"A study of 5000 patients showed that high-dose, cold laser light can improve such hearing problems as tinnitus, oversensitive hearing, ear pressure, vertigo, and even hearing loss.4 Lutz Wilden, a medical doctor and LLLT specialist practicing in Germany (www.dr-wilden.de), said the study revealed that LLLT improved hearing loss by 20% on average, with younger patients showing improvement up to 25 decibels or 50%.
The study showed that wavelengths between 630 and 830 nm excited the production of adenosine triphosphate (ATP), which is produced by cell mitochondria, causing natural and accelerated regeneration of hearing cells."
