- the frequency range is in particular from 100 Hz to 6 kHz is interesting for improving hearing.
- With directional microphone systems of the first order one obtains over this frequency range towards higher frequencies slightly falling directivity index.
- DI values For lower frequencies, for example up to 1 kHz, DI values of about 5 dB.
- Directional microphone systems of the nth order with n> 1 because of the high sensitivity to component tolerances a negative directivity index at low frequencies. But for that there are DI values for frequencies from 1 kHz to 5 kHz achievable of 7 dB and more.
- To also for low frequencies Being able to achieve higher DI values are close component tolerances (e.g.
- phase difference of the microphones involved ⁇ 0.25 °) must be observed, at best with silicon microphone arrays can be achieved. But these have the supply voltage used for hearing aids ( ⁇ 1V) Too high signal-to-noise ratio, resulting in use of these arrays is currently not useful.
- the invention has for its object a hearing aid and to offer a method for operating a hearing aid, where a high directivity index over a large one Frequency range of the input signal is reached.
- the hearing aid according to the invention comprises at least two Microphones to zero, first or higher directional microphone systems To be able to realize order.
- a directional microphone system Zero-order in the sense of the invention is a microphone system without understanding directivity, for example a omnidirectional not connected to other microphones Microphone.
- DI directivity index
- KEMAR a standard research manikin
- Directional microphone systems second and higher order have DI values of 10 dB and more on that, for example, for better speech intelligibility are advantageous.
- directional microphone systems can be zeroed out up to second order. Of these directional microphone systems can thus be microphone signals at the same time with zero to second order polar patterns.
- those of microphone systems are advantageous microphone signals in different order Weighted differently depending on the frequency summed.
- the weighting is preferably done through filter elements, the microphone signal of First-order directional microphone system of low-pass filtering and the microphone signal of the second-order directional microphone system is subjected to high pass filtering.
- General will at low frequencies essentially the microphone signal of the directional microphone first order and at high frequencies that Microphone signal of the n-th order directional microphone system for Further processing forwarded, where n for the highest occurring order stands.
- In the middle frequency range are preferably essentially the microphone signals of the Directional microphone systems between the first and the highest occurring order processed.
- the cutoff frequencies are the filter elements downstream of the directional microphone systems adjustable.
- the limit frequencies in the audible frequency range for example up to 10 kHz
- the associated frequency-dependent selection of directional microphone systems of different orders directivity properties are achieved for the overall system, the conventional hearing aids, over the entire Considered frequency range, are clearly superior. For every The frequency of the input signal is therefore an optimized directivity reachable.
- Modern hearing aids allow the classification of the acoustic Input signal in channels. This will, among other things a different amplification of individual frequency ranges allows.
- the cutoff frequencies of the directional microphone systems downstream filter elements at channel cutoff frequencies of the hearing aid. In the simplest case it forms each directional microphone system has one channel. The filter elements then to simultaneously weight the microphone signals the channel division, with which additional filter elements for Channel division can be omitted.
- the Hearing aid device can set the cutoff frequencies the location of individual or multiple cutoff frequencies also appropriate to the situation determined and continuously checked and adjusted become. This results in an optimized adaptation to different usage / noise situations.
- the analysis of the surrounding situation is preferably done by means of a neural Network and / or a fuzzy logic controller.
- the setting of the cut-off frequencies as well as the entire directional characteristic of the microphone system of a hearing aid the invention can - also depending on the set Hearing program done differently. It can be for one certain frequency range at least essentially also Zero-order microphone signal (microphone signal without directional effect) to be processed further.
- the output signals of the microphones are in order an electronic circuit ES interconnected.
- the electronic circuit arrangement ES for the formation of Directional microphone systems can electronic components, such as delay elements, summation elements or inverters, include.
- the directional microphone signals thus formed at the output the electronic circuit ES are used as a directional microphone signal zero order RS0, directional microphone signal of first order RS1, ...., directional microphone signal nth order RSn.
- Several directional microphone signals of the same order can also be used be formed.
- at least two directional microphone signals differ in terms of their order.
- the directional microphone signals are fed to a filter bank FB.
- the filter bank FB has filter elements, for example High pass, low pass or band pass filters.
- the directional microphone signals are dependent on the FB filter bank their order and their signal frequency differ attenuated.
- the cutoff frequencies are preferred and filter coefficients of the individual filter elements adjustable.
- the output signals (AS0, AS1 ... ASn) of the filter bank FB are to form the overall directional microphone signal GRS fed to a summation element S.
- a hearing aid can be used both in digital as well as in analog circuit technology. There can also be other elements Components such as A / D converters, D / A converters, switches, amplifiers etc. (not shown here).
- the circuit will be set up to to a lower limit frequency fg1, for example 1 kHz, at least essentially the directional microphone signal first Order is forwarded.
- fg1 for example 1 kHz
- the directional microphone signal of first order increasingly directional microphone signals higher order mixed and possibly the Low-order directional microphone signals even attenuated.
- FIG. 2 shows a hearing aid device as an exemplary embodiment three microphones 1, 2 and 3. Is in a signal line 11 a signal of a first order system with the directional microphone characteristic "undelayed eight" before when the input signals the microphones 1, 2 after inverting in the inverter 4 can be added via the sum element 7.
- the signal line 13 is a signal with the directional microphone characteristic "delayed eight" of a directional microphone system first order when the signals from the microphones 2 and 3 after inverting the signal of the microphone 3 in the inverter 5 added in the sum element 8 and subsequently in the inverter 6 inverted and delayed in the delay element 10.
- the microphone pairs 1, 2 and 2, 3 thus form the one shown Connection of a directional microphone system first Order.
