Definitions

  • the invention relates to a method for operating a hearing aid device having two hearing devices, which are signal-technically coupled to one another.

  • the hearing aids listed by way of example are worn on the outer ear or in the auditory canal of a hearing aid user.
  • bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
  • Such hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
  • the input transducer is typically an acousto-electrical transducer, such as a microphone, and / or an electromagnetic receiver, such as an induction coil or (radio frequency, RF) antenna.
  • the output transducer is usually used as an electro-acoustic transducer, for example as a miniature speaker (listener), or as an electromechanical transducer, such as a bone conduction handset, realized.
  • the amplifier is usually integrated in a signal processing device.
  • the power is usually supplied by a battery or a rechargeable battery.
  • a so-called binaural hearing aid device two such hearing aids are worn by a user, wherein there is a communication link between the hearing aids.
  • data possibly even large amounts of data, are exchanged wirelessly between the hearing device on the right and left ear during operation.
  • the exchanged data and information allow a particularly effective adaptation of the hearing aids to a respective acoustic situation. In particular, this allows a particularly authentic surround sound for the user and improves the understanding of speech, even in noisy environments.
  • Hearing aids are preferably designed to be particularly space-saving and compact, so that they can be visually worn as inconspicuously by a Hör Schuvoriquessnutzer.
  • increasingly smaller hearing aids are manufactured, which have an increasingly higher wearing comfort, and are thus hardly noticed by a user when worn on or in an ear.
  • this also increasingly creates the danger that a hearing aid unnoticed by a user falls down while wearing and is thus lost.
  • From the EP 2 150 076 B1 is a binaural hearing aid device with two hearing aids known, which are signal-technically coupled by means of a radio link.
  • the hearing aids in each case monitor a signal level of the radio link. If a hearing aid falls down, the radio link breaks off, whereupon the other hearing aid automatically generates an information signal that can be perceived by the user. As a result, a Verlierstik the hearing aids is realized.
  • the EP 2 109 331 B1 describes a hearing aid with a fall protection, wherein an acceleration sensor of the hearing aid falls on the basis of a jerky acceleration of the hearing device detected. In the event of a fall, the current settings of the hearing aid are stored in a memory.
  • EP 2 908 549 A1 shows a similar procedure in a binaural hearing aid system.
  • the EP 3 035 710 A2 relates to a monitoring system for one or more hearing aids.
  • the monitoring system has a number of access points, which are designed to receive wireless radio signals of the hearing aids.
  • the access points are coupled to each other via the Internet or a cloud of clouds.
  • the monitoring system automatically monitors the status of one or more parameters of the hearing aids.
  • the hearing aids here have, for example, acceleration sensors whose measured values are monitored as parameters.
  • the WO 2014/184395 A2 describes a binaural hearing aid with two hearing aids, which are coupled by means of a Bluetooth communication link with a short range.
  • the hearing aids are further adapted to be coupled by means of a second Bluetooth communication link with a relatively large range with an external device.
  • the invention has for its object to provide a particularly suitable method for operating a hearing aid.
  • the invention is further based on the object of specifying a hearing aid device which can be operated according to such a method.
  • the inventive method is suitable for operating a hearing aid device with two hearing aids (hearing aids) and set up.
  • the hearing aids are preferably each worn on an ear of a user.
  • the hearing aids of the particular binaural hearing aid device are by means of a wireless first communication link coupled with a comparatively short range and by means of a wireless second communication connection with comparatively long range signal technology. This means that the second communication connection has a higher range than the first communication connection.
  • a range here is to be understood in particular the signal range, ie a distance of the respective communication link, which may be maximum between a transmitter and a receiver, so that even a communication between them is possible.
  • the hearing aids expediently have corresponding transceivers (transceivers) for the communication connections.
  • the communication connections are preferably designed bidirectionally for mutually alternating signal transmission between the hearing aids.
  • a relatively short range of the first communication connection is to be understood as meaning, in particular, a signal connection between the hearing aids, which breaks off, for example, at a relative distance between the hearing aids of approximately 50 cm to 1 m.
  • the comparatively long range of the second communication connection is preferably associated with a signal connection between the hearing aids, which, for example, breaks off at a relative distance between the hearing aids of approximately 10 m.
  • the two hearing aids each have an integrated motion sensor for detecting a fall of the respective hearing aid.
  • the motion sensor is embodied, for example, as an acceleration sensor, preferably as a three-axis acceleration sensor, which detects the acceleration of the fall during the fall and / or the jerky acceleration in the case of an emergence of the hearing aid on a ground. Additionally or alternatively, it is also conceivable that a gyroscopic (position) sensor is used, which detects a fall due to an unusual rotation of the hearing aid.
  • a first signal level of the first communication link is monitored as a measure of the signal strength between the hearing aids and with a stored first threshold is compared.
  • a notification signal is sent via the second communication connection by a first of the two hearing aids if its motion sensor detects a fall and the first signal level reaches or falls below the first threshold value.
  • Achieving or falling short of the first threshold corresponds essentially to tearing off the first short-range communication connection between the two hearing aids.
  • tearing off is to be understood as meaning, in particular, an interruption, disconnection or other disturbance of the communication connection, which essentially prevents signal transmission between the hearing aids.
  • the second of the two hearing aids Upon receipt of the notification signal, the second of the two hearing aids generates a user-perceivable first information signal as loss protection. As a result, the user is signaled falling down of the first hearing device during wear, so that the risk of unnoticed loss of the hearing aid is advantageously reduced. Thus, a particularly suitable method for operating a hearing aid device is realized.
  • the hearing aids are coupled to one another by means of two wireless communication links of different ranges.
  • the second hearing device does not generate the information signal when the first communication connection is disconnected, but only when it receives the notification signal from the first hearing device via the second communication connection.
  • the triggering of the loss signaling therefore ensues on the basis of the first hearing device, that is, the one which has fallen down or is lost, so that the additional information of the motion sensor is taken into account.
  • Both hearing aids register the demolition of the first communication connection substantially simultaneously, but only the falling (first) hearing aid detects a fall by means of the motion sensor. In other words, it can be unambiguously determined which of the two hearing aids is lost; this would not be clearly identifiable by the hearing aids with a mere tearing off of the first communication connection itself.
  • the detection of the camber by means of the motion sensor is additionally used as a triggering criterion for the first information signal.
  • the detected by the motion sensor movement of the hearing aid has, for example, a much lower acceleration at a deliberate drop as in a fall during an accidental fall.
  • the hearing devices preferably each have a controller (that is to say a control device), for example as part of a signal processing device.
  • the controllers of the hearing aids are here generally - program and / or circuitry - set up to carry out the method described above according to the invention.
  • the controllers are thus in particular configured to perform a threshold comparison of the first signal level and to evaluate a sensor signal of the motion sensor in the event of a fall and to send the notification signal in dependence thereon.
  • the controllers are configured, upon receipt of the notification signal, to effect the information signal for signaling to the user.

