This paper addresses the importance of steady-state brain oscillation for brain connectivity and cognition. Given that a healthy brain maintains particular levels of oscillatory activity, we argue that disturbances or dysrhythmias of this oscillatory activity coincide with common health conditions including Alzheimer’s disease (AD), Parkinson’s disease (PD), pain, and depression. This review shows that electric brain stimulation contributes to regulation of neural oscillatory activity and the alleviation of related health conditions. It is then argued that specific sound frequencies in their vibratory nature can serve as a means to brain stimulation through auditory and vibrotactile means and as such can entrain and regulate oscillatory activity. The frequencies employed and found effective in electric stimulation are reviewed with the intent of guiding the selection of sound frequencies for vibroacoustic stimulation in the treatment of AD, PD, pain, and depression.
