    • The aim of the invention is to control the bass reproduction of audio signals in electroacoustic transducers based on the psychoacoustic principle denoted by the term “virtual pitch” or “residual hearing (hearing of missing fundamental)”, in such a way that the perception of the virtual bass reproduction of the audio signals is improved in relation to prior art. To this end, the reproduction of the low pitched frequencies or basses released in the electroacoustic transducer is controlled by the amplification of the harmonic waves already contained in the audio signals, in the form of a simulation, in such a way that the listener experiences or perceives an improved bass reproduction. The control or simulation can thus be carried out in both a digital manner, by means of a program module in a digital signal processor of an electronic appliance for outputting and/or reproducing audio signals using the electroacoustic transducer, and in an analog manner, by means of a hardware circuit between a digital analog transducer and a final amplifier of the electronic appliance for outputting and/or reproducing audio signals using the electroacoustic transducer.
    • 本发明的目的是基于由虚拟音调或“剩余听觉(缺少基本听觉)”表示的心理声学原理来控制电声换能器中的音频信号的低音再现,使得感知 与现有技术相比,音频信号的虚拟低音再现得到改善。 为此,在电声换能器中释放的低音调频率或低音的再现通过以模拟形式已经包含在音频信号中的谐波的放大来控制,使得听者经历或 感觉到改进的低音再现。 因此,控制或仿真可以通过电子设备的数字信号处理器中的程序模块以数字方式进行,用于使用电声换能器输出和/或再现音频信号,并且以模拟方式通过 在数字模拟换能器和电子设备的最终放大器之间的硬件电路的装置,用于使用电声换能器输出和/或再现音频信号。

    • A method and device are provided for the interference elimination of a redundant acoustic input signal of an acoustic reproducing device, such as a mobile phone or a hearing aid, according to which the interference is concentrated in a partial frequency range of a total frequency range of the input signal. The present invention seeks to improve the sound quality of an acoustic output signal produced. The inventive method includes the following subsequent steps: a) removing the partial frequency range of the input signal, in which the interference is concentrated, b) dividing up the intensity of the frequency range of the input signal that was allowed to pass in the first step into an input signal portion to be maintained and an input signal portion to be further processed, c) synthesizing the partial frequency range of the input signal removed in step a) in accordance with the input signal portion to be further processed, and d) combining the input signal portion from step b) to be maintained and the synthesized input signal portion from step c), thereby producing an output signal that is interference-eliminated as compared to the input signal.

    • A capacitive sensor device has at least one measuring electrode, at least one ground electrode, and an evaluation device being coupled with the at least one measuring electrode and being configured to detect a capacitive coupling between the at least one measuring electrode and a ground of the evaluation device.At least one ground electrode can be galvanically coupled with the ground of the evaluation device via a switch. The switching status of the switch can be changed by the evaluation device. The evaluation device is further adapted to detect a common-mode change of the capacitive coupling between the at least one measuring electrode and the ground of the evaluation device when the switching status of the switch changes. An input device, particularly a keyboard with a capacitive sensor device, as well as a method for operating a capacitive sensor device may be designed accordingly.
