  • Publication number: 20080175401
    Abstract: The acoustic properties of so-called instant fit ear tips, which in contrast to otoplastics are not produced individually, should be able to be better taken into consideration when adjusting a hearing aid for an individual wearer. To this end a method is proposed in which an OLG measurement, in other words an open loop gain measurement, is performed on the hearing aid when it is being worn. The OLG measurement curve obtained is compared with an OLG reference curve. A value is ascertained from the comparison which represents the level of closure of the hearing aid or of its otoplastic in the ear of the wearer. On the basis of this value the gain of the hearing aid is finally corrected. Furthermore, a corresponding adjustment device is provided. It is thus possible in a simple manner to take into consideration the individual, current level of closure during the adjustment.

  • Publication number: 20080130925
    Abstract: A method for processing at least one first and one second input signal in a hearing aid, with the input signals being filtered to create intermediate signals, the intermediate signals being added to form output signals, the input signals being assigned to a defined signal situation, and with the signals being filtered as a function of the assigned defined signal situation.

  • Publication number: 20080123880
    Abstract: Method for processing an input signal in a hearing aid, with the input signal being broken down into a discrete signal for each source relative to an acoustic signal, with the discrete signals being assigned to a spatial position of the source and with the discrete signals being output, or output attenuated, relative to the spatial position.

  • Publication number: 20080107297
    Abstract: A “speaker” operating mode is established by a signal processor of a hearing aid for tracking and selecting an acoustic speaker source in an ambient sound. Electric acoustic signals are generated by the hearing aid from the ambient sound that has been picked up, from which signals an electric speaker signal is selected by the signal processor by a database of speech profiles of preferred speakers. The electric speech signal is selectively taken into account in an output sound of the hearing aid in such a way that it will for the hearing-aid wearer acoustically at least be prominent compared with another acoustic source and consequently be better perceived by the hearing-aid wearer.

  • Publication number: 20080086309
    Abstract: A “speech” operating mode is established by a signal processor of a hearing aid for tracking and selecting an acoustic speech source in an ambient sound. The electric acoustic signals are generated by the hearing aid from the ambient sound that has been picked up, from which signals an electric speech signal very probably containing speech is identified and selected by the signal-processor, and the electric speech signal is selectively taken into account in an output sound of the hearing aid in such a way that it will for the hearing-aid wearer acoustically at least be prominent compared with another acoustic source and consequently be better perceived by the hearing-aid wearer.

  • Publication number: 20070269067
    Abstract: A hearing device and method for monitoring the hearing ability of a person with impaired hearing allow changes of the hearing ability specifically of a person wearing a hearing aid are to be better able to be registered and taken into account. For this purpose, the setting of an operating element, this serves for setting an output sound level of a hearing device. Furthermore, the ambient sound level in the vicinity of the hearing device is measured. After that, the current setting is compared with the current, measured ambient sound level and a corresponding control signal is output dependent on the result of the comparison. This control signal serves, for example, for signaling to the wearer of a hearing aid the loss of hearing or the automatic adjustment of the hearing aid.

  • Publication number: 20050105750
    Abstract: The training of a hearing aid for individual Situations is intended to be simpler and more comprehensive for the hearing aid wearer. The invention therefore provides for the hear-ing aid wearer just to have to associate a current ac oustic Situation with a predetermined hearing Situation identification (3?). This association is learnt by a classifier, for example a neural network (5). After the training process, the neural network (5) can then reliably associate the corresponding hearing Situation identification (3?) with an acoustic input Signal (2). A current Parameter Set (4?) is varied or supplemented appropriately on the basis of this association.

  • Publication number: 20040208330
    Abstract: If a hearing device user has become accustomed to the tone of a hearing device, it is difficult for him to change over to a new hearing device, since this normally possesses a different tone. Therefore, given a treatment with a second or subsequent device, the settings of the old hearing device can be acquired with a computer-controlled event and be considered in a first adjustment given the adaptation of the new hearing device. The new setting then results from the audiometric measurements, the data of the previous device, and if necessary further data. The tone of the new device is thus approximated to the old device.
