Abstract

A sheath for hearing aids is disclosed, as well as hearing aids or parts of hearing aids provided therewith. The sheath is shaped as a tube or bag and is slipped on the hearing aid introduced into the auditory meatus (in the case of internal hearing aids) or on the part of the hearing aid introduced into the auditory meatus (in the case of external hearing aids). The tubular sheath has a variable diameter and thus closely conforms to the wall of the auditory meatus. The tubular sheath serves both to retain the hearing aid in the auditory meatus and to protect the hearing aid from cerumen, etc. Also disclosed is a hearing test device that allows in particular the above-mentioned hearing aids to be individually adapted to a user. With this hearing test device, various sounds or acoustic events may be reproduced or performed. The test person modifies the operational parameters of the hearing aid until an optimum acoustic impression results.

Description

Case for hearing aids, hearing aids provided therewith or parts thereof, and the hearing test device and method

The invention relates generally to hearing aids and more particularly to a sheath or protective cover for hearing devices or parts thereof, provided with a hearing aid shell or parts thereof, and a hearing test using the aforementioned hearing aid and a method of operation of this hearing test.

Hearing aids, which are inserted in the ear canal and there fi xed (Concha devices, ITE devices) and projecting into the ear canal Ge parts of BTE devices are exposed to body fluids and aggres¬ immersive earwax. This generally leads to hygiene problems and the risk of inflammation, if these parts are not cleaned regularly. In ITE, there is also the danger that the aggressive body fluids or liquids Reinigungs¬ make the sensitive electronic components and aku¬ stischen inoperable.

It is known to hen verse¬ with a Cerumenschutzgitter the end facing the tympanic membrane of ear devices or of the ear canal to load bearing parts of a hearing aid. While this prevents the penetration of cerumen, but not je¬ the penetration of body fluids.

In hearing aids or in hearing aids to compensate for Hör¬ weaken or hearing loss, a distinction is essentially two types of devices, so-called BTE devices (Behind-the-ear device) and so-called ITE devices (in the ear device). The latter are also called ear canal devices or concha hearing aids. In the BTE devices, the real part of the hearing aid is with electronics, microphone, receiver, Batterief ch, control elements etc. in a common housing behind the ear of the listener performs a so-called standard hose or a so-called Libby horn into the ear canal , In so-called ITE, which have arisen in the course of the miniaturization of electronic and electro-mechanical components, the hearing aid is completely in the canal and it sticks out of this in the ear. ITE or in-ear hearing aids are sold for example by the company. Siemens under the name Cosmea Top.

In both types of hearing aids which is in the ear canal or the part of the hearing aid located in the external ear surrounded by an ear mold that matched to the individual ear shape, or ear canal shape of the carrier and a perfect fit and a proper function of the hearing aid (prevention of feedback etc. ) allows. Examples of this are known from DE-OS 39 36 062 and DE-91 15 511. Gbm. 8

For individual adjustment of the frequency response for equalizing the pressure and the voice modulation in this specially finished ear devices also bores are made, which also serve to ventilate the Gehörgangε. uter from the German use G 90 03 269.1 is to be worn in the ear hearing aid or an ear mold is known which comprises a ventilation duct which may be more or less closed off by means of a locking device, whereby the ventilation, the voice modulation etc. during operation and can be influenced and varied during wear.

This Otoplaεtiken lead to a considerable increase in the cost of hearing aids, as they must be made individually. Also thereby, the purchase of a hearing aid to a very lengthy affair, with the result that hearing aids are often only be purchased if they are absolutely necessary, ie in case of severe hearing loss. People with mild to moderate hearing loss often refrain from cost, time and also for image reasons on the purchase of a hearing or an electronic hearing aid.

From the DE-Gbm 87 12 957.4 a-ear hearing aid is known which is surrounded by a blind or double sack-shaped envelope. In the method defined by the sheath and the actual ITE device or through the interior of the double sack-shaped envelope volume, a curable material is introduced, thereby producing an individually adapted ear device and thus the ITE device is fixed in the ear of the wearer. A disadvantage of this known ITE device is that the listener or the sound output channel deε hearing aid, ie freigeigt after adjusting the otoplasty, by cutting the occluding the sound output channel of the receiver member until after the hardening of the hardenable mass. In order for the ear device or the hearing aid can only be tested when the ear mold has already been made. Is that with the individual otoplastic hearing aid provided for some reason is not suitable or has the-made ear mold error is found, a new hearing aid module must be used. Thus, there is a risk that a plurality of hearing aid modules be "consumed" before a suitable hearing aid module has been found. The individual adaptation of this hearing aid according to the prior art is therefore not kostengünεtig but very expensive on the contrary.

So you can select an optimally adapted hearing aid for a patient suffering from hearing loss patients or manufactured, first the degree of hearing loss and his hearing must be determined. If this note can be selected an appropriate hearing aid then and earpiece are custom-made for this. The conventional known hearing tests are very expensive because they can only be performed by trained personnel. In addition, there is a disadvantage in that substantially unna¬ ral sine tones are used to test the Hörfähikgeit.