  • ASIC application-specific integrated circuit
  • the notification signal is sent when the detection of a fall and the reaching or falling below the first threshold within a predetermined period of time. This takes into account the fact that the detection of the fall and the tearing off of the first communication connection do not necessarily take place at the same time. This is the case, for example, if the hearing device briefly latches on a user's clothing when it falls down or if the user consciously removes the hearing device and it falls down.
  • the detection of the fall and the tearing off of the first communication connection should have a short temporal proximity, so that the time duration in a possible further development form is dimensioned to a few seconds.
  • the signaling by means of the information signal takes place as soon as possible, so that the user has not yet moved far away from the fallen hearing aid. This makes it easier for the user to find the (first) hearing device.
  • an acoustic notification is generated by the second hearing device as a first information signal.
  • the acoustic notification is in this case designed, for example, as a signal tone or a tone sequence or as a voice message.
  • the acoustic notification is here suitably generated by means of an output transducer or loudspeaker (receiver) of the second hearing device. This allows for easy perceptible signaling to the user.

  • a third information signal is generated with the application software of the operating and display device when the second signal level reaches or falls below the second threshold value.
  • the first (short-range) communication connection is interrupted, whereupon the first hearing device sends the notification signal via the second (long-range) communication connection to the second hearing device and to the operating and display device.
  • the loss is signaled while the user is still in a close environment around the first hearing aid.
  • This close environment is essentially limited by the range of the second communication link, so that it is ensured by the operator and display device-side monitoring of the signal level of the second communication link that the user does not move unintentionally out of this environment.
  • the third information signal is embodied, in particular, as an alarm signal which signals to the user that he is moving away from the first hearing device.

  • a distance value determinable from this can be displayed by the application software on the display or display of the operating and display device, so that the user can search for the first hearing aid is further simplified. As a result, the user generally requires no further aids for finding the first hearing device.
  • the operating and display device after receiving the notification signal of the first hearing device, the operating and display device checks whether the notification signal has been received by the second hearing device. In this case, a further or additional notification signal is sent from the operating and display device by means of the second communication connection to the second hearing device when no acknowledgment of the notification signal is sent by the second hearing device.

  • the position x is stored by the application software 34 in a memory of the smartphone 30.
  • the position x thus corresponds to the immediate vicinity of the lost hearing aid 4b.
  • the application software 34 monitors a signal level P2 of the communication connection 8, that is to say the signal strength between the smartphone 30 and the hearing device 4a.
  • the signal level P2 is here compared in a threshold comparison 56 with a stored second threshold W2.
  • the application software 34 starts a method step 58.
  • an information signal 13 is generated.
  • the information signal 13 signals a user as a warning signal that he is moving away from the hearing aid 4b.
  • the threshold value W2 is in this case preferably dimensioned such that it corresponds to a relative distance or a distance between the smartphone 30 and the hearing aid 4b, which is lower than the range R2.
  • the information or warning signal l3 is triggered before the user has moved further away from the lost hearing aid 4b than the range R2.
  • the smartphone 30 By evaluating the signal level P2, the smartphone 30 thus effectively acts as a proximity sensor for the hearing aid 4b.
  • the stored position x together with a through the device 54 by means of the application software 34 preferably at any time retrievable, so that, for example, on the touch screen 32, a numerical value for the relative distance and / or a direction indication to the hearing aid 4b are displayed.
  • the method 36 realizes reliable and accurate protection against loss for the hearing aids 4a and 4b.
  • a particularly suitable method for avoiding a loss of hearing aid and for finding a lost hearing aid results.
