Definitions
- the invention relates generally to hearing aid technology and in particular to a cover or protective cover for hearing aids or parts thereof, hearing aids provided with a cover or parts thereof and a hearing test device using the aforementioned hearing aids, and a method for operating this hearing test device.
- Hearing aids that are inserted into the ear canal and fixed there (concha devices, ITE devices) and parts of BTE devices that protrude into the ear canal are exposed to aggressive body fluids and cerumen. This generally leads to hygiene problems and the risk of ignition if these parts are not cleaned regularly. In ITE devices there is also the risk that the aggressive body fluids or cleaning fluids render the sensitive electronic and acoustic components inoperable.
- BTE devices behind-the-ear device
- ITE devices in the ear device
- ITE devices in the ear device
- Both BTE devices are the actual part of the hearing aid with electronics, microphone, handset, battery, control elements etc. in a common housing behind the ear and a so-called standard tube or a so-called Libby horn leads from the handset into the ear canal.
- ITE devices which have arisen in the course of miniaturization of electronic and electro-mechanical components, the hearing aid is completely in the auditory canal or protrudes from it into the auricle.
- ITE or in-the-ear hearing aids are sold, for example, by Siemens under the name Cosmea Top.
- the part of the hearing aid located in the ear canal or in the pinna is surrounded by an otoplastic, which is adapted to the individual ear shape or ear canal shape of the wearer and ensures that the hearing aid fits perfectly and functions properly (avoiding feedback, etc. ) enables.
- an otoplastic which is adapted to the individual ear shape or ear canal shape of the wearer and ensures that the hearing aid fits perfectly and functions properly (avoiding feedback, etc. ) enables. Examples of this are known from DE-OS 39 36 062 and DE-Gbm 91 15 511.8.
- German hearing aid G 90 03 269.1 discloses a hearing aid or otoplastic to be worn in the ear which has a ventilation channel which can be more or less blocked off by means of a locking device, as a result of which ventilation, voice modulation etc. during operation or can be influenced and changed while wearing.
- an ITE hearing aid which is surrounded by a sack or double sack-shaped cover.
- a hardenable material is introduced into the volume defined by the sleeve and the actual ITE device or by the interior of the double bag-shaped sleeve, whereby an individually adapted earmold is produced and the ITE device is thus fixed in the ear of the wearer.
- a disadvantage of this known ITE device is that the receiver or the sound exit channel of the hearing device only after the hardenable mass has hardened, ie. H. after the adaptation of the otoplastic, is released by cutting off the part which closes the sound outlet channel of the receiver.
- the earmold or the hearing aid can therefore only be tested when the earmold has already been manufactured. If the hearing aid provided with the individual otoplastic is not suitable for any reason or if the otoplastic produced has errors, a new hearing aid module must be used. There is therefore a risk that several hearing aid modules are "used up” before a suitable hearing aid module has been found.
- the individual adaptation of this hearing aid according to the prior art is therefore in no way inexpensive, on the contrary it is very cost-intensive.
- an optimally adapted hearing aid is selected for a patient suffering from hearing loss or can be made, the degree of his hearing loss or his hearing must first be determined. Once this has been established, an appropriate hearing aid can be selected and an otoplastic can be individually made for this.
- the conventional known hearing tests are very complex because they can only be carried out by trained specialists.
- a hearing test device is known from the document FR 2 664 494 AI, by means of which sound events stored on a sound storage device can be called up via a loudspeaker.
- the degree of recognition of the different sound events (curve b in FIG. 2) is recorded by an examining person for different hearing aids or for a hearing device with different settings. In this way, a correspondingly individually adapted hearing aid is selected through cooperation between the patient and the examining person. It is disadvantageous here that the examination can only be carried out with the constant participation of appropriately trained specialist personnel. Due to the high personnel costs, the examination procedure is becoming more expensive.
- Hearing aids are known from DE-OS 39 00 588 and DE-OS 32 05 685, in which certain acoustic operating parameters can be varied.
- Another object of the invention is to provide an improved protective device for hearing aids. It is also an object of the invention to provide a fast and efficient method for the individual selection and adaptation of a hearing aid in cases of mild to moderate hearing loss.
- Another object of the present invention is to provide a device for testing the hearing ability of a patient and for selecting an individually adapted hearing device, which allows a less cost-intensive application.
- Another object of the invention is to provide a correspondingly adapted method for testing the hearing ability of a patient and for selecting an individually adapted or coordinated hearing device.
- the protective cover according to the invention can be easily covered over the part of a hearing device to be inserted into the ear canal - above the otoplastic.
