Amplitude modulation is applied to the study music, replacing isochronic tones and binaural beats as an alternative mode of brainwave entrainment. Isochronic tones are a form of amplitude modulation, where the volume (amplitude) of a sine/triangle/saw wave fluctuates (modulates) between ‘on’ and ‘off’, producing a pulsing ‘beat’ frequency…
The difference with this audio however is that although the method is identical, the modulation is applied to the music itself rather than a separate tonal element as with isochronics. The term ‘Music Modulation’ therefore is used to define brainwave entrainment via music only, which some may find more soothing and less intrusive than isochronics.
The rate at which the volume modulates is measured in Hz. Different frequencies are associated with various states of consciousness.
The frequencies used here vary from 9.25hz to 16hz. The Beta frequencies (12 to 16hz) are conducive to focus and concentration over long periods of time, while the alpha waves (9.25 to 11.5hz) are interspersed throughout to prevent over-stimulation and ear fatigue. Alpha waves also aid with memorisation, creativity and stress relief.
The frequencies shift dynamically, ramping slowly back and forth between high alpha and low beta.
Unlike binaural beats, brainwave entrainment via Music Modulation does not require headphones, though the effect may be more pronounced through their use. Using a low, comfortable volume, try using both speakers and headphones and find what works best for you.
