Definitions

  • the present invention relates to a system for adapting at least one hearing aid according to the preamble of claim 1.
  • Hearing aid technology is increasingly moving towards digitally processing audio signals.
  • the transmission of audio signals to an electrical / mechanical output coupler of the hearing aid is ultimately carried out by means of a digital signal processor unit.
  • the transmission behavior of the hearing aid between the acoustic / electrical input transducer and the electrical / mechanical output transducer is created on the signal processor unit in such a way that individual hearing impairments are largely eliminated by the hearing aid.
  • the coarse tuning is usually carried out on the basis of diagnostic data, such as from audio programs. On the basis of such data, a first adjustment of at least some of the transmission parameters is carried out on the hearing aid or even the hearing aid type is selected.
  • the fine-tuning is then carried out in situ.
  • an individual to whom one or two hearing aids are to be fitted is equipped with the hearing aids to be tuned and test audio signals are exposed. It will Individuals are encouraged to report the audio impression to the test signals, so the parameters are fine-tuned on the hearing aid.
  • the individual is verbally assessed to a specialist, such as a hearing care professional.
  • a specialist such as a hearing care professional.
  • he gives inputs to the adaptation unit on an input unit, usually a computer keyboard.
  • this determines or calculates manipulated variables for electronic units on the hearing aid, which are transmitted from the adaptation computing unit to the hearing aid via the aforementioned communication connection.
  • Digital hearing aids are increasingly being adapted according to psychoacoustic nutritional parameters, namely loudness.
  • EP-A-0 661 905 corresponding to US application 08/720 748 by the same applicant as the present application. It explains, for example, how the psychoacoustic perception size of loudness can be evaluated by an individual on a scaled basis and how a computing unit sets transmission parameters on the hearing aid in accordance with the stimulus response for the specific critical frequency bands of human hearing.
  • This procedure is described in detail in the mentioned document and is only of importance for the present invention in that it explains, for example, how an adaptive computing unit determines parameters of the transmission behavior on the hearing aid based on the individual's scaled loudness information.
  • X shows the configuration of a system known today for the in-situ adaptation of one or - in the binaural case - two hearing aids.
  • the manipulating computing unit 1 transmits the manipulated variables determined by the digital process unit 3 to the hearing aid 7 worn by the individual I, where they lead to fine-tuning parameters relevant to transmission.
  • the individual I is subjected to acoustic test signals T and reacts by scaling the perceived stimulus using an evaluation unit 9.
  • the scaling result is transmitted to an interface unit 11 on the adaptation computing unit 1.
  • the arithmetic unit 3 calculates the fine-tuning of the parameters from these evaluation signals R and usually from the experience of the previous experience.
  • the present invention relates to the communication link between the adapting computing unit 1, the hearing aid 7 and the evaluation unit 9. It has the goal of significantly simplifying the system, as is shown schematically in FIG. 1.
  • the system of the type mentioned above is characterized by the characterizing part of claim 1. Accordingly, the first interface unit for outputting signals to at least one hearing device that can be connected to it, and the second interface unit for receiving individual audio stimulus reaction signals, are implemented by one and the same interface unit.
  • the highest safety requirements are imposed on electromedical interfaces via which electrical signals are transmitted in situ to devices, which leads to complex interfaces, for example with galvanic signal separation.
  • the evaluation unit 9 should also be viewed critically, although less critically than at the ear, so that by combining the two interfaces according to the invention, the well-known advantage is achieved that with one and the same interface, both are designed to be relatively complex for the electro-medical safety requirements Devices, namely hearing aid and evaluation input unit, are optimally filtered.
  • the interface used according to the invention is a bidirectional interface, that is to say that signals originating from the computing unit must be output as well as signals must be routed to the computing unit.
  • the interface unit provided according to the invention is designed as an IC interface unit and the communication connections on the one hand to the at least one hearing aid, and on the other hand to the evaluation input unit as a two-line IC bus.
  • This two-wire control bus technology is widely known and is currently marketed by the Philipps company.
  • the communication link can also be established, for example, via I 2 S interfaces, also sold by the Philipps company, in particular if further developed for two-way communication, as is described in detail in WO99 / 13699 by the same applicant as the present application.
  • an evaluation input unit for audio stimulus reaction signals preferably in the form of a keypad or a voice input unit, is provided on the system, in a ready-to-use constellation, the evaluation input unit being connectable to the interface unit.
  • the interface unit provided according to the invention designed as a branching unit, at least with one connection to the adaptation computing unit, one to an evaluation input unit and one to the at least one hearing aid.
  • the communication between the provided interface unit and hearing aid or evaluation input unit takes place in a wired or wireless manner, for which purpose, on the hearing device side, a receiver stage, on the part of the evaluation input unit at least one transmitter and, accordingly, transmitter and receiver must be provided on the interface unit.
  • FIG. 1 shows a system according to the invention.
  • a single interface unit 13 is provided for communication both with the evaluation input unit 9 and with the hearing aid 7, which communicates in two directions with the computing unit 3 in the adapting computing unit 1 and by means of which either the evaluation input unit 9 is released for writing data to the computing unit 3 or the computing unit 3 for outputting data to the hearing aid 7.
  • the interface unit 13 provided in accordance with the invention can in principle be placed anywhere near the computing unit 3, but - as the preferred embodiment according to FIG. 2 shows - is designed as a branching unit 15.
  • communication takes place between the interface unit 13 and the evaluation input unit 9 and between the interface unit 13 and hearing aids, K 15/9 or K ls / 7 according to FIG. 2,
  • the interface unit 13 is at least as an I 2 C interface, as far as the communication with said units 7 and 9 is concerned.
  • Corresponding I 2 C interfaces are provided on the units 9 and 7.
  • all of the communication connections K mentioned, including those between the interface unit 13 and the computing unit 3, can be implemented wirelessly, individually or in combination, for which purpose corresponding transmitter / receiver devices (not shown) on the units 1, 15, 9 and 7 are to be provided.
  • the interface unit 13 is controlled by the computing unit 3 in order to establish the sequential communication between the evaluation input unit 9 and the computing unit 3 or the computing unit 3 and the hearing aid 7.
