Problems solved by technology

Hearing aids have many problems: acoustic feedback (because the amplifier is very close to the speaker), insufficient sound quality, and discomfort due to obstruction of the ear canal
However, its problems are: high power consumption, signal variation, and background noise
Also, magnetic resonance imaging (MRI) compatibility with some components is an issue

Embodiment Construction

[0030] figure 1 The relative positions of the external auditory canal module 1 and the ear implant 20 are schematically shown. It can be seen that the ear module 1 is located in the ear canal 3 . The ear module 1 has a channel 5 passing through the module 1 in order to prevent blockage of the ear canal 3 . A modulated infrared (IR) light signal, represented by dashed line 7 , is emitted by a light emitting diode (LED) 9 and passes through the eardrum 11 to be detected by the implant 20 . In this embodiment, the implant 20 is located at the anvil stirrup point so as to vibrate the stapes, although the implant could be located elsewhere, such as in the carina.

[0031] figure 2 The components of the inventive ear module 1 and implant 20 are shown in more detail. The ear module 1 comprises a loudspeaker 1 and associated electronic circuitry 13 for converting sound into an electrical signal, which in turn is converted by an LED 9 into a modulated light signal 7 (as shown by t...

Abstract

The present invention relates to a hearing aid system comprising a hearing implant and a method of powering a hearing implant, the system comprising an external ear canal module and an implant, wherein the signalling and / or powering of the ear implant is by way of a light signal being provided to the implant through the ear drum from, for example, the ear canal module.

Description

technical field [0001] The present invention relates to a hearing aid system comprising a hearing implant and a method of supplying power to the hearing implant. Background technique [0002] Sensorineural deafness is by far the most common type of hearing loss. Deafness affects 9 million people in the UK, approximately 95% of whom have sensorineural deafness (source failure deafness, UK). Causes include congenital, bacterial, high-intensity noise, and especially the aging process, with 30% of those affected being over 60 years old. Hearing impairment is the third most prevalent chronic problem affecting the aging population - and the least diagnosed. There is also an increased incidence of hearing loss among younger age groups due to exposure to loud noise. [0003] Currently, there are no effective means of repairing the cochlea or the neural pathways to the brain. For most patients, hearing can be adequately restored by amplifying the sound sufficiently with hearing a...
