Yes, it is an established fact that you do not need to have intact hearing in order to benefit from Hemi-Sync products. Both experts and individuals with hearing impairments report that the frequencies in the binaural beats can reach the brain through the movements of bones inside the ear. There are three small bones in the ear canal that vibrate when the audio plays. This vibration transfers from the outer ear all the way to the inner ear. As a result, the frequencies are effectively carried to the brain.