From the publication FR 2664494 Al a hearing test device is known, can be accessed through a speaker by means of the stored on a sound storage means sound events. The degree of recognition of the different sound events (curve b in Fig. 2) is recorded by a person under test for different hearing aids or for hearing aids with different settings. On dieεe, a correspondingly individually fitted hearing aid is selected through collaboration between patient and be examined person. The disadvantage here is that the investigation can be carried out only under constant participation by qualified skilled personnel. Due to the high labor costs, the investigation procedure therefore veteuert accordingly.

From DE-OS 39 00 588 or DE-OS 32 05 685 hearing aids are known, in which certain acoustic operating parameters can vary.

It is therefore an object of the present invention

A hearing aid or provide to be worn in the ear part of a hearing aid that can be readily adapted for particular shapes to medium hearing loss and faster and cheaper adapted to the individual characteristics of a wearer. It is another object of the invention to provide an improved protective device for hearing aids. It is another object of the invention in cases of slight to provide a rapid and efficient method for the individual selection and adaptation of a hearing device to medium hearing loss.

It is another object of the present invention to provide an apparatus for testing the hearing ability of a patient and for selection of an individually adapted hearing aid, which allows for a less costly application. It is another object of the invention to provide a correspondingly adapted method for testing the hearing of a patient and to choose a customizing or coordinated hearing aid available.

These objects are achieved by the features of claims 1, 9, 10, 32, 35, 38, 48 and 53rd

The protective casing of the invention can be easily over the to be inserted into the ear canal part of a hearing aid - about the otoplasty - coat. Thus, the entire part located in the auditory canal is covered by the liquid-tight, thin elastic sheath. By the sound-permeable cap is ensured that the acoustic properties of the hearing device are not impaired.

The protective sleeve is so dimensioned that it securely adheres to the relevant part of the hearing device in a slightly stretched state due to the elasticity of the material ,. thus it can also be very easily removed; an expensive purification of the hearing aid itself is eliminated. The protective sleeve is very well suited as a disposable item.

The thin, elastic material, preferably a skin-friendly material, for example. As rubber feels pleasant on the skin and warmer than the hard plastic of traditional ear molds. Since the protective sheath is worn over the ear mold and thus bears directly against the skin of the ear canal, the erfindungsge- Permitted protective cover also improves the comfort of hearing aids.

According to an advantageous further development of the invention, the protective sheath is integrally formed, thereby ensuring the penetration of liquids at the interface between the cap and shell is prevented.

According to a further advantageous development of the invention, a portion of the cap Er¬ is at least air-permeable, whereby the ventilation of the ear and the acoustic matching performed in the usual manner wer¬ the can. In a simple way this is achieved in that the cap is in the form of a grid, in particular in the form of a rubber lattice.

BTE device, etc. are influenced and individually adaptable to the voice modulation, feedback, ventilation of the auditory canal. With the embodiment of FIG. 6 matching components are provided with the same reference numerals. Under the envelope 6 and in parallel with the part 4 of the standard tube 5, a ventilation tube 80 is arranged, which allows an exchange of air between the area of ​​the ear canal between the eardrum and the part 4 of the standard tube 5 with the outside world.

For influencing voice modulation, feedback effects, ventilation, etc. has the ventilation tube 80 to a defined inner diameter. Alternatively, the ventilation tube 80 may be at the proximal end, that is, provided at the end which is accessible from the external ear of a plug 82 having a drilling 83 with a defined diameter, as can be seen in Fig. 14c. Since the plug is accessible from the outside 82, a plug 82 may be selected with a matching bore 83 on site. Furthermore, locking means not shown in detail 80 can be provided in the ventilation tube, with which the ventilation tube 80 may be closed more or less. Regarding this possibility is made to the G 90 03 269.1 in full respect.

Through the front panel and the battery compartment of a hearing aid can be covered. The cover of the Batterikammer can be embedded in the front panel, as can be seen from the figures 10b and 10c. The microphone opening may be positioned both below and on the front panel. The front panel also has a solar cell for energy supply of the hearing device may be located.

The elastic tubular or double smart shaped shell 6, 23, 42 or 62 is manufactured in different sizes and thicknesses, so that even in non-expanded state, a rough adjustment may be made to the respective dimensions of the ear canal.

The inventive hearing aids, it is also possible to locally select a matched to the respective characteristics of the wearer hearing aid. For this purpose a hearing aid is initially inserted with a doppelschlauchformigen shell and air is blown into the shell, so that the sleeve conforms closely to the ear canal and the concha. Then the acoustic characteristics are identified and selected one of each hearing ability fitted hearing aid. In-the-ear devices, the front panel is in this case adapted individually. Finally, the air from the doppelschlauchformigen sheath is removed and instead a fast curing plastics compound is introduced. By chewing movements of the wearer, the

Seat and fit the earpiece locally produced to be optimized.

