Definitions

  • the present invention relates to a hearing aid test adapter for the soundproof connection of a hearing device output to a test microphone unit.
  • Hearing aids are portable hearing aids that are used to care for the hearing impaired.
  • different types of hearing aids such as behind-the-ear hearing aids (BTE) and in-the-ear hearing aids (ITO), e.g. also Concha hearing aids or canal hearing aids (CIC), provided.
  • BTE behind-the-ear hearing aids
  • ITO in-the-ear hearing aids
  • CIC canal hearing aids
  • the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
  • the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
  • the amplifier is usually integrated in a signal processing unit.
  • This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid.
  • a signal processing unit 3 which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them.
  • the output signal of the signal processing unit 3 is sent to a loudspeaker or
  • Handset 4 is transmitted, which emits an acoustic signal.
  • the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
  • the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
  • Hearing aids are to be tested before they are delivered or adjusted. For this purpose, they are usually placed in a test box. There they are connected with the help of an adapter with their sound output to a test microphone soundproof. A loudspeaker in the test box generates a test sound that a microphone of the hearing aid under test picks up. The recorded sound is further processed in the hearing aid and the amplified output sound is recorded by the test microphone.
  • the hearing aid output is connected soundproof to the test microphone.
  • a coupler which is filled with a reusable adhesive. This is sound-proof pressed against the shell of the IdOs, the CICs or the earmold of a BTE. This leaves only a sound tube from the sound outlet of the hearing aid through the coupler to the test microphone.
  • a microphone coupling for a hearing aid test system for connecting a hearing device and a microphone.
  • the microphone coupling is made of a rigid, unyielding material, preferably aluminum.
  • a non-hardening sealing material is used, eg a silicone plastic.
  • the object of the present invention is therefore to reduce the workload when coupling a hearing aid to a test microphone.
  • a hearing aid test adapter for soundproof connection of a hearing aid output to a test microphone unit, comprising a funnel-shaped, expandable first section for soundproof enclosure of a portion of a hearing aid shell or earmold such that the sound output of the hearing aid shell or earmold reaches the tip of the first section and a tubular, expandable second portion for soundproof enclosing a portion of the test microphone unit, wherein the tip of the first portion immediately adjoins the second portion and both are interconnected by a sound passage.
  • the funnel-shaped, expandable first section of the hearing aid test adapter allows a soundproof enclosure, in particular of a part of a hearing aid shell, by simply being pressed into the funnel.
  • the second likewise expandable, tubular portion ensures the acoustic tightness against the test microphone or a corresponding coupler.
  • the second portion has a polygonal opening, that is, the interior of the tubular portion is approximately prismatic.
  • the hearing aid test adapter can be held against rotation on the test microphone or the coupler when the hearing aid or the earmold is pressed in rotation in the funnel-shaped, first section.
  • a further preferred embodiment is that the first section is integrally connected to the second section. This reduces the manufacturing cost of the adapter and also ensures soundproofness between the two sections.
  • the first portion and the second portion each made of rubber or a rubber-like plastic.
  • the high elasticity of these materials ensures the necessary tightness.
  • a hearing aid test adapter set can be provided which, in addition to the hearing aid test adapter, also has an elastic plug for closing a vent in the hearing aid shell or the earmold on the sound output side.
  • This plug can be made of the same elastic material as the hearing aid test adapter. It is necessary so that the vent of the hearing aid to be tested or the earmold to be tested is closed, so that no direct sound can pass from the test loudspeaker to the test microphone through the vent.
  • a CIC hearing aid 11 is subjected to a sound test.
  • a Testboxlaut Maschinener 12 which generates a test sound 13. So that the acoustic conditions for the test are fulfilled, the hearing aid 11 to be tested must be located on a so-called test spot 14.
  • the hearing aid 11 is held with a rubber adapter 15 according to the invention soundproof on a coupler 16.
  • the coupler 16 in turn is on a test microphone 17th
  • the hearing aid test adapter 15 here consists of a molded rubber part, which in the enlarged view of FIG. 3 is better to recognize. It is substantially tubular and has a sidecut which divides it into a first section 151 and a second section 152. In FIG. 3 the two sections 151 and 152, which are integrally connected to each other, shown in longitudinal section.
  • the first section 151 is funnel-shaped and serves to receive the hearing device 11, here a CIC hearing aid. With its tip, the funnel-shaped first section 151 opens into the second section 152 via a sound opening 153.
  • This second section can be cylindrical, or as in the example of FIG FIG. 3 prism-shaped. Specifically, the shape of a hexagonal prism is chosen here.
  • This form also has the coupler 16, which of the second section of the Hearing aid test adapter 15 is enclosed soundproof.
  • the sound-tightness is ensured, as in the first section 151, by the fact that the adapter material is stretchable and can therefore be mounted on the slightly larger hearing device 11 or the slightly larger coupler 16 and produces the respective frictional connection.
  • the second section 152 is prism-shaped as mentioned. Then, when the hearing aid 11 is inserted into the funnel-shaped first portion 151 by a spin-push motion, the adapter 15 does not rotate on the coupler 16, which may be necessary for alignment purposes, but also improves the overall fit of the adapter.
  • FIG. 3 also shows the test microphone 17 to which the coupler 16 is mounted soundproof or screwed.
  • FIG. 4 is the arrangement of FIG. 3 shown in the side view.
  • the CIC hearing aid 11 is removed here from the funnel-shaped first section 151 or not yet inserted in this section. Namely, before the hearing aid is plugged into the adapter 15, a vent 111 of the hearing device 11 is to be closed on the sound output side with a plug 18. Only in this way can it be ensured that the sound of the test loudspeaker 12 does not pass through the vent 111 to the test microphone 17.
  • This plug 18 is shown in the removed from the hearing aid 11 state. Depending on the diameter of the vents 111, this plug 18 has a different size. However, it also consists of an elastic material, such as rubber, so that it is easily inserted into the vent 111 and there automatically holds by friction.
  • a plurality of hearing aid test adapters 15 may be provided which have differently shaped first sections 151.
  • the depth or opening width of the funnel may be different. This makes it possible, different shaped hearing aids 11 in a suitable manner, ie also sufficiently deep, in the first section 151 to use. Exemplary is in FIG. 6 indicated that an ITE hearing aid 19 in the first section 151 of the adapter 15 can be used.
  • FIG. 7 shows the hearing aid test adapter 15 according to the invention in the middle in longitudinal section, above it in a plan view from the side of the first section and below in a bottom view from the side of the second section 152. It can be clearly seen that the second section 152 in the axial projection hexagonal is. In addition, it can be seen in the drawings that the first section is connected to the second section through a sound opening 153. It ensures that the sound generated by the hearing aid 11, 19 can pass into an opening of the coupler 16.
  • the arrows 20 and 21 indicate that the hearing aid test adapter 15 can be stretched both in the region of the first section 151 and in the region of the second section 152 in order to soundproof the body of the hearing aids 11, 19 or of the coupler 16 , As a result, the installation time of the hearing aid in the test box and thus the total test time can be significantly reduced. In addition, the test results are significantly improved by the elastic hearing aid test adapter, as a soundproof fit of the hearing aid on the coupler or on the test microphone can be better ensured.
