Definitions

  • the invention relates to a hearing aid with a directional microphone system according to the preamble of claim 1. Furthermore, the invention relates to a method for operating such a hearing aid according to the preamble of claim 10.
  • a hearing aid device is understood to mean any device which provides or helps to provide an output signal perceptible by a user as an audible signal, and which has means which help or compensate for an individual hearing loss of the user.
  • these are hearing aids which can be worn on the body or on the head, in particular on or in the ear, and which can be implanted in whole or in part.
  • such devices are also included, whose primary purpose is not to compensate for hearing loss, such as consumer electronics (TVs, hi-fi systems, MP3 players, etc.), or communication devices (mobile phones, PDAs, headsets etc), but over Have means to compensate for an individual hearing loss.
  • a hearing aid system consisting of two hearing aid devices that can be worn on or in the ear, in particular hearing aids, is generally used.
  • a hearing aid device system can also comprise at least one further device, for example an external processor unit that can be worn on the user's body.
  • the external processor unit can serve, for example, for the remote control of the hearing aid device or hearing aid device system, but in addition also fulfill other functions, for example an analysis of the acoustic hearing environment.
  • a hearing aid generally includes an input transducer for receiving an input signal.
  • the input transducer is designed for example as a microphone, which receives an acoustic signal and converts it into an electrical signal.
  • a hearing aid usually includes a signal processing unit for processing and frequency-dependent amplification of the electrical signal.
  • a preferably digital signal processor (DSP) is used, whose operation can be influenced by means of programs or parameters which can be transmitted to the hearing aid.
  • the mode of operation of the signal processing unit can be adapted both to the individual hearing loss of a hearing aid wearer and to the current hearing situation in which the hearing aid is currently being operated.
  • the thus changed electrical signal is finally fed to an output transducer.
  • This is usually designed as a handset, which converts the electrical output signal into an acoustic signal.
  • other embodiments are also possible here, e.g. an implantable output transducer that connects directly to an auditory ossicle and causes it to vibrate.
  • a hearing aid with a classifier which analyzes an incoming microphone signal in the hearing aid and automatically detects the hearing situation in which the hearing aid is currently located, is from the published patent application EP 0 064 042 A1 known. Depending on the detected hearing situation, the parameters relating to the signal processing in the hearing aid device are set automatically.
  • a modern hearing aid usually includes a directional microphone system, through which in particular the speech intelligibility can be improved in various listening situations, eg. As in a conversation in an environment with noise.
  • a directional microphone system comprises at least two microphones, the outputs of which are interconnected and whose output signals are linked together in order to achieve a directivity.
  • an internal signal delay between the two microphone signals different directional characteristics are adjustable.
  • the directivity usually serves the AI-DI (articulation index directivity index).
  • AI-DI articulation index directivity index
  • KEMAR measurements for a specific carrying position of the respective hearing aid device, wherein a reference signal is presented from the frontal direction.
  • the basic time delay is usually adjusted so that a sound signal incident from the front (with respect to the viewing direction) is optimally received and a sound signal incident from the opposite direction (from the rear) is maximally suppressed.
  • a hearing aid with a directional microphone system with two electrically interconnected microphones, in which different directional characteristics are adjustable as a function of a signal delay between the generated microphone signals for example, from the patent US 5,757,933 known.
  • the basic time delay is highly dependent on the effective distance of the two microphones with respect to a sound source, and secondly, the effective base time delay is also due to the frequency dependent diffraction and reflection of the sound frequency dependent.
  • the frequency-dependent basic time delay is normally determined by KEMAR measurements, but it is highly dependent on the reflection characteristics of the hearing aid hearing environment.
