Definitions

  • the invention relates to a hearing aid that can be worn in the ear or Hearing aid with earmold that can be worn in the ear with a Ventilation duct.
  • the ventilation duct also as a ventilation hole or short Vent refers to a hearing aid worn in the ear or a hearing aid with earmold earmould the ventilation of the ear canal, the atmospheric pressure balance or to reduce the closure effect (occlusion effect). For this is the largest possible cross section of Ventilation ducts desirable.
  • US 6,339,648 B1 can be inserted into an ear canal Part known.
  • This part can be used as earmold with a hearing aid worn behind the ear, as a hearing protection device or as a hearing aid worn in the ear be.
  • a first channel the part can be filled so that the outer shape of the part is personalized adjusts the respective auditory canal.
  • a ventilation duct with consistent over its entire course Cross-sectional area available.
  • there is an acoustic channel present which is widened at one end and thereby in the execution of the part as a hearing protection device Plug and in the execution of the part as earmold one Sound tube can record.
  • U1 is an earmold with a ventilation duct known.
  • a blocking means used in one at the distal end of the earmold intended extension of the ventilation duct.
  • This is as a rotatably mounted, cylindrical Part formed with an eccentric opening, wherein the diameter of the opening is the diameter of the ventilation duct equivalent.
  • Object of the present invention is the ventilation duct in a hearing aid worn in the ear or a hearing aid so educate with earmold earmould that a good ventilation effect is achieved and at the same time the risk of feedback through the ventilation duct is minimized.
  • This task is for a hearing aid that can be worn in the ear or Hearing aid with earmold that can be worn in the ear with a Ventilation channel solved by the fact that the ventilation channel in subdivided at least a first and a second subarea is worn with the worn hearing aid or worn Otoplasty proximal first portion of a first cross-sectional area and a first length and the distal one second portion a smaller length and a larger cross-sectional area compared to the first subarea and wherein the distal end of the second portion the distal ventilation opening of the ventilation duct forms.
  • the ventilation duct in the first Approximation by a transmission of the sound pressure over a Mass be presented.
  • the outlet of the ventilation duct, the so-called ventilation opening emits a sound signal in the free space, which in turn via a moving medium mass can be described.
  • This massed division of the adjacent sound pressure is approximately frequency independent and ensures a strong radiation from the ventilation opening.
  • the cross sectional area of the second portion advantageously at least three times Has cross-sectional area of the first portion, which a substantial reduction of radiation from the ventilation opening radiated sound components is achieved.
  • An embodiment of the invention provides, in particular for longer ventilation channels acoustic filter elements are arranged in a ventilation duct. Longer ventilation channels cause the occurrence of conduction resonances, where the acoustic conductivity of the ventilation duct is maximized. By the acoustic filter elements is the Occurrence of resonance effects prevented.
  • the filter elements For example, as cross-sectional jumps or than in the Ventilation duct introduced acoustic damping elements be educated.
  • FIG 1 is a schematic, highly simplified representation a arranged in the ear canal 1 of a hearing aid wearer Hearing aid 2 shown.
  • An acoustic signal will be the ear of the hearing aid wearer on the one hand via a microphone 8, a signal processing unit (not shown) and a Handset 3 with associated handset channel 4 and on the other hand supplied to the ventilation duct 5.
  • the ventilation duct 5 provides thus a bypass to the electroacoustic signal path through the hearing aid 2. In certain acoustic situations, e.g. with low acoustic amplification of the hearing aid due to a loud sound environment, this bypass is dominant over the signal path through the hearing aid.
  • the Hearing aid can lead to certain functions of the Hearing aid, such as a desired directivity or a noise reduction, only limited execution can be.
  • it can through the ventilation duct 5 also to feedback between the handset 3 and the Microphone 8 come.
  • the recorded by the microphone 8 and converted into electrical signals acoustic input signals are passed through the signal processing unit and then fed to a handset 3.
  • This radiates again via the listener channel 4 acoustic signals in the ear canal. 1 from.
  • About the proximal ventilation opening 7 and the ventilation channel 5 get these acoustic signals partially back to the outer space and reach after the radiation from the distal ventilation opening 6, the microphone 8.
  • the Feedback path is closed. Therefore, the ventilation duct should 5 only a relatively small cross-sectional area exhibit. However, this worsens the ventilation of the completed by the hearing aid 2 part of the ear canal 1.
  • FIG. 2 likewise shows a hearing aid 2 that can be worn in the ear, which is located in the ear canal 1 of a hearing aid wearer.
  • the ventilation duct according to the invention modified so that a head facing away from the second Part 5B of the ventilation duct with respect to a first, the head facing portion 5A is widened, which the second sub-area 5B is opposite to the first sub-area 5A has enlarged cross-sectional area.
  • the length ratios the subregions are preferably so dimensioned that the portion 5A much longer than the Part 5B is. This ensures that the flow resistance the ventilation duct substantially the Flow resistance of the portion 5A corresponds.
