Definitions
- the present invention relates to a hearing aid according to the Preamble of claim 1.
- Hearing aids are used for one patient compensate for hearing loss compensate by being recorded with a microphone processed acoustic signals and amplified accordingly or changed into the ear canal of the Patient. Accordingly, there is one on the hearing aid Sound outlet provided through which the through acoustic signals generated in the ear canal be directed.
- a hearing device is known from EP-0 377 074-A2, the one Has handset with two openings, a first tubular channel from one opening of the receiver into the The patient's ear canal leads and a second tubular one Channel from the second opening of the handset to the outside facing side of the hearing aid - the so-called face Plate - leads.
- the inside of the handset shows one of the two Chamber connecting openings, which on one side is limited by a movable membrane, the Membrane through an actuator for generating acoustic signals can be deflected.
- the mentioned Chamber are two more chambers and openings in the Hearing aid housing provided, through which a Changes in height generated pressure difference between Ear canal and atmosphere with the hearing aid inserted can be compensated.
- Such Pressure compensation devices are also called "Pressure Vent "devices.
- deposits can now at most in the listener or in the channel to the ear canal of the Hearing aid wearer have fixed over time the listener and thus be removed from the hearing aid by the opening in the "Face Plate "is opened and with a syringe or the like. Detergent through the second channel, the handset and finally the first channel is pressed. With that any deposits that have been washed out. After this The cleaning process is the opening in the "Face Plate” in turn closed, so that - according to the known publication - no impermissible transfer function changes received become.
- the present invention is based on the object Specify hearing aid that one over the known Hearing aids have a much simpler structure, However, in no way does the known hearing aids function inferior.
- the invention has the following advantages: Hearing aid a handset with two openings is used by which have an opening through a canal with the ear canal of the hearing aid wearer and the other opening via one another channel connected to the outside world can do that Hearing aid in the simplest way, for example by Blow out, be cleaned.
- the channels also serve also as a pressure compensation device, i.e. as a so-called "Pressure vent” without causing an impermissible Change in the characteristic transfer function he follows.
- the hearing aid according to the invention has the advantage of that by choosing the right one Dimensions of the further channel, the Transmission characteristics of the first channel in the sense of a Line matching, where there are particular reflections too avoid, can be improved.
- the hearing aid 1 shows a hearing aid 1 according to the invention shown, consisting of a microphone, one Signal processing unit 4, an energy storage unit 3 and a receiver 5 which has two openings 8 and 9.
- the hearing aid 1 shown is a so-called ITE (in-the-ear) hearing aid, i.e. the hearing aid is in the outer auditory canal of the hearing aid wearer fitted.
- ITE in-the-ear
- BTE behind-the-ear
- the microphone 2 acoustic signals of the environment in electrical signals converted by the signal processing unit 4 be charged. Because of the already predetermined Hearing impairment of the hearing aid wearer's hearing is in the signal processing unit 4 a corresponding Signal processing, i.e. Reinforcement.
- the electrical output signal of the signal processing unit 4 is then applied to the listener 5, in which the electrical signals converted into acoustic signals be, which finally through an opening 8, a tubular channel 6 and a first output 12 in the Ear canal of the hearing aid wearer are guided.
- the receiver 5 has a second opening 9 on that via a tubular channel 7 and a second output 11 is connected to the outside world.
- the continuous connection between the auditory canal and the outside world, including the listener 4, allows blowing in the simplest way, i.e. Clean the components carrying the acoustic signals make.
- Hearing aid components i.e. Handset 5 and channels 6 and 7 provided air or detergent, for example with Help a syringe through these hearing aid components too press, all the more, in these existing Blow out impurities, i.e. to remove from these.
- the further channel 7 is also used used for any reflections due to of unmatched lines - i.e. due to channel 7 and other factors influencing the transfer (such as for example, the shape of the ear canal) - to be obtained compensate.
- Such "unadjusted lines” lead namely consistently to resonances in the listener 5, namely in Range of the break point in the frequency response of the listener striding higher frequencies. With that, too undamped and thus simpler in construction to listeners Use in the hearing aid according to the invention.
- the acoustic signals do not occur with BTE hearing aids at exit 12 into the ear canal, but it's a another element, often referred to as a hook element, required that the acoustic signals finally in guides the hearing aid wearer's ear canal.
- 1 is such a hook element indicated and with the Reference number 10 referenced. Because of compared to ITE hearing aids changed transmission properties is the second channel 7 accordingly, i.e. in the sense of im Made in connection with the line adjustment Explanations to adjust.
- Fig. 2 three frequency responses of the hearing aid 1 are in Range of low frequencies is shown in simplified form, whereby the corresponding hearing aids differ in that that their tubular channels 7 different Have diameter. So is the solid line Frequency response of a hearing aid 1 shown, in which a Channel 7 with a 2mm diameter is inserted. In contrast, a frequency response is shown in dashed lines, in which a Channel 7 with a 0.5mm diameter is used. Between lying, a variant is shown in which a Diameter between 0.5 and 2mm selected for channel 7 is. Although the selected diameter for channel 7 the preferred range is the choice in no way restricted by this information. Rather, restrictions result from the physical conditions, such as through a impending feedback from generated by the receiver 5 acoustic signals back into the microphone 2.
- the hearing aids according to the invention have the mentioned Advantages even if channels 6 and 7 are not are tubular. Rather, any means are conceivable to be provided in such a way that - in the case of channel 6 - in Handset 5 generates acoustic signals from one opening 8 of the receiver 5 in the auditory canal of the hearing device wearer reproduce and that - in the case of channel 7 - one Connection from the second opening 9 of the receiver 5 to Outside world is created. According to the invention another connection between the ear canal and the outside world dispenses with what a compared to the known hearing aids simpler construction is possible.
