In his talk at EUHA 2017, Dr. Winfried Schlee of the Clinic for Psychiatry and Psychotherapy, University of Regensburg, Germany, explained the treatment of chronic tinnitus with Notched Auditory Stimulation, also known as Notch Therapy. Signia hearing aids are the only ones with in-built Notch Therapy, which can reduce the effects of tinnitus and may even make it disappear completely.*
Subjective tinnitus describes the conscious perception of a tone or swooshing sound with no corresponding external sound source. More than 70 million people across Europe are affected by tinnitus. Depending on their date of birth, between 5% and 20% of the population state that they continuously experience subjective tinnitus. Between 1% and 2% of the population are affected so heavily by tinnitus that they develop a sleep disorder, depression, concentration disorders, or anxiety.
Dr. Schlee explained that Notch Therapy represents a new method of tinnitus treatment. With Notch Therapy, the tinnitus frequency is precisely defined. Amplification of the frequency is then reduced so that it is integrated harmoniously into the overall background sound. By permanently relegating the tinnitus sounds into the background over a long period, the overstimulation is reduced and the brain ‘learns’ to no longer hear the tinnitus sounds, making life without tinnitus a real possibility.*
