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.

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.

System and method for the registration of a mobile part (MT, OA, HA) in a base station (BS) in a telecommunication system designed for wireless communication between a mobile part (MT, OA, HA) and a base station (BS. The base station and the mobile part are initially placed in an access standby state. Subsequently, a verification procedure determines a message exchange (MA) between the mobile part and the base station if the base station supports a voice-controlled registration and if the mobile part is theoretically connected to the base station. If the theoretical connection is determined, a user channel connection suitable for the transmission of voice data is established between the mobile part and the base station. The mobile part is then either registered in the base station, or the registration attempt is rejected.

In order to record and to process audio signals with a good useful-signal to noise-signal ratio in acoustic noise conditions and with a good ratio between the direct sound and the reflected sound in an environment which in particular has no reverberation electrical signals produced by conversion of audio signals recorded by a predetermined microphone arrangement are processed in such a manner that, if the sound pressure levels at the microphones in the microphone arrangement are the same, electrical signals which are produced by these microphones but are of different intensity—different sensitivities of the microphones—are automatically matched, without any manual matching procedures needed to be carried out individually and separately. A microphone arrangement is based on combining the characteristics of an array of microphones with those of a method for matching the sensitivity of microphones.

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.

A speaker-dependent speech recognition method is provided involving the use of a speech recognition system, during which voice utterances of the user are trained, and commands are assigned to the trained voice utterances. The present disclosure seeks to carry out a training of new commands in a time-saving manner. To this end, in the event of a non-recognition of a voice utterance, the speech recognition system provides the user with the opportunity to immediately assign the voice utterance to a new command.
