Definitions

  • the present invention relates to a system for adaptation at least one hearing aid according to the preamble of claim 1.
  • Hearing aid technology is increasingly moving towards to process the audio signals digitally.
  • Using a digital Signal processor unit is the transmission of audio signals ultimately on an electrical / mechanical output coupler made of the hearing aid.
  • the transmission behavior of the hearing aid between acoustic / electrical input and electrical / mechanical output converter is on the signal processor unit created so that individual hearing deficiencies be largely remedied by the hearing aid.
  • the rough coordination is usually carried out on the basis of diagnostic Data, such as from audio programs.
  • diagnostic Data such as from audio programs.
  • a first Matching at least some of the transmission parameters made on the hearing aid or even selected the hearing aid type.
  • the fine-tuning is then carried out in situ. Basically, an individual to whom an or two hearing aids are to be adjusted with the hearing aids to be matched equipped and exposed to test audio signals. It will Individual stopped the audio impression towards the test signals report, accordingly the parameter fine-tuning made on the hearing aid.
  • the assessment of the individual orally to a specialist such as a hearing aid acoustician.
  • a specialist such as a hearing aid acoustician.
  • he gives on an input unit usually a computer keyboard, inputs to the adaptation computing unit on. This determines or calculates manipulated variables for electronic units on the hearing aid, which via the mentioned communication connection from the adaptation computing unit be transmitted to the hearing aid.
  • Digital hearing aids are increasingly being adapted psychoacoustic perceptual values, namely loudness.
  • EP-A-0 661 905 corresponds to the US application 08/720 748 by the same applicant as the present applicant Registration referred. It explains, for example, how the psychoacoustic perception loudness of an individual can be evaluated scaled and like a computing unit according to the stimulus response, for the specific critical Human hearing frequency bands, transmission parameters on the hearing aid. This procedure is mentioned in the Scripture described in detail and only in so far for the present Invention important than that, for example is explained how a matching computing unit, due to scaled Loudness information from the individual, parameters of the transmission behavior determined on the hearing aid.
  • the hearing aid 1 shows the configuration of a system known today shown for in-situ adjustment of one or - in the binaural Case - two hearing aids.
  • it comprises an adaptation computing unit 1 with a digital computing unit 3.
  • manipulated variables determined by the digital process unit 3 transmit and guide the hearing aid 7 worn by the individual I. there for fine-tuning of parameters relevant to transmission.
  • the individual I becomes acoustic Subjected to test signals T and reacts by scaling of the perceived stimulus using an evaluation unit 9.
  • the scaling result becomes an interface unit 11 transmitted to the adaptation computing unit 1. It calculates the computing unit 3 from these evaluation signals R and usually the fine tuning of the previous experience.
  • the present invention relates to the communication link between matching computing unit 1, hearing aid 7 and evaluation unit 9. It sets itself the goal, the plant, as it schematically 1 is shown to simplify considerably.
  • the system of the type mentioned above is distinguished according to the characterizing part of claim 1. Accordingly, the first one Interface unit for outputting signals to at least a hearing aid that can be connected to it and the second interface unit for recording individual audio stimulus reaction signals through one and the same interface unit realized.
  • the interface used according to the invention is a bidirectional one Interface, i.e. both signals from the Computing unit originated as well as signals to the computing unit be directed.
  • the interface unit provided according to the invention is designed as an I 2 C 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 I 2 C 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, which are also sold by the Philipps company, in particular if further developed for two-way communication, as described in detail in WO99 / 13699 by the same applicant as the present application.
  • an evaluation input unit intended for audio stimulus response signals preferably in the form a keypad or a voice input unit, the Evaluation input unit can be connected to the interface unit is.
  • Interface unit physically within the matching computing unit to be provided, each with a physical connection for the at least one hearing aid and a connection for the evaluation input unit, is in a preferred embodiment the interface unit provided according to the invention as Branch unit formed, at least with one connection to the matching computing unit, one to an evaluation input unit and one to the at least one hearing aid.
  • a single one Interface unit 13 provided with the computing unit 3 communicates bidirectionally in the adaptation computing unit 1 and by means of which either the evaluation input unit 9 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. At a first connection 15 3 it communicates with the computing unit 3, at a second 15 9 with the evaluation input unit 9 and via a third 15 7 with the hearing aid 7. In a further preferred embodiment the communication between interface unit 13 and evaluation unit takes place. Input unit 9 and between interface unit 13 and hearing aids, K 15/9 or K 15/7 according to FIG. 2, via I 2 C bus connections, which is interface unit 13, at least what is the communication with said units 7 and 9 concerned, designed as an I 2 C interface. Corresponding I 2 C interfaces are provided on the units 9 and 7.