  • the first problem is highly relevant for universally fitting (instant fit) hearing aids with fixed hose or cable lengths between the respective hearing aid and an associated earmold. Due to the given hose or cable lengths, the positions of the individually worn hearing aid devices vary more than in a conventional adaptation, because in the latter the acoustician can manually adjust the hose length to the individual ear of the respective user, thereby achieving the ideal position. The more an angle ⁇ between a connecting line of the microphone openings and the horizontal plane in a hearing aid worn by a user deviates from the angle ⁇ determined during the development process on the KEMAR for the optimum wearing position, the more ineffective the directivity of the directional microphone system, i. h., the AI-DI is sinking.
  • the second problem occurs regardless of the wearing position. Individual factors such as the hairstyle or shape of the head and pinna affect the frequency-dependent group delay, thereby impairing the performance of the directional microphone system.
  • the US 2002/0 041 696 A1 discloses a hearing aid with a directional microphone system according to the preamble of claim 1 and a method for operating such a hearing aid according to the preamble of claim 10.
  • the US Pat. No. 7,340,068 B2 discloses an apparatus and method for determining wind noise in which a first time dependent correlation signal consisting of values of a cross correlation function between a first and a second microphone signal and a second time dependent correlation signal are generated from values of an auto cross correlation function of either the first or the second second microphone signal.
  • the object of the present invention is high performance to achieve a directional microphone system in a hearing aid, regardless of the individual carrying position of the hearing aid.
  • the basic idea of the invention is to determine, by means of a cross-correlation analysis, the time delay with which an acoustic signal arrives at the microphones, in particular the microphone opening assigned to the respective microphone in the housing of the hearing aid.
  • the internal time delay in at least one microphone signal generated by one of the two microphones then takes place as a function of the external delay determined by means of the correlation analysis.
  • the invention makes it possible to adapt the internal delay to the individual, dependent on the wear position external delay.
  • an optimized with respect to the individual carrying position directivity can be adjusted. Even with a deviation of the individual wearing position from the ideal wearing position, a high performance of the respective directional microphone system, in particular a high AI-DI, is achieved.
  • the hearing aid according to the invention comprises a classifier for determining the hearing situation in which the hearing aid is currently located, wherein the adjustment of the time delay in dependence on the hearing situation.
  • the determination of the effective distance of the microphones of the respective directional microphone system is particularly useful if the position of the acoustic sound source, from which an acoustic signal emanates and is detected by the microphones, is known in relation to the microphones. This can be assumed in certain listening situations. For example is in the listening situation "conversation at rest” assumed that the hearing aid wearer is facing the interlocutor. This is therefore an ideal time to determine the effective distance between the microphones. In addition to the listening situation “conversation in peace", however, this also applies to other listening situations, for example "television".
  • the determination of the time delay with which an acoustic signal arrives at the microphones by means of a cross-correlation function.
  • This is commonly used in signal analysis to describe the correlation of two signals x (t) and y (t) at different time shifts ⁇ between the two signals. It shows, for example, maxima in the case of time shifts which correspond to the signal propagation time from the measuring location of the signal x (t) to the measuring location of the signal y (t).
  • runtime differences from one signal source to both measurement locations can be determined in this way.
  • the cross-correlation function of the microphone signals has a maximum at a time delay ⁇ which corresponds to the transit time of the acoustic signal between the two microphones (that is, between the two microphone openings in the housing of the hearing aid). This time delay is referred to as the effective time delay ⁇ eff .
  • the effective external transit time of an acoustic signal between the two microphones arriving from the user's point of view from the frontal direction into the hearing aid device carried in the individual position can be determined in a simple manner.
  • the internal time delay between the microphone signals is not adjusted due to a single determination of the cross-correlation function of the two microphone signals and thus a one-time calculation of the effective time delay ⁇ eff . Rather, it is advantageously carried out within a certain period of time a repeated determination of the cross-correlation function and thus the effective time delay ⁇ eff .
  • a histogram analysis From this a resulting effective time delay ⁇ eff , res is determined. This results in stable results.
  • the time shift ⁇ is divided into specific time ranges and the frequency with which the effective time delay ⁇ eff falls within this time range is determined for each time range. From the time range in which the determined effective time delays ⁇ eff are most frequent, the resulting effective time delay ⁇ eff , res results.
