Definitions

  • the invention relates to an audiological transmission system adapted to be worn on, in or behind the human ear and having at least a housing, an electrical amplifier, a speaker and an output channel for acoustic signals to the ear.
  • Audiological devices of the generic type are known in many ways. Such devices are commonly referred to as “hearing aids.” They are designed to enhance the hearing of a person suffering from hearing loss by acoustically amplifying sound to a sound level suitable for the person wearing the device, such as amplifying the spoken word electronically The amplified signal is delivered to the deaf person's ear, which is thus able to hear better again.Furthermore, various algorithms, most of which are implemented by a microprocessor, implement functions such as hiding environmental or noise interference.
  • tinnitus maskers or “tinnitus noisers” or “tinnitus instruments”
  • ear noises such as sounds, sounds or other acoustic qualities Affected “Hears”, but whose creation is not based on any real source of sound, it is also called “phantom noise”.
  • phantom noise For relief, a device is worn behind, on or in the ear, which produces sounds or sounds of certain acoustic qualities and delivers them to the ear.
  • a “noise generator” should cover the phantom noise and thus make more bearable.
  • transcutaneous nerve stimulation devices have become known which influence the neuroelectric quality and thus the function of the nerves to be stimulated by invasive or non-invasive electrical stimulation of nerves.
  • the goal of this approach is usually to cause psycho-vegetative changes, such as stress reduction, or to treat neuropsychiatric disorders.
  • Hearing disorders are often associated with psychosomatic disorders such as depressive moods, depression, sleep disorders and others.
  • vagus nerve stimulation has been successful in recent years in the treatment of depression.
  • the patient becomes neurosurgically in the left neck area Stimulator implanted, which generates current pulses and thus leads to a change in the neurophysiological quality of the vagus nerve.
  • Vagus nerve stimulation as shown in numerous studies, has positive effects on clinical pictures such as epilepsy and depression.
  • Implantological stimulation has proved disadvantageous in many respects. These are, in particular, the surgical risk associated with the invasive introduction, the danger of a nerve injury and a risk of infection associated with the procedure. In addition, the patients experience a feeling of being "externally controlled.” The high costs for such a stimulator or for the surgical intervention and the necessary infrastructure are also worth mentioning.
