Definitions
- the present invention relates to a method for controlling the dynamic range according to the preamble of claim 1, a method for manufacturing hearing aid types with different transmission characteristics according to the preamble of claim 6, further a hearing aid with at least one acoustic / electrical input converter according to the preamble of claim 7 and an electromechanical transducer according to that of claim 12.
- Hearing aids usually comprise at least one acoustic / electrical input converter, followed by a signal processor unit, which acts on the output side on an electrical / mechanical converter.
- the signal processor unit is correspondingly designed as a digital unit with an analog / digital converter on the input side and, if necessary, a digital / analog converter on the output side. This applies both to in-ear devices and to outside-ear devices in which the electrical / mechanical converter on the output side is usually formed by a loudspeaker arrangement
- the control method mentioned at the outset is characterized in that the input impedance of the acoustic / mechanical converter is selectively switched.
- the invention is therefore based on the knowledge that the dynamic range installed on a hearing device of the type mentioned also largely depends on the input impedance of the electrical / mechanical converter. By simply switching this input impedance to different impedance values, the aforementioned dynamic range can therefore be selected very easily.
- the dynamic range can be changed according to the hearing damage to be remedied or, depending on the situation, depending on the perceived acoustic environment, or in the case of headphones, for example, according to the current needs.
- the method involves a selective connection of the input impedance in order to adapt the hearing device, in particular the hearing aid device, for example to the audiologist, in order to achieve a desired dynamic range.
- the switchover be carried out by the signal processor unit, i.e. adaptively adapted to the respective acoustic environment.
- the input impedance switchover according to the invention can be carried out automatically, as mentioned by the signal processor, and / or can be triggered externally by the hearing aid, be it by manual intervention on the hearing aid itself, in particular in the case of headphones or an external ear hearing aid, or by remote control , if necessary and preferably in combination with a remote control for the control of the signal processor unit.
- the proposed concept according to the invention now also provides the possibility of producing different types of hearing aids much more cost-effectively than if the type-specific dynamic range can be implemented in hardware and / or software on each of the individual device types.
- this is namely by achieving that the different hearing aid types are constructed in the same way and the type-specific dynamic range is set by selectively connecting the input impedance of the electrical / mechanical converter.
- This makes it possible to concentrate the production of different hearing aid types on those of a single basic hearing aid type and, after that, to select the dynamic range required in each case by means of the switchover according to the invention.
- a hearing aid according to the invention is characterized in addition by preferred embodiments according to claims 8 to 11.
- an electromechanical transducer for a hearing device is proposed, on which, when integrated therein, the precautions for implementing the method according to the invention are implemented.
- a hearing aid for example a headphone or - and in particular - an outer ear or in-the-ear hearing aid, but also possibly a cochlear implant, includes an acoustic / electrical converter 1 on the input side, which is connected downstream of a signal processor unit 3 , a digital processor unit for a digital hearing aid.
- An electrical / mechanical converter unit 5 according to the invention is provided on the output side of the signal processor unit 3.
- the converter unit 5 comprises the actual mechanical / electrical converter 5a, which has an input impedance Z e with respect to the input E 5 to the converter unit 5.
- the input impedance Z e of the converter 5a is now switchable to different impedances Z el l
- switchover unit 7 which can be controlled via a control input S for switchover.
- switching elements are provided which, via a control input S, allow the input impedance Z e of the electrical / mechanical converter on the output side to be switched to previously selected, given impedances.
- the control of the input impedance switchover can in principle be done manually - one - be it by local direct intervention - Loc - on a switching element, be it by a remote alarm control - Rem -, in particular via a possibly remote control provided for controlling the signal processor unit anyway.
- the respective selective activation of the input impedance Z e of the electrical / mechanical converter can, however, if necessary combined with the manual activation, also be triggered automatically by the signal processor unit 3 take place, as shown in Fig. 1. It is thus possible, in a practically adaptive manner, to automatically track the dynamic range of the hearing aid to the operating mode which is respectively applied to the processor unit and is thus practically dependent on the acoustic environment.
- the switchover unit 7 can also be designed as a separate switching unit installed between the output of the signal processor unit 3 and the input of the converter mentioned. Preferably, and as is also shown in FIG. 2, it is integrated in a modular electrical / mechanical converter 15.
- FIG. 2 schematically shows an electrical / mechanical converter 17, which is common in hearing aids, in the form of a loudspeaker with an inductive driver 19.
- the driver 19 comprises, for example, two coils 19a and 19b.
- these coils 19a, 19b are connected either in series or in parallel, as a result of which the input impedance of the module 15, which is at least co-determined by these coils, is switched.
- the first-time selective input impedance selection is made there by appropriate connection. This activation can be carried out until a change is made as required - again by a specialist, for example the audiologist - be maintained or, based on this basic adjustment, either automatically or manually by the individual during the use of the hearing device, the input impedance is switched.
- a specialist for example the audiologist - be maintained or, based on this basic adjustment, either automatically or manually by the individual during the use of the hearing device, the input impedance is switched.
- the possibility is then preferably given to switch back to the basic setting of the input impedance mentioned made by the specialist at any time.
- the procedure according to the invention makes it possible to switch the dynamic range of the hearing aid with extremely simple means, but it also makes it possible, with a view to the production of hearing aids, to manufacture different types of hearing aids, which essentially differ only in the dynamic range, and to produce the type assignment of the hearing aid to produce the devices produced only after the actual production by selectively selecting the input impedance mentioned and thus the dynamic range, possibly even only by the specialist who undertakes a professional adjustment, such as the audiologist mentioned.
