Definitions
- the present invention relates to a hearing aid with a Estimation device for estimating a useful signal from a disturbed input signal and a signal processing device for processing the payload signal to a payload output signal. Moreover, the present invention relates a method for suppressing noises on a Hearing aid.
- Hearing impaired people often suffer from a reduced ability to communicate in noise.
- To improve the signal / noise ratio are going to be procedures for some time used for noise reduction. This is done in Hearing aids with the help of one or more microphones the acoustic Signal received and electrically processed so that the signal / noise ratio is improved and then via a receiver in the ear canal a suppressed signal can be issued.
- the acoustic signal but also directly, d. H. concurrently to an electric Processing path, enter the ear canal and so the desired Affect the influence of electrical signal processing.
- Typical concurrent signal paths result For example, in hearing aids with open supply or at Earmolds with vent holes.
- the noise reduction based on directional microphone method in low frequency range up to approx. 1 kHz can.
- a generic hearing aid is for example from the Publication DE 198 13 512 A1 known.
- the noise cancellation takes place here under the mentioned impairment.
- the document EP 1 304 902 A1 describes a method for noise immunity of a redundant acoustic Signals in which the intensity of a disturbance is estimated and an input signal component as a function of the intensity the interference is superimposed.
- the object of the present invention is therefore to propose a hearing aid with improved noise reduction. Likewise, an improved method for noise reduction be provided in hearing aids.
- this object is achieved by a hearing aid with an estimating device for estimating a useful signal from a disturbed input signal and a first signal processing device for processing the wanted signal too a Nutzausgangssignal, wherein with the estimator also an interference signal from the disturbed input signal estimated is. Furthermore, the hearing aid has a second signal processing device on, with the transfer function an acoustic path that can be imitated of the interfering signal with the transfer function under formation a disturbance output signal is suitable. Subsequently is a linking device for linking the Nutzausgangssignals needed with the disturbance output signal.
- the invention provides a method for Suppressing noise on a hearing aid Estimating a useful signal from a disturbed input signal and processing the payload signal into a payload output signal, and estimating an interfering signal from the disturbed input signal, Applying the interference signal with a transfer function, with which an acoustic path is modeled, under Formation of a disturbance output signal and linking the Useful output signal with the disturbance output signal.
- the acoustic Path is usually in an ear canal on the hearing aid lead past. This is a relatively short distance, so that it is essential with the second signal processing device as soon as possible a compensating signal to generate the estimated noise. This can be the Sound instillation on the hearing aid over to the eardrum so far be compensated as possible.
- the replicated transfer function may be linear. These reduces the computing time and thus optimizes the noise compensation.
- the transfer function but also be time-varying, so that, for example, the move of the hearing aid in the ear canal are taken into account can.
- the hearing device can have an acoustic sensor, which in the inserted into an ear canal state of Hearing aid on the eardrum facing the end of the hearing aid placeable or placed so that its signal to dynamic variation of the replicated transfer function the second signal processing device can be used. This makes it possible to audible the condition in front of the eardrum to adapt the transfer function by means of a To consider the control loop.
- the hearing device may further comprise a coupling device, with the Nutzausgangssignal the first signal processing device to the second signal processing device for varying the replicated transfer function can be coupled.
- the coupling factor the coupling device set in hearing aid or varied. This is beneficial if that Noise signal is strongly correlated with the useful signal, so that excessive attenuation of the useful signal can be prevented can.
- the hearing aid shown schematically in FIG. 1 has a signal processing device 1 as the central component. This takes the further signal processing of one of the microphone or microphones 2 recorded and freed by the noise canceling device 3 of noise useful signal.
- a useful signal N and an interference signal n are estimated from the input signal from the microphone 2 and from the plurality of microphones. While the estimated useful signal N and is further processed in the signal processing device 1, the estimated interference signal n and an estimated system transfer function H and applied.
- the transfer function H and results from a concurrent, acoustic signal path, which can be represented by a linear acoustic system 5 with a transfer function H.
- the input of the concurrent signal path is the same acoustic signal x , which also accommodates the microphone 2.
- the acoustic signal xH is obtained by multiplication with the transfer function H of the linear acoustic system 5.
- the fact that the concurrent signal path is a linear acoustic system is certainly a simplifying assumption The purpose is to make the signal processing device 4 used for estimating or simulating the concurrent signal path as simple as possible.
- the output signal n andH at the signal processing device 4 with the transfer function H represents an estimate of the interference signal xH which enters the ear canal via the concurrent signal path.
- the interference signal xH and the opposite-phase, estimated interference signal n andH and cancel in the ear canal and the concurrent signal path is compensated, as far as the transit time difference between the acoustic signal path and the electrical signal path allowed.
- the hearing aid of a second embodiment of the present invention is shown schematically in FIG. Compared to the first embodiment of FIG. 1, it is considered in the second embodiment that the linear acoustic system 5 'of the concurrent acoustic signal path is not sufficiently well known in terms of time or at least in the design of the hearing aid. Therefore, the transfer function H at the signal processing device 4 'is also made time-varying. To vary the transfer function H and a microphone 7 or other sensor is used, which is to be inserted into the ear canal. The signal obtained by the microphone is subtracted from the estimated signal n andH and to obtain an error signal for adaptively adjusting the system 4 'with the transfer function H and .
- the adaptive setting of the transfer function H and can be carried out, for example, with an (N) LMS (Normalized Least Mean Square) algorithm as long as the estimated interference signal n is sufficiently uncorrelated with the useful signal at the hearing device output.
- the influence of the useful signal on the adaptation of the filter or the signal processing device 4 'with the transfer function H and can be reduced by selecting the useful signal with a suitably selected one System 8 with the coupling function G is filtered.
- FIG. 3 Such a system is shown in FIG. 3 in a third exemplary embodiment.
- the output signal of the signal processing device 1 is picked up by the coupling device 8 and multiplied by the coupling function G.
- the resulting signal is subtracted from the microphone signal of the microphone 7 in the ear canal and the estimated interference signal n andH and already subtracted therefrom , so that an error signal of the active noise suppression is obtained.
- This error signal is used to vary the transfer function H and in the time-variant signal processing device 4 '.
- a useful signal which passes through the concurrent acoustic signal path in the ear canal, where it would be interpreted as an interference signal is attenuated or suppressed.
- the signal n andH which is fed in phase opposition into the ear canal, compensates for the interference signal components xH of the acoustic signal x in the ear canal.
- the interference suppression by directional microphone interconnections can also be made possible if concurrent signal paths do not allow this in conventional approaches.
