Isochronic tones or pulses create pulsating beats that create a singular tone. Isochronic tones encourage brainwave frequencies to fall
into step with a frequency corresponding to the intended brain-state. Isochronic tones work by emitting sound at regular intervals: Regarded as the most effective tone-based brain entrainment method.
Isochronic tones are regular beats of a single tone used for brainwave entrainment. Similar to monaural beats, the interference pattern that produces the beat is outside the brain so headphones are not required for entrainment to be effective.
The contrast between noise and silence is more pronounced than the constant pulses of monaural beats, the stimulus is stronger and has a greater effect on brain entrainment.
Isochronic tones work by emitting sound at regular intervals. This excites the thalamus and causes the brain to duplicate the frequency of the Isochronic tones, changing its thought patterns.
