Isochronic tones

Isochronic tones are regular beats of a single tone that are used alongside monaural beats and binaural beats in the process called brainwave entrainment. At its simplest level, an isochronic tone is a tone that is being turned on and off rapidly. They create sharp, distinctive pulses of sound.
Isochronic tones are tones of any frequency that recur at regular intervals, usually rapid. Isochronic tones can quantitatively be distinguished by both the frequency or pitch of the tone itself, and by the interval or frequency of repetition of the tone.
While listening to isochronic tones is a technique often employed in the theoretical practice of brainwave entrainment, reliable scientific research into the effectiveness of this practice for health purposes is scant. A 2016 study led by MIT researcher Li-Huei Tsai however, has lent the practice a measure of credibility, when researches demonstrated that auditory and visual oscillations, in the form of 40hz clicks and a 40hz flickering light, reduced levels of amyloid-beta and tau proteins, prevented neuron death, and preserved synapses and sustained learning and memory in a variety of Alzheimer’s disease mouse models.[1][2][3]
