Definitions
- the invention relates to a hearing aid or wearable in the ear Hearing aid with earmold that can be worn in the ear with one Ventilation duct.
- the ventilation duct also as a ventilation hole or short Vent means a hearing aid or portable hearing aid a hearing aid with earmold that can be worn in the ear ventilation of the ear canal, atmospheric pressure equalization or to reduce the occlusion effect.
- the largest possible cross section of the Ventilation duct desirable.
- he provides one acoustic bypass to the signal path via the input converter, the signal processing unit and the output converter of the Hearing aid is what, especially in a loud sound situation can cause functions of the hearing aid like a special directivity or noise reduction become ineffective.
- US Pat. No. 6,339,648 B1 can be used in an ear canal Part known.
- This part can be used as an earmold with a hearing aid that can be worn behind the ear as a hearing protection device or designed as a hearing aid that can be worn in the ear his.
- the part can be filled through a first channel, so that the outer shape of the part is individual adapts the respective ear canal.
- there is an acoustic channel present that is widened at one end and thereby when executing the part as a hearing protection device Plug and when executing the part as an otoplastic one Can accommodate sound tube.
- the object of the present invention is the ventilation duct in the case of a hearing aid that can be worn in the ear or a hearing aid with earmold that can be worn in the ear 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 or portable hearing aid Hearing aid with earmold that can be worn in the ear with one Ventilation channel solved in that the ventilation channel in divided at least a first and a second partial area is, with the hearing aid worn or worn Otoplasty proximal first section a first cross-sectional area and has a first length and the distal second section a smaller length and a larger cross-sectional area compared to the first section.
- the ventilation duct can first Approximation by a transmission of the sound pressure over a Mass are shown.
- This mass distribution of the applied sound pressure is approximately independent of frequency and ensures a strong radiation from the ventilation opening.
- a modified cross-section acts at the end of the Ventilation duct with otherwise unchanged ventilation duct a reduced radiation impedance.
- the advantage over The conventional ventilation systems consist of reducing acoustic radiation in the room. This gives one significantly improved stability of the hearing aids in practice and also allows the use of a ventilation duct with compared to a conventional hearing aid or conventional earmold enlarged in all areas Cross-sectional area while maintaining the stability conditions.
- the hearing aid is worn or worn Otoplasty proximal part of the ventilation channel according to the invention much longer than the distal portion with the enlarged cross-sectional area. So it is achieved that the flow resistance of the ventilation duct in the Remains essentially unchanged.
- the length of the first section is at least that should be five times the length of the second section.
- the cross sectional area of the second partial area advantageously at least three times Cross-sectional area of the first partial area, with what a significant reduction in radiation from the ventilation opening radiated sound components is reached.
- An embodiment of the invention provides that in particular acoustic filter elements for longer ventilation ducts are arranged in a ventilation duct. Longer ventilation channels cause the occurrence of line resonances, where the acoustic conductivity of the ventilation duct is maximized.
- the acoustic filter elements will Prevents resonance effects from occurring.
- the filter elements can, for example, as cross-sectional jumps or as in the Ventilation channel inserted acoustic damping elements be trained.
- FIG 1 is a schematic, highly simplified representation one arranged in the auditory canal 1 of a hearing device wearer Hearing aid 2 shown.
- An acoustic signal will appear the ear of the hearing aid wearer on the one hand via a microphone 8, a signal processing unit (not shown) and one Handset 3 with assigned handset channel 4 and on the other hand the ventilation duct 5 supplied.
- the ventilation duct 5 provides thus bypasses the electroacoustic signal path represents the hearing aid 2.
- this is bypass dominating compared to the signal path through the hearing aid. This can lead to certain functions of the Hearing aids such as a desired directivity or noise reduction, only limited can be.
- the ventilation duct 5 can pass through the ventilation duct 5 also to feedback between the receiver 3 and the Microphone 8 come.
- the recorded by the microphone 8 and acoustic input signals converted into electrical signals are passed through the signal processing unit and then fed to a receiver 3.
- This in turn shines 4 acoustic signals into the ear canal 1 via the ear canal from.
- Via the proximal ventilation opening 7 and the ventilation channel 5 these acoustic signals arrive partially back into the outside space and reach after the radiation the microphone 8 from the distal ventilation opening 6
- the feedback path is closed. Therefore, the ventilation duct 5 only a relatively small cross-sectional area exhibit. However, this worsens ventilation of the part closed by the hearing aid 2 of the ear canal 1.
- FIG. 2 also 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 second turned away from the head Subarea 5B of the ventilation duct compared to a first, the portion 5A facing the head is expanded, with what the second section 5B is one compared to the first section 5A has increased cross-sectional area.
- the aspect ratios the subareas are preferably so dimensioned that the portion 5A much longer than that Subarea 5B is. This ensures that the flow resistance of the ventilation duct essentially that Flow resistance of section 5A corresponds.
