Abstract (en)
[origin: EP1519618A1] The operating method has audio signals (8.1-8.3) transmitted by the communications device (13.1,13.2), with reception of the audio signals after reflection, for determining an algorithm (5) corresponding to the pulse response of the environment (9), the superimposed noise components resulting from the environment within audio signals (15.1-15.3) received from an external sound source, e.g. the user of the communications device (15), compensated via a corresponding noise suppression algorithm (16). An independent claim for a communications device with audio signal noise suppression is also included.
