Definitions

  • the invention relates to a measuring system for standards measurement of hearing aids, comprising a measuring box with a measuring chamber for receiving a hearing aid and with connection means for electrical connections.
  • the adaptation of a hearing aid to the individual hearing loss of a user usually takes place in a hearing aid acoustician specially trained for this activity. This is equipped to perform its task with special diagnostic and fitting tools.
  • the well-known measurement and fitting system "UNITY 2" from Siemens Audi Vietnamese GmbH includes, for example, an audiometer module for measuring the individual hearing loss of a hearing aid wearer.
  • the known Messund fitting system comprises a probe-microphone module with which, for example, the frequency response of a hearing aid can be measured when it is worn on the ear of a user.
  • the known measuring and adjustment system comprises a measuring box unit, with which standard measurements on a hearing aid are possible, for example for performing measurements in accordance with the standards IEC 118-7 or ANSI 3.22.
  • the measuring box With a measuring box, the measurement of the input and output characteristics of a hearing aid can be performed.
  • the measuring box comprises a measuring chamber into which the hearing aid to be measured can be placed.
  • the measuring chamber is usually surrounded by sound-absorbing material.
  • a special hearing aid measurement that can be carried out using the measuring box concerns the telecoil.
  • an electromagnetic signal is generated by a transmitting coil and received by the telecoil of the hearing aid.
  • the signal thus received goes through the signal processing in the hearing aid and is finally delivered as an acoustic signal.
  • a coupler connected to the hearing aid is used, which simulates the auditory canal of a hearing aid wearer and converts the acoustic signal into an electrical signal, which is finally fed to an evaluation unit.
  • a transmitting coil is integrated into the known measuring box.
  • this is not suitable for carrying out all standard measurements in a hearing aid.
  • the measuring box of the well-known measuring and fitting system UNITY 2 with the integrated transmitting coil it is not possible to measure according to ANSI standard 3.22 (SPLITS measurement).
  • connecting means for connecting an external transmitting coil are present in the measuring box.
  • an external coil is z. B. the "Telewand" the company Frye known.
  • the transmitter coil is integrated in a hand-held housing. The telewall and the hearing aid to be measured are held together during the measurement so that the best possible inductive signal transmission can take place.
  • a disadvantage of measurements in connection with the wall is the cumbersome handling, in which the wall and the hearing aid with which the measurement is to be performed, must be held in the hand at the same time.
  • Object of the present invention is therefore to simplify the implementation of standard measurements in hearing aids using a measuring box.
  • the invention has the advantage that a telephone magnetic field simulator is used to perform measurements in connection with the telecoil of a hearing aid, having a storage device, for example, a flat plate, on which the hearing aid in question can be stored.
  • a coupler connected to the hearing aid during the measurement can likewise be deposited on the storage device of the carrier module.
  • the carrier module advantageously has electrical connections, so that an electrical connection of the coupler or the transmitting coil to the measuring box can be produced in a simple manner.
  • the hearing device can be positioned on the depositing device in such a way that the best possible signal transmission between the transmitting coil and the telecoil in the hearing device is achieved. Neither the hearing aid nor the transmitter coil must be held in hand to carry out the measurement. This facilitates the operation of the signal generators and measuring instruments used to carry out the measurement.
  • measuring box carrier module extends the functionality of the measuring box. Since only limited space is available in the measuring box for attaching different transmitting coils, usually only a telephone magnetic field transmission can be measured according to a specific standard. By using carrier modules with different transmitter coils, this measurement can in principle be extended to any number of different telephone magnetic field simulations.
  • the invention further has the advantage that more accurate measurement results are achieved by the easier handling over the telephone wall of Frye.
  • FIG. 1 shows a plan view of a measuring box 1 for carrying out standard measurements in a hearing device, which can be put into a measuring chamber 2 for this purpose.
  • the measuring box 1 has electrical connections 3A, 3B and 3C to which various devices required for carrying out measurements can be connected, for example a coupler connected to a hearing device or an external transmitting coil.
  • the measuring box 1 is connected via a data cable 4 to an external processor unit, for example a PC, via which the measuring box 1 can be supplied with test signals and measuring signals can be read out.
  • an external processor unit for example a PC
  • the measuring chamber 2 is surrounded by sound-absorbing material.
  • the upper side of the measuring chamber 2 can be closed by means of a cover 5 which is articulated to the measuring box 1 via a hinge 6.
  • hearing aids In addition to a microphone for recording acoustic signals, hearing aids often also have a telecoil for receiving inductive signals.
  • a transmitting coil 7 is present in the measuring box 1, which is located on the underside of the measuring chamber 2.
  • the invention therefore provides for a support module 10, the upper side of which is formed substantially as a flat plate 10A.
  • the carrier module 10 is also equipped with electrical connections 11A and 11B, which can be connected to the electrical connections 3A to 3C of the measuring box 1, for example by connecting cables (not shown).
  • a transmitting coil 12 which can be supplied via one of the electrical connections, such as the terminal 11A, a test signal, which can then be dispensed as an electromagnetic test signal and transmitted to a hearing aid to be measured.
  • To measure the hearing aid in question is placed on top of the carrier module 10. It is connected to read a inductively transmitted test signal to a coupler which provides an electrical signal to port 11B. This signal is then supplied to the external processor unit (not shown) for further evaluation via the measuring box 1 and the data cable 4.
  • the use of the carrier module 10 makes it much easier to carry out the measurement.
  • the hearing aid to be measured can be deposited and positioned on the carrier module 10 such that the best possible inductive signal transmission between the transmitting coil 12 and the hearing aid is achieved.
  • the replacement of existing in the measuring box 1 transmission coil 7 is thereby avoided as well as the handling of a hand-held external transmitter coil. It can thus be carried out in a simple manner measurements with different transmitting coils.
  • the carrier module 10 is designed so that it is used as a further lid of the measuring box 1 when the lid 5 is open can. So that it does not slip on the measuring box 1, the carrier module 10 has a circumferential edge 13, which engages in the measuring chamber 2. However, the carrier module 10 does not necessarily have to be mechanically connected to the measuring box 1 in order to carry out a measurement in connection with the transmitting coil 12. Likewise, the measuring box 1 and the carrier module 10 can be placed side by side. For this purpose, there are four feet 14A to 14D at the bottom of the carrier module 10th
  • FIG. 2 shows the carrier module 10 in a side view.
  • the flat top plate 10A can be seen, which serves to store a hearing aid and a coupler.
  • the two front feet 14A and 14B can be seen, on which the carrier module 10 can be placed.
  • the transmitting coil 12 is arranged on the underside of the flat plate.
  • the sockets 11A and 11B are provided at the top of the flat plate 10A.
  • the connector 11B for the coupler comprises an extension piece 15, the end of which is opposite the socket 11B designed as a plug to which a connection cable can be connected.
  • the feet 14A to D, the transmitting coil 12 and the extension 15 for the electrical coupler connection are screwed to the tray 10A, so that they can be removed or replaced if necessary.
  • different transmission coils or electrical connections can be used in a simple manner.
