    • The invention relates to a method for operating a hearing system comprising an input unit, an output unit and a transmission unit operationally interconnecting said input output units. Said transmission unit implements a transfer function describing, how audio signals generated by said input unit are processed in order to derive audio signals fed to said output unit, and can be adjusted by one or more transfer function parameters. Said method comprises obtaining, by means of said input unit and with a first directional characteristic, first audio signals from incoming acoustic sound; deriving from said first audio signals a first set of sound-characterizing data; and deriving, in dependence of first directional information, which is data comprising information on said first directional characteristic, and of said first set of sound-characterizing data, a value for each of said one or more transfer function parameters. This allows to gain insight into the acoustic environment and allows for better automatic adjustments of said transfer function.

    • In a signal processing unit of a hearing device, the signal processing unit consisting of a signal analyzing unit and a signal identification unit, the momentary acoustic surround situation is identified. Based on this identified surround situation, the parameter set belonging to the identified surround situation is automatically adjusted in a transmission unit in which a number of parameter sets are saved which are assigned to different acoustic surround situation. The hearing device user can adjust his individual hearing desire for each acoustic surround situation according to the automatic adjusted parameter set with the aid of an input unit. Thereby, the parameter of this parameter set are adjusted at the same time and commonly in one of two opposing directions, e.g. in the sense of “better hearing” or in the sense of “more pleasant understanding”.
    • 在听力装置的信号处理单元中,由信号分析单元和信号识别单元组成的信号处理单元识别出瞬时声环绕状态。 基于该识别的环绕情况,属于所识别的环绕情况的参数集在保存了分配给不同声环境的参数组的传输单元中被自动调整。 听力设备用户可以根据通过输入单元设置的自动调节参数来调整每个声环绕情况的个人听力需求。 因此,该参数集的参数在两个相反的方向中的一个方向上同时并且通常地被调整。 在“更好的听觉”或“更愉快的理解”的意义上。

    • In a digital hearing aid device (1) frequency modification is employed above a lower spectral bound and in accordance with a compression factor. The frequency modification is dynamically adjusted in dependence on a sound environment analysis (10) or an end-user input (30), by modifying the frequency modification parameters such as a lower spectral bound and a compression factor. The adjustment can be based on an interpolation between predefined parameters. In certain sound environments, such as loud noise, own-voice and telephone conversations, frequency modification is reduced or switched off. The proposed solutions have the advantage that the occurrence of disturbing noise and of distortions of harmonic relationships at the end-user's ear is reduced and signal processing resources as well as battery resources are saved.
    • 在数字助听器装置(1)中,在较低频谱界限之下并根据压缩因子采用频率修改。 根据声音环境分析(10)或最终用户输入(30),通过修改诸如较低频谱边界和压缩因子的频率修改参数来动态调整频率修改。 调整可以基于预定义参数之间的内插。 在某些声音环境中,例如大噪声,自己的语音和电话对话,频率修改被减少或关闭。 所提出的解决方案的优点在于减少了最终用户耳朵处的干扰噪声和谐波关系失真的发生,并且节省了信号处理资源以及电池资源。
