Definitions

  • the present invention relates to a hearing device, in particular a hearing aid, with a microphone device which generates a specific wind noise signal in a wind, and a loudspeaker device. Moreover, the present invention relates to a corresponding method for operating a hearing device.
  • the microphones used on hearing aids for subsequent signal processing are usually positioned at an exposed point in order to ensure optimal sound pickup. Due to this placement, the microphones are prone to wind noise, which are perceived by the hearing aid wearer due to a disturbing, low-frequency rumble and drastically complicate communication in this acoustic situation.
  • An alternative way to reduce the low-frequency, wind-generated, rumble is to digitally suppress the wind noise after being picked up by the microphone or microphones. This is the switch from the multi-microphone operation to the omnibus operation and a significant reduction in the hearing aid gain in the lower channels is common. As with this actuator usually with Working very short time constants and large rule depths, clear artifacts are audible not only for normal hearing. Rather, the sound quality and speech intelligibility suffer greatly, while the wind noise usually remain audible with a reduced level.
  • a corresponding method is for example from the document DE 100 45 197 C1 known.
  • the method comprises an analysis of the output signals of at least two microphones of a hearing aid or a hearing aid system for the detection of wind noise. If there are wind noises, a signal processing unit of the hearing aid or of the hearing aid system and / or the signal paths of the microphones are adapted accordingly for their reduction. This can be done, for example, by switching from directional to omnidirectional operation, by filtering, adjusting the regulation times, switching off the microphones or reducing or closing the sound inlets.
  • the publication DE 299 16 891 U1 describes a tinnitus masking and hearing aid device which is portable in the concha of the pinna.
  • inner ear noises are covered by the signal of a noise generator.
  • the object of the present invention is to increase the hearing comfort of a hearing device, especially in windy conditions.
  • this object is achieved by a hearing device with a microphone device which generates a specific wind noise signal in a wind, and a loudspeaker device and an analysis device for analyzing a microphone signal according to the presence or the strength of the wind noise signal and a noise generator for generating a noise signal for presentation the speaker device in dependence on the Wind noise signal, so that the wind noise signal is at least partially hidden.
  • the invention provides a method for operating a hearing device, in particular a hearing aid, by recording a microphone signal, analyzing the microphone signal for the presence or the strength of a predefined wind noise signal and presenting a noise signal in response to the wind noise signal, so that the wind noise signal at least partially obscured becomes.
  • the idea of the invention is to produce the known wind noise artificially for the hearing aid wearer to him on the one hand to convey a natural hearing, and on the other hand to exploit the characteristic of this soft noise signal to mask occurring artifacts.
  • an artificial signal is thus generated to the optionally already pre-filtered useful signal and exploited its psychoacoustic perception to mask artifacts and remnants of the signal-related wind noise.
  • the noise generator is realized by a digital tone generator.
  • a digital tone generator As a result, any noise signals that come very close to natural wind noise can be generated.
  • the noise generator can also be formed by a microphone already present in the hearing aid or an existing A / D converter. This reduces the number of components installed in the hearing aid.
  • the hearing device according to the invention via a damping device for damping the specific Wind noise signal has, so that the noise generator generates the noise signal in response to the muted wind noise signal.
  • the wind noise is first reduced as much as possible in terms of data technology in order then to mask it with noise.
  • This damping device may for example have an adaptive filter.
  • the microphone device may comprise a plurality of microphones, which are switchable in response to the wind noise signal from a directional operation in an omnidirectional operation or vice versa. In this way, the number of wind noise sources can be reduced on the input side.
  • lower channels for lower frequencies can be automatically damped or reduced in the presence of a wind noise signal.
  • the wind noise less disturbing effect and the masking of the remaining wind noise can be achieved by a noise lower level.
  • a microphone M of a hearing aid shown schematically in the FIG is exposed to a wind, so that turbulence on the Mirkofonmembran lead to a so-called "rumble" R.
  • This rumble R is characterized by the fact that it has high levels in the low-frequency range.
  • the output signal of the microphone M is fed to a processing unit VE capable of causing the rumble R, d. h., The signal-related wind noise to dampen. This is achieved, for example, by reducing the gain in the low-frequency range.
  • the processing unit can also switch the microphone mode, for example, from the directional mode to the omnibus mode, so that the noise components decrease.
  • the signal-dampened wind noise at the output of the processing unit VE manifests itself as a bubbling B on the handset H of the hearing aid.
  • the level L of the bubbling B is below the level L of the rumble R, so that the bubbling B is less disturbing than the rumble R. Nevertheless, the bubbling B is a residual disturbance.
  • bubbling B is an unnatural noise
  • the noise N is generated by a noise generator RG.
  • a noise generator RG This means that in addition to the change of the microphone mode and the gain reduction in the low-frequency range, a technically generated, quiet noise signal is mixed to the existing useful signal to mask the audible artifacts and remnants of the wind noise caused by the algorithms.
  • the hearing aid wearer thus primarily perceives the artificially generated noise, since the bubbling B is obscured by the noise N.
  • the artificial noise N is perceived as less disturbing, as it corresponds to the natural perception of wind rather than bubbling B.
  • noise sources both digital sources such as tone generators on the hearing aid chip, as well as noise sources at the entrance of the hearing aid (microphones, A / D converter) are conceivable. Latter could be used as a noise source, for example, if the parameterization of the microphone noise suppression by an adaptive filter, eg. As a modified "WindNoiseCanceller", are changeable.
