The Dutch University of Delft is starting with a research group that is setting up research of electronics that can give healing pulses to the body to treat Parkinson's and also Tinnitus. I only have 1 pdf files but I'm searching for them. First information starting at page 25. So there is objective measurement of tinnitus in stead of subjective measurement. http://bioelectronics.tudelft.nl/shared/BE/Description/WIMDs_DL_complete_2014_Serdijn.pdf Professor De Ridder who is well known in Tinnitus Research gives a presentation too. Bio electronics / electro physiology is what the research field is called.
