
Monaural beats are combined into one sound before they actually reach the human ear, as opposed to formulated in part by the brain itself, which occurs with a binaural beat. In order for the brain to hear and interpret monaural tones, the different elements involved must be of the same frequency (for instance 85Hz in your left ear & 85 Hz in your right ear). Monaural tones most often occur in nature and form the basis for musical chords. Binaural tones, on the other hand, usually come from man-made objects that produce noise, such as engines. Although both types of tone are thought to be effective in entrainment therapy, monaural is a bit more flexible in that it doesn’t require the use of headphones in order to be effective.
There is also a third type of tone that exists, known as the isochronic tone.
Isochronic tones are similar to monaural tones in that they are combined into a cohesive listening experience before they reach the ear. However, with isochronic tones, the tones themselves are switched on and off via predictable patterns, creating a pulse effect that is extremely effective when used for therapeutic reasons. It is this enhanced effect that make isochronic sound quite possibly, as some believe, the most effective type of beat in brainwave entrainment.
Which Type Is Most Effective?
Studies that have compared the effectiveness of binaural beats, isochronic tones, and monaural tones generally agree that each have their advantages & disadvantages. For this reason, Brainwave Wizard tracks combine all 3 entrainment types, in the most effective fashion possible.
