Definitions

  • Hearing system usable for hearing-impaired persons is a hearing system for bringing sound coming from the environment to a person's ear, in particular a horse system for hearing-impaired people, having the following dimensions:
  • a central processing unit (4) which has an amplifier (30) and a current source for supplying the amplifier (30);
  • a hearing aid of this type has a microphone for picking up the outer scarf, an amplifier fed by a disposable battery and a scarf. Since such hearing aids have to be made very small due to the nature of the system, the core components named microphone, amplifier, battery, and pulse generator must be made extremely small. The sound quality of the sound waves emitted by the sensor is unsatisfactory. This is unfortunate because the hearing impaired would receive the most effective hearing aid by receiving sound in high 7 o ⁇ quality.
  • the invention solves the technical problem of providing a hearing system which can be used for hearing-impaired people and which is designed for sound delivery in very good sound quality and therefore provides very effective hearing aid.
  • the system according to the invention has a central unit which is separate from the microphone and the ear sound generator.

  • the components of the hearing system responsible for this are preferably designed such that the signal processing from the microphone input to the ear sound generator output takes place with a quality which is essentially at least at the level of today's good music reproduction from a music preserve.
  • a typical example of today's good music reproduction from a canned music is a CD player with loudspeaker or good headphones.
  • a modern DVD player with loudspeaker or good headphones delivers very good music reproduction from a music preserve today.

  • a quantization of at least 16 bits, preferably at least 24 bits, is preferably used.
  • the central unit of the hearing system according to the invention is - on an absolute scale - a very small and light unit. Typical dimensions are around the volume of a German matchbox, but flatter. In general, relatively flat designs are preferred due to the fact that they can be accommodated.
  • the central unit is carried separately by the user of the hearing system from the microphone and the ear sounder, particularly typical is carrying it in a jacket pocket or carrying it on the neck by means of a band or chain, as is known, for example, from carrying glasses that are not used all the time. It goes without saying that the central unit and its "neck hanger" are designed as elegantly and chic as possible, so that they are perceived more as jewelry than as a technical ballast.
