Definitions

  • the present invention relates to a hearing aid with a plurality of microphones, a noise detection device for detecting a wind-induced noise and for outputting a corresponding detection signal and a signal processing device for driving the plurality of microphones in response to the detection signal. Moreover, the present invention relates to a corresponding method for controlling a plurality of microphones of a hearing device.
  • Hearing aids which also allow direction-dependent hearing, in principle have a higher sensitivity to wind due to the forward drawn position of the microphones.
  • the low-frequency pseudo sound caused by turbulent currents on the head and on the auricle (pinna) or the edge of the auricle (helix) is particularly noticeable. This pseudo sound is audible only in the near field and occurs at the pinna and in the back of the head. Since the microphones are due to the function immediately adjacent to the pinna, this pseudo sound is amplified by the hearing aid and leads to an unpleasant noise ("rumble").
  • a similar hearing aid is for example from the document WO 03/059010 A1 known.
  • This hearing aid has two microphones that have different sensitivity to wind noise. The wind noise level of one of the Microphones are recorded and this signal is used to decide which of the two microphones should provide the input signal for further signal processing. However, it can not be ascertained whether the microphone with the generally lower wind sensitivity actually delivers a lower wind noise signal in the specific situation.
  • a hearing aid with adaptive adaptation of the input transducer known. For example, when wind is detected, not only the transducers but also, for example, the signal filtering are adjusted. Specifically, it is proposed to switch from the directional operation to the omnidirectional operation when wind noise is detected.
  • the windshielded microphone may be used as the input transducer.
  • the object of the present invention is therefore to further reduce the sensitivity of hearing aids to disturbing wind.
  • this object is achieved by a hearing device with a microphone device having a plurality of microphones, a noise detection device for detecting a noise caused by wind and for outputting a corresponding detection signal and a signal processing device for driving the microphone device in response to the detection signal, wherein each noise level by the noise detection device of at least two of the a plurality of microphones can be detected and in the signal processing device, the at least two noise levels comparable with each other and a corresponding drive signal to the microphone device can be output.
  • the invention provides a method for controlling a plurality of microphones of a hearing device by detecting a wind-induced noise and outputting a corresponding detection signal and driving the plurality of microphones in response to the detection signal, wherein a noise level of at least two of the plurality of microphones is detected, the at least two noise levels compared with each other and the microphones are driven according to the comparison result.
  • the invention is based on the idea of measuring the actual noise level caused by wind on a plurality of microphones of the hearing device and controlling the microphones as a function thereof.
  • the wind noise intensity is measured at several hearing device points and the hearing device is controlled accordingly.
  • the drive signal is a signal for driving the microphones in an omnidirectional operation.
  • an increase in the signal-to-noise ratio can be achieved.
  • the noise generated by the wind in particular, is constantly detectable with the noise-determining device and the microphones can be correspondingly continuously driven by the signal-processing device. As a result, the microphones can be controlled and switched depending on the situation.
  • the microphone with the lowest noise level can be recognized by the signal processing device, this microphone can be used for omnidirectional operation and / the other microphones can be switched off. As a result, only the microphone that is least affected by the wind can be used for the signal processing.
  • the signal processing device can have a classifier for selecting the microphone (s) for the further signal processing on the basis of the noise level. In this way, the microphones can be targeted switch to the appropriate operation.
  • Directional hearing aids have several microphones that functionally not at the same point of the hearing aid have their outlet. Therefore, when the hearing aid is worn, the outlet openings are also not placed at the wearer's ear at the same point of the head or pinna. Consequently, the individual microphones, as shown in Figure 1, a different wind sensitivity depending on the location of the ear and of course the shape of the pinna. In the present example, not only the wind is detected with the microphone array in the hearing aid (two to three microphones), but also measured at the same time by internal level meter frequency-specific wind noise. According to FIG.
  • a first noise spectrum R1 results for a first microphone, a second noise spectrum R2 for a second microphone and a third noise spectrum for a second microphone a third noise spectrum R3.
  • the level of the third noise spectrum R3 of the third microphone is below the noise levels of the other two microphones in all spectral ranges. A corresponding comparison would therefore lead to the result that the third microphone is least affected by the wind in the entire spectral range. Thus, in the current situation, it should be used as the sole omnidirectional microphone.
  • the noise spectrum R2 is higher than the noise spectrum R1 in the middle frequency range and lower than this in the higher frequency range. If a hearing aid were equipped only with these two microphones, then these two microphones could be switched in the current wind situation so that the second microphone in the low and medium frequency range and the first microphone in the higher frequency range serves as omnidirectional microphone. This means that the microphones for each wind situation are frequency-specifically controlled or switched.
  • the comparison of the level spectra can be carried out, for example, with the aid of adjustable threshold values.
  • the aid of a classifier With the aid of a classifier, the more suitable for the wind situation omni-directional microphone signal or a combination of microphone signals (eg, sum of two or three microphone signals) can be selected.
  • a further reduction of the wind noise induced by pseudo noise can be effected, depending on the wind speed / turbulence intensity and position of the microphones on the head.
  • the hearing aid has three microphones M1, M2 and M3.
  • the noise signals of all three microphones M1, M2 and M3 are measured in a level meter P.
  • a downstream comparator C compares the level spectra optionally with certain thresholds.
  • a subsequent classifier K decides, based on the comparisons, which microphone is to be used for signal processing in the hearing aid as an input signal converter. Controlled by the signal from the classifier K, a multiplexer M switches the corresponding signal for omnidirectional operation for further signal processing.
  • a wind detector W determines whether there is any wind noise at the microphones. Only when wind is detected, the multiplexer M is activated and it is the appropriate microphone, if necessary frequency-specific switched through. If, however, no wind is detected, the signals of all microphones are used to obtain a directivity. It may also be useful to switch a pure omni-directional signal, formed from signals from M1 or any combination of M1 and Mn, into a wind-reduced omnidirectional signal from another microphone M2 or M3.