Fig. 15 shows schematically an exemplary embodiment of the hearing test device according to the present invention.

The hearing test device shown in Fig. 15 consists of a central operating and control device 2, which is connected to a sound storage device 4, a display device 6, a speaker apparatus comprising two speakers 8 and 9 and with a test hearing device 10.

As can be seen from Fig. 16, the Testörgerät 10 includes a Stetho clip 12 to which a hearing aid module 11 is mounted. The hearing aid module 11 is a

Standard hose connected 14 with a standard shell 16 which is inserted into the ear canal of the patient. The Standardεchale 16 18 surrounded by a doppelschlauchformigen elastic sleeve of non-irritating material. By using different standard hoses or by the insertion of sound tubes defined diameter between standard shell 14 and hearing aid module 11 frequency problems or problems with the voice pitch of the user by appropriately trained personnel can be eliminated. These sound tubes are also used for ventilation of the ear canal. Also regarding the function and the structure of this Schall¬ or ventilation tubes, reference is made to the above embodiments.

With the hearing aid module 11 is different amplifier circuits such as AgCl, AGCO, PC, Kamp circuits can be displayed or realize etc.. The electronic system that realizes these various types of amplifiers may be either housed in the hearing aid module 11 itself or externally, for example in the control and operation means.

The patient or user of the hearing test arrangement according to the invention receives the Stetho clip with hearing aid module 11. The standard shell 14 of the hearing aid 10 with the sleeve 16 are inserted into the ear canal and via a valve (not shown) in the envelope 18 is air into the sheath 18 blown, so that the envelope 18 conforms closely to the auditory canal of the patient. In this way, the ear canal is sealed and feedbacks are avoided.

Subsequently, the user can automatically operate, and easy nungs- at the control means 2 different

Setting operating parameters of the test hearing aids, ie it can also change for example the gain in 5 to 10 dB jump in the range of 15 to 60 dB and can the frequency response in the range of 100 Hz to 6000 Hz (for broader band listeners in Nonslip classification 20-20000 Hz ) vary, in which case both broadband transmission and selective transmission of different narrower frequency ranges is possible.

For the actual test of the hearing aid, the patient can retrieve from the various Klangspeiehereinrichtung 4 him known noise or sound events whose significance or pictorial representation on the display device 6 illustrated and is emitted at the same time acoustically by the speakers. 8 and 9 Due to the optical display or presentation of the respective sounding sound product in the display device 6, the patient knows exactly which sound event just sounds or sounds and thus he knows how such a sound event, such. B. should sound the rustling of leaves in the wind. Therefore, it can change the various operating parameters of the Testörgeräts until he finds an optimal after his subjective feelings and natural sound impression.

carried out the testing of the speech understanding by retrieving a sound event that represents a spoken text. This is possibly. Make sense not to display the meaning of the text visually, since it is less about the naturalness of the sound and more about understanding as such in the understanding of speech.

In this self-test of the patient, it is of course vor¬ geous if the patient is not completely free in the choice of different parameters. Rather, it is also possible with the inventive hearing test arrangement to perform certain preselected test pattern and to go through. D. h. arises in the course of which the patient can choose different alternatives a "dialogue" between hearing test and patient. On the basis of the selected alternative will be decided by the test program, such as the test program is continued and is to be with which amplifier circuits or with which types of hearing aids further tested. In such a program-controlled self-test, the patient is primarily the degree of amplification, that the volume can be determined freely, while the other operating parameters of the hearing aid can be selected under program control. Of course, it also makes sense that trained staff is always available for questions of the patient.

Finally, the patient has found optimal for its needs hearing aid, this can be adapted to the individual auditory canal of the patient on the spot, in the doppelschlauchformigen from the sheath 18 let out the air and, instead, a fast curing plastics compound is introduced. the fit of the hearing or the default shell is optimized in the ear canal by chewing movements of the patient. Subsequently, the individually adapted hearing aid of the patient, so that a hearing aid with no connection to the actual hearing test arrangement, be tested again by calling up different sound events.

For the speaker devices preferably two or more spaced-apart speakers are used to test even the directional hearing of the patient or to this being able to select an optimal hearing aid. Of course, it iεt also possible that the different sound events can be generated by means of headphones. For sound storage devices both analogue sound storage may as tape etc. can be used as well as digital storage such as CD or, for example PCMCIA memory cards. The control and operating device can be a standard PC with appropriately equipped peripherals in particular. The peripheral devices here would include, in particular a so-called sound card, can be converted into corresponding analog electrical signals with the digitally stored sound events, which then sounded as a sound in the loudspeaker device. The use of a PC as a control and operating device also has the advantage that, that different test programs can be worn easily by software. For such test programs, it is also possible to use adaptive neural networks that adapt automatically to the respective patient.
