Embodiment approach

[0040] figure 2 A first embodiment is shown here, in which the external hearing prosthesis is positioned in the outer ear A. Such a positioning is suitable, for example, in the case of a patient who is completely deaf.

[0041] In contrast, image 3 On the one hand in position I is shown according to figure 2 This embodiment and, on the other hand, an embodiment with an external hearing prosthesis fastened to the outside of the ear is shown in position II for comparison. This positioning II can be suitable, for example, in the case of hearing difficulties or in the case of tinnitus. However, a non-invasive positioning is always achieved.

[0042] exist Figure 4 shown in the figure 2 , but additionally has an electronic control unit 9 and an energy supply unit 10 which, in the exemplary embodiment shown, is optionally formed by a solar cell. The electronic control unit 9 has a microphone 1 , an analog-to-digital converter 4 , a speech processor 5 , an encoder 6 and an ...

Abstract

The invention relates to a hearing prosthesis having at least one acoustic converter for converting acoustic signals into electrical signals, and comprising an ultrasound device by means of which a multiplicity of focused, pulsed ultrasonic beams can be generated, wherein the ultrasound device can be fixed in the outer ear and / or outside the ear, and wherein, on the basis of electrical signals generated by the acoustic converter, the ultrasonic beams can be focused on to various physically distributed points in a region of the inner ear or in a region of the auditory pathway in the brain, while stimulating nerves.

Description

technical field [0001] The invention relates to a hearing prosthesis and a method for compensating hearing loss or hearing impairment with such a hearing prosthesis. Background technique [0002] Against the background of the very large proportion of the population with hearing loss and because of the great toll this has on the affected population, there is a particular interest in hearing prostheses or hearing aids in practice. With intact hearing, the pinna collects sound waves from the environment and conducts them through the ear canal to the eardrum, which is excited to vibrate. The vibrations are transmitted through the middle ear to the fluid in the inner ear or cochlea. Through the movement of the fluid, the fine hair cells are deflected inside the cochlea and there trigger (bioelectric) nerve impulses, which are transmitted via the auditory nerve to the brain, so that auditory perception occurs in the auditory system. [0003] Conventional hearing aids operate ele...
