Definitions

  • the present invention relates to a method for synchronizing signal sounds that are output by the hearing aids in the case of a binaural hearing aid supply.
  • the present invention relates to a corresponding hearing aid system for binaural care or a corresponding hearing aid.
  • Wirelessly connected hearing aid systems enable communication between the right and left hearing aid in the case of binaural care.
  • wirelessly received instructions such as program switching
  • the acoustic output is not synchronized in both hearing aids.
  • a time offset is particularly noticeable in the output of beeps ("Beeps").
  • the object of the present invention is thus to propose a simple synchronization of hearing aids for the sound signal output.
  • this object is achieved by a method for synchronizing signal sounds which are output by the hearing aids in the case of a binaural hearing aid device, by sending a synchronization signal from a first of the hearing aids, in which a first counter is continuously counted up or down, to a second one of the hearing aids Setting a second counter, which is continuously counted up or down, in the second hearing aid to the count of the first counter in response to the synchronization signal, taking into account a predetermined signal delay between the two hearing aids, sending a control signal with a count or before a predetermined count, in which in each case a signal tone is to be emitted by the first hearing device and by the second hearing device, from the first hearing device to the second hearing device and emitting a respective beep from the two hearing aids, if the respective counter is the Z hlwert reached.
  • a corresponding hearing aid system for binaural supply with a first hearing aid comprising a transmitting unit for transmitting a synchronization signal and for transmitting a control signal with a count value or before a predetermined count value at which a signal tone is to be delivered, and a first counter, the is continuously counted up or down, a second hearing aid having a second counter, which is continuously counted up or down, a receiving unit for receiving the synchronization signal from the first hearing aid and for receiving the control signal and a setting unit for setting the second counter having the count of the first counter in response to the synchronization signal, taking into account a predetermined signal delay between the two hearing aids, wherein each of the two hearing aids a beep is issued when the respective counter Zählw reached.
  • the second counter is reset when setting to a predetermined value, since Also, the first counter is reset to the predetermined value taking into account the duration of the synchronization signal for synchronization.
  • a defined value e.g. B. zero
  • a method for synchronizing beeps which are output from the hearing aids in binaural hearing aid supply, by sending a synchronization signal from a first of the hearing aids, in which a first counter is continuously counted up or down, together with the current count of the first counter to a second of the hearing aids, sending a synchronization signal from the second hearing aid, in which a second counter is continuously counted up or down, along with the current count of the second counter to the first hearing aid, receiving the count of the respective other Hearing device, storing a difference value between the received and the own count in each of the hearing aids, taking into account a predetermined signal delay between the two hearing aids, sending a control signal with a count, in which of the second hearing aid Si gnalton, from the first hearing aid to the second hearing aid and outputting a beep from the second hearing aid when the second counter has reached the count and emitting a beep from the first hearing aid when the first counter is one by the difference value from the
  • a hearing aid for binaural supply with a counter which is continuously counted up or down, a transmitting unit for transmitting a synchronization signal together with the current count of the counter, a receiving unit for receiving the count of another hearing aid, a memory unit for storing a Difference between the received and the own meter reading taking into account a predetermined Signal propagation time between the two hearing aids and a signal output unit for outputting a signal when the counter has reached a predetermined count, wherein from the transmitting unit, a control signal with a value different from the difference value to the other hearing aid is transferable, so that the other hearing aid can emit a signal when the counter of the other hearing aid reaches the value.
  • the hearing aids in this second solution are completely equal to each other. Therefore, no different designs are required for the hearing aids.
  • each counter may represent a clock and the counts absolute times or periods.
  • the beep outputs can be oriented, for example, to a specific daily rhythm.
  • the synchronization signals are sent at regular time intervals to the slave hearing device or to the respective other hearing aid. This is favorable insofar as the quality of the individual meters does not have to be so demanding because they are always matched to one another.
  • An inventive binaural hearing system consists of a left hearing aid HG1 and a right hearing aid HG2. Between two hearing aids HG1 and HG2, a preferably low-speed data connection for the transmission of control or synchronization signals is constructed. This data connection satisfies low demands and only intermittent and not necessarily continuous signals are exchanged.
  • the hearing aid HG1 has a signal processing SV1, which serves in addition to the usual signal evaluation for transmitting and receiving signals between the hearing aids HG1 and HG2. In addition, it controls a speaker L1, among other things, to emit a beep. Furthermore, the signal processing unit SV1 sets a counter Z1 and reads it out.
  • the hearing aid HG2 is constructed practically identical to the components signal processing SV2, loudspeaker L2 and counter Z2.
  • the hearing aid HG2 can be dispensed with a transmitting unit when it is used as a pure slave hearing aid.
  • the aim is to carry out signal outputs on the right and left hearing aid exactly at the same time or with a precisely predetermined time offset.
  • a clock in the form of a continuously running in the clock digital counter Z1, Z2 is present in each hearing aid.
  • the hearing aid HG1 controls the communication connection as a so-called "master" between both hearing aids.
  • the hearing aid HG1 sends a synchronization signal S according to FIG 2 to the hearing aid HG2.
  • the counters Z1 and Z2 are reset to their initial value in both devices HG1 and HG2 and thus run synchronously.
  • the reset of the counter or the clock in the hearing aid HG1 takes place here by a delay time T compared to the sending of the synchronization signal S.
  • the delay time T is composed of the signal delay time between the two devices and the processing time of the synchronization signal S.
  • the synchronization of the counters Z1 and Z2 is similar to the first embodiment, but the synchronization signal S additionally contains the absolute time / counter reading of the counter Z1.
  • the hearing aid HG2 then sets its time or its counter reading to the received time / counter reading. After the abovementioned delay time T, the two counters Z1 and Z2 therefore also have the same counter reading and are thus synchronized.
  • the two hearing aids HG1 and HG2 are equal.
  • a memory location for storing a digital numerical value is present in each hearing aid.
  • the counters are started independently of each other.
  • Both devices HG1 and HG2 send for synchronization to the other synchronization signals. These signals each contain the time / counter reading of the sending device.
  • the receiving device calculates from the own time / the own counter reading at the time of receipt and the received time / count value, corrected by the delay time T, a difference value and stores it.
  • T delay time
  • the synchronization thus takes place here indirectly in that the difference of the times / counter readings is taken into account in the signal output.
  • the counters Z1 and Z2 of the two hearing aids HG1 and HG2 are now synchronized in accordance with the exemplary embodiments described above. Consequently, processing steps or signal outputs on both devices can now be performed simultaneously.
  • This is done according to a first scheme using an explicit time specification.
  • the hearing aid HG1 initiates an action which is to start simultaneously in both hearing aids.
  • the absolute time specification / absolute counter reading in the future, at which the action is to begin is transmitted to the hearing aid HG2 in a control signal K (see FIG.
  • Both hearing aids HG1 and HG2 compare this time with their current time / their current count and start the action at the specified time.
  • the hearing aids are to output a signal tone when the meter reading 100 is reached.
  • the hearing aid HG1 must initiate this sound output at the latest the delay time period T before the count 100, so that the hearing aid HG2 can respond in good time.
  • the simultaneous signal output by implicit time can only be started to determine previously known times.
  • the hearing aid HG1 which initiates an action, sends the corresponding command K in good time before the next possible start time, so that the hearing aid HG2 can receive and process this command in good time before the next start time.
  • Both devices then start the action at the same time to the next on the send or the Receiving the command following start time.
  • This method requires no known processing time for the initialization of an action in the hearing aid HG2. It is only necessary to be able to estimate a maximum processing time. Nevertheless, the processing time for the initialization of the counters must be known.
