Definitions
- the invention relates to a hearing aid device with at least one acoustic sensor that converts ambient sounds and noises into electrical vibrations and at least one oscillating element that can be placed in or near the ear of a user for converting the electrical vibrations into acoustic waves.
- Hearing aid devices of the type mentioned are used in the prior art to make it easier for people who are hard of hearing to hear by converting ambient sound waves recorded via an acoustic sensor into electrical signals, which are then electronically amplified in a corresponding, in or near be converted back into acoustic waves by an oscillating element placed in the ear of a user concerned, with the intensity of the converted sound waves being higher as the intensity of the original sound waves picked up by the acoustic sensor.
- the known hearing aid devices all have the disadvantage that directional information of the sound waves impinging on the acoustic sensor is lost during conventional processing, so that a user of a conventional hearing aid device cannot distinguish between sound sources placed differently in the room can differ and therefore cannot concentrate on given sound sources.
- a user of a conventional hearing aid device hears a cacophony of noises, in particular noises that do not contain any desired information content.
- the object of the invention is therefore to create a hearing aid device that can be used to retain directional information from a number of different sound sources distributed in space around a user, so that the natural hearing properties of a functional human ear are largely retained.
- this object is achieved in that for the purpose of detecting directional information of different sound sources from the environment of a Users are provided with a plurality of acoustic sensors that can be placed at different points on or in the ear of a user, which, due to their individual placement, receive the sound waves from a respective sound source with a time offset and generate correspondingly time-offset electrical oscillations, with each of the acoustics Sensors is associated with an oscillating element and wherein the plurality of oscillating elements according to the time offset of the electrical oscillations mutually generate phase-shifted sound waves that interfere with each other produce a directional information of a j respective of the different sound sources.
- the hearing aid device is characterized by the combination of features that, for the purpose of detecting directional information of different sound sources from the environment of a user, a plurality of acoustic sensors that can be placed at different points on or in the ear of a user are provided, which due to their individual placement Receive sound waves from a respective sound source with a time offset and generate correspondingly time-offset electrical oscillations, with each of the acoustic sensors being assigned an oscillating element and the plurality of oscillating elements corresponding to the temporal Displacement of the electrical oscillations mutually generate phase-shifted sound waves that interfere with each other and generate directional information of a respective one of the different sound sources, achieves that a local filter function of the ambient sounds is largely made possible.
- a user of the hearing aid device is able to carry out a spatial, three-dimensional separation of a plurality of ambient noises and in this respect to concentrate on sounds that carry a desired information content.
- phase-shifted waves The generation of directional information by interference predetermined phase-shifted waves is, for example, from radar technology as a phased antenna or. English "phased array" known.
- At least three acoustic sensors and three uniquely assigned oscillating elements are provided.
- the hearing aid device contains a battery-operated electrical amplifier device whose intensity can be controlled, which amplifies the electrical oscillations supplied by the acoustic sensors to such an extent that the relevant ones are generated by the oscillating elements Sound waves can also be easily heard by users who are hard of hearing.
- the at least three oscillating elements and the amplifier device form an integral unit that can be placed inside the ear of a user.
- the acoustic sensors of the hearing aid device according to the invention can preferably be placed in the area of the auricle of a user.
- the acoustic sensors can be placed on the outside of a user's auricle, alternatively be placed on the inside of a user's auricle, and also alternatively be placed partly on the outside and partly on the inside of a user's auricle.
- the oscillating elements are aligned in the ear of a user in order to irradiate not only the eardrum but also other sound-sensitive areas in the inner ear of a user.
- each acoustic sensor is assigned two oscillating elements, with a first oscillating element being aligned with the eardrum of a user and a second oscillating element with another sound-sensitive element Area is aligned in the inner ear of a user.
- each acoustic sensor being uniquely assigned an oscillating element, and with three first relevant oscillating elements being aligned in the direction of the eardrum of a user, and three in each case second relevant oscillating elements are aligned in the direction of another sound-sensitive area in the inner ear of a user.
- An oscillating element of the hearing aid device according to the invention is preferably but not necessarily formed by a piezo crystal.
- Fig. 1 shows a preferred arrangement of the acoustic sensors of the hearing aid device according to the invention, in a plan view of an ear of a user
- Fig. 2 shows a preferred embodiment of a hearing aid device according to the invention placed in the external auditory canal of a user, in a cross-sectional view.