- the entire part located in the ear canal is thus covered by the liquid-tight, thin elastic sheath.
- the sound-permeable cap ensures that the acoustic properties of the hearing aid are not impaired.
- the protective cover is dimensioned so that it adheres securely to the relevant part of the hearing aid in a slightly stretched state due to the elasticity of the material. It can therefore be removed very easily; a time-consuming cleaning of the hearing aid itself is eliminated.
- the protective cover is very well suited as a disposable item.
- the thin, elastic material preferably a skin-friendly material, e.g. B. rubber, feels more pleasant and warmer on the skin than the hard plastic of conventional earmolds. Since the protective cover is worn over the otoplastic and thus lies directly against the skin of the ear canal, the protective cover according to the invention also improves the wearing comfort of hearing aids.
- a skin-friendly material e.g. B. rubber
- the protective cover is formed in one piece, which reliably prevents the penetration of liquids at the interface between the cap and the jacket.
- At least part of the cap is air-permeable, as a result of which the ventilation of the ear and the acoustic adjustment can be carried out in the usual way.
- This is achieved in a simple manner in that the cap is designed in the form of a grid, in particular in the form of a rubber grid.
- An advantageous embodiment ensures that the liquid-permeable rubber grille comes to lie isolated in the auditory canal, so to speak, and does not abut the skin of the auditory canal. This reduces the risk of liquid entering the grille.
- the auditory canal device as such or the part of a BTE hearing aid standard tube or Libbyhorn to be worn in the ear is surrounded by a tubular sheath, the cross section of which can be changed, it is possible to easily adapt standard hearing aids to the individual ear shape of a wearer .
- the tubular sheath exposes both the distal end of a hearing device facing the eardrum and the proximal end of a hearing device lying in the auricle (the distal end must be at least well permeable to sound).
- the cross-section of the tubular casing can be changed by mechanical or other means in such a way that it can be pressed onto the auditory canal and locked in this position.
- a double-tubular sheath which defines a cavity in which a fluid, in particular air, can be filled in via a closable opening.
- the filled fluid leads to an expansion and thus to an enlargement of the cross-section of the sheath, so that it adapts exactly to the ear canal and the concha.
- the tubular casing is pulled over a standard component that only roughly reflects the shape of the auditory canal.
- the standard component can be a conventional hearing aid module, which is connected to the custom-made otoplastic in conventional hearing aids.
- a ventilation channel is guided through the interior of the hearing device, in which the handset, electronics, microphone, etc. are arranged. The risk of functional impairment due to the moisture present in the ear is low, since the individual functional elements can be sealed or encapsulated accordingly.
- a hearing aid can be adapted on site to the individual ear shape of a wearer and the degree of hearing loss. Taking a cast and making an otoplastic in an external laboratory is no longer necessary. By filling the double-tube-shaped sheath on site, the individual earmold is produced immediately when the suitable hearing aid is selected.
- a hearing test device with which different sound or sound events can be called up from a sound storage device and made audible via a loudspeaker device is particularly suitable for the selection of a suitable hearing device.
- the acoustic operating parameters of a hearing device can be varied via a control and operating device until a hearing device optimally matched to the patient is found.
- the patient can freely select the various acoustic parameters, such as frequency response, amplification, output sound pressure level and also type of amplifier circuit, within certain limits, in order to find the most suitable hearing aid for him without outside help.
- the associated meaning is called up simultaneously with a specific sound event either in the form of an announcement text or in the form of a graphic representation from the sound storage device and displayed in a display device.
- a specific sound event either in the form of an announcement text or in the form of a graphic representation from the sound storage device and displayed in a display device.
- the sound event is a spoken text
- this spoken text is shown on the display device.
- the sound event itself and the associated meaning in the form of a text, a graphic representation, etc. are stored together in the sound storage device. Any sound events can thus be selected and the patient or a caregiver need not worry about the assignment of acoustically occurring sound events and the display of the associated meaning. The sound events can be repeated often.
- the standard shell of the hearing device has an elastic cover which can be replaced for hygienic reasons.
- this sheath is a tubular or double-tubular sheath into which a fluid, in particular air, can be filled, so that the hearing aid is then optimally adapted to the ear canal of the respective patient.
- a fluid in particular air
- hearing aids with a case are particularly suitable for this.
- Any hearing aid or hearing amplifier can be used as a hearing aid.
- the hearing aid is preferably attached to a carrying device, for example a stetho clip.
- the hearing aid can be controlled and operated via a cable connecting the hearing aid and the control and operating device or also by means of infrared rays or the like.
- various sounds such as. B. Newspaper rustling or alarm clock ringing can also be generated naturally, d. H. these clan events are not retrieved from the sound storage device, but are generated directly by the patient himself.
