Pure tones played together interfere with each other when they are close in pitch but not identical.
When each tone is sent to a different ear, there will not be any physical interaction between the waves,
yet your brain still creates an interference inside your head: the so-called binaural beat.
In order to create a binaural beat, each ear must receive its dedicated signal.
Therefore, binaural beats only work through headphones.
Most binaural beat generators on the Internet use two carriers:
one for each ear. We use 10 of them instead, creating the most complex beating patterns ever produced online!
We also use the purest sine waves generated from a professional test tone generator,
ensuring the clearest and deepest beats.
Activating the motion feature ever-changes the beating patterns, entraining various brainwaves frequencies one after the other.
Have a try!
myNoise.net provides two binaural beat players. The carriers on this one have been set to harmonic frequencies and produce pure binaural beats.
Brain Waves (brainwaves) Entrainment
Brainwaves are electrical activity patterns caused by the neurons of the brain communicating with each other. Brainwaves can be detected using sensitive medical equipment such as an EEG. They provide an indication of the mental state of an individual.
Brainwaves are divided into four main categories:
the Delta waves, when deep sleep occurs;
the Theta waves, associated with a state of somnolence and reduced consciousness;
the Alpha waves, when we are in a state of physical and mental relaxation;
and the Beta waves, emitted when we are consciously alert, or when we feel agitated or tense.
Brainwave frequencies are in the range of 0.1 to 4 (Delta), 4 to 7 (Theta), 7 to 13 (Alpha) and 13 to 30 (Beta) cycles per second (Hz).
Brainwave entrainement (or synchronization), aims to cause our brainwave frequencies to fall into step with a periodic stimulus having a frequency corresponding to the intended brain-state. This can be used, for example, to induce sleep. This page uses binaural beats as auditory stimuli.
