Abstract (en)
[origin: DE10012868C1] The computer includes a digital processor for acoustic data, a device for preparing the data for output, and a device for converting the data into analogue form for output via one or more of the multiple output paths, and for converting into digital acoustic data input analogue acoustic data from a first acoustic transducer transmitted via at least one of the multiple input paths. At least one second acoustic transducer is provided for detecting analogue signals. At least one of the output paths is connected to at least one of the input paths. The digital processor includes the functions of acoustic echo elimination circuit (F) connected at its input to the input path that is connected to an output path, and at its output to an input path that is connected to a second acoustic transducer (e.g. M).