  • a behind the ear portable hearing aid with a directional microphone system with a front and a rear microphone is advantageously the internal (base) time delay of the microphone signal generated by the rear microphone equal to the determined in the manner described above effective time delay ⁇ eff or resulting effective time delay ⁇ eff , res set.
  • This is the basic time delay, which largely extinguishes an acoustic signal coming from behind the hearing aid wearer (cardioid characteristic).
  • a time delay different from the base time delay may also be set.
  • a directional microphone system with two microphones for example, a super-cardioid, a hyper-cardioid or even an "eight" characteristic can be set.
  • a preferred embodiment of the invention provides to determine an also time-dependent internal time delay. This can be achieved in a simple manner in that the microphone signals emanating from the microphone signals are first each supplied to a filter bank. Through this, a splitting of the microphone signals into frequency bands. The internal time delay is then determined separately for the respective frequency band. As a result, the influence of diffraction and reflection phenomena largely suppress.
  • the calculated effective time delay or resulting effective time delay is first subjected to a plausibility check before the internal time delay is adjusted.
  • erroneous values with regard to the effective time delay can be determined.
  • threshold values can be set for the calculated effective time delay, beyond which no adjustment of the internal time delay takes place.
  • Another possibility is to perform a comparison of the determined in both hearing aid devices effective time delays in a hearing aid device system with two worn on the head hearing aids. If these time delays differ too much from one another, this indicates a hearing situation which is not suitable for the setting according to the invention.

  • the signal processing in the signal processing unit parameters are adjusted automatically to adapt the signal processing to the detected hearing situation.
  • FIG. 2 is the usual structure of a directional microphone system used in hearing aids with two microphones F (front) and B (back) visible.
  • the microphones F and B usually have a distance between 5 mm and 15 mm and are equally sensitive in all directions (omnidirectional).
  • the microphones F and B are electrically interconnected, thereby linking the microphone signals generated by them together.
  • the microphone signal SB generated by the rear microphone B usually becomes a delay element T is delayed by an internal time delay T i and subtracted from the microphone signal SF generated by the front microphone F.
  • the subtraction is usually realized by an inverter I in conjunction with a summation element S.
  • the microphone signal SB originating from the rear microphone B is inverted and added to the microphone signal SF originating from the front microphone F. This produces the directional microphone signal SD at the output of the summation element S.
  • the internal time delay T i is set to correspond to the propagation time of an acoustic signal between the two microphones F and B (base time delay)
  • the acoustic signal of a signal source on the line connecting the two microphones will be least attenuated when the signal source is located in front of the front microphone F, and maximally attenuated when the signal source is behind the rear microphone B.
  • the internal time delay T i By varying the internal time delay T i , the direction of the maximum attenuation can be pivoted in space in a known manner.
  • directional characteristics such as "cardioid characteristic”, “super cardioid characteristic”, “hyper cardioid characteristic”, “eight characteristic” etc can be set.
  • the invention is not limited to the shown conventional embodiment of a directional microphone system for a hearing aid. Rather, this analog is also applicable to other interconnections of microphones and directional microphone systems with more than two microphones.
  • FIG. 3 serves to explain the effects of a relation to an ideal position changed position of a worn on the head of a user hearing aid or its directional microphone system.
  • a sound source in front of the front microphone F is on a straight line through the two microphones F and B.
  • the sound first hits the front microphone F and around the delay time, which the sound for the distance d between the two microphones F and B requires, is delayed at the rear microphone B.
  • the internal delay T i (cf. FIG. 2 ) is then set to correspond to the duration of the sound to overcome the distance d.
  • a time delay resulting from the effective distance d eff is automatically determined and set.
  • the microphones of the directional microphone system are not in a horizontal plane, but that even with the ideal carrying position a straight line through the microphones includes a predetermined angle ⁇ with the horizontal.