- critical parameters such as B. freely select the gain or the output sound pressure level of the hearing aid only in areas below the hearing impairment limit. If values outside these limits are necessary, these can of course be set by a corresponding specialist.

- a hearing aid with a double tube-shaped sheath is first inserted and air is blown into the sheath so that the sheath clings closely to the ear canal and the concha. The acoustic characteristics are then determined and a hearing device optimally adapted to the respective hearing ability is selected.
- ITE devices the front panel is also individually adapted. Finally, the air is extracted from the double-tube-shaped shell and a quick-curing plastic compound is filled in instead.
- FIG. 15 schematically shows an exemplary embodiment of the hearing test device according to the present invention.

- the test hearing aid 10 comprises a stetho clip 12 to which a hearing aid module 11 is attached.
- the hearing aid module 11 is via a
- Standard hose 14 with a standard shell 16 connected which is inserted into the patient's ear canal.
- the standard shell 16 is surrounded by a double-tubular, elastic cover 18 made of skin-friendly material.
- various amplifier circuits such as AGCI, AGCO, PC, KAMP circuits etc. can be represented or implemented.
- the electronics that implement these different types of amplifiers can either be accommodated in the hearing aid module 11 itself or externally, for example in the control and operating device.
- the patient or user of the hearing device receives the stetho clip with the hearing aid module 11.
- the standard shell 14 of the hearing aid 10 with the sleeve 16 is inserted into the auditory canal and air is introduced into the sleeve 18 via a valve (not shown) in the sleeve 18 blown in so that the sheath 18 clings closely to the patient's ear canal. In this way, the ear canal is sealed and feedback is avoided.
- Set the operating parameters of the test hearing aids ie he can, for example, change the gain in 5 to 10 dB steps in the range from 15 to 60 dB and he can vary the frequency response in a range from 100 to 6000 Hz (for broadband listeners in the range between 20 and 20,000 Hz), with both broadband transmission as well as selective transmission of different narrower frequency ranges is possible.
- the patient can call up various sounds or sound events known to him from the sound storage device 4, the meaning or pictorial representation of which is shown in the display device 6 and at the same time is acoustically emitted by the loudspeakers 8 and 9. Due to the optical display or representation of the respective sounding sound product in the display device 6, the patient knows exactly which sound event is currently sounding or sounding, and thus also knows how such a sound event, such as. B. the sound of leaves should sound in the wind. He can therefore change the various operating parameters of the test device until he feels an optimal and natural sound impression according to his subjective feeling.
- Speech comprehension is tested by retrieving a sound event that represents spoken text. It may make sense not to indicate the meaning of the text optically, since understanding language is less about the naturalness of the sound than it is about understanding it as such.
- the patient self-test it is of course advantageous if the patient is not completely free in the selection of the various parameters. Rather, it is also possible with the hearing test device according to the invention to execute certain preselected test patterns and to go through. That is, A "dialogue" arises between the hearing test device and the patient, in the course of which the patient can choose different alternatives. On the basis of the alternative chosen in each case, the test program then decides how the test program is to be continued and with which amplifier circuits or with which hearing aid types should be continued. With such a program-controlled self-test, the patient will primarily be able to freely determine the degree of amplification, ie the volume, while the other operating parameters of the hearing aid are selected in a program-controlled manner. Of course, it also makes sense that trained personnel are available at all times to answer questions from the patient.
- the patient can be adapted on site to the patient's individual auditory canal by letting the air out of the double-tube-shaped sheath 18 and instead filling in a fast-curing plastic compound.
- the patient's chewing movements optimize the fit of the hearing aid or the standard shell in the ear canal.
- the patient's individually adapted hearing aid i. H. that is, a hearing aid without a connection to the actual hearing test device can be tested again by calling up different sound events.
- two or more spatially separated loudspeakers are preferably used in order to also test the patient's directional hearing or to be able to select an optimal hearing device for this. It is of course also possible for the different sound events to be generated using headphones. Both analog sound memories, such as tapes, etc., and digital memories, such as CDs or, for example, PCMCIA memory cards, can be used for the sound storage devices.
- the control and operating device can, in particular, be a standard PC with appropriately configured peripheral devices.
- the peripheral devices would in particular include a so-called sound card, with which digitally stored sound events can be converted into corresponding analog electrical signals, which then sound as sound in the loudspeaker device.
- the use of a PC as a control and operating device also has the advantage that different test programs can be run in a simple manner, namely by software. For such test programs, it is also possible to use adaptive neural networks that adapt themselves to the respective patient.
