Abstract (en)
[origin: DE10130233A1] Disclosed is a method for masking interference in a reproduced audio signal which is derived from a digital signal, wherein the reproduced audio signal is attenuated according to the data error statistics of the digital signal, characterized in that a replacement signal is superimposed on the attenuated audio signal according to the data error statistics of the digital signal. The inventive method ensures in an advantageous manner that a signal can be acoustically reproduced, even in the case of digital input signals that are subjected to large amounts of interference, whereby the adjusted volume in a correspondingly equipped radio receiver can be realistically estimated for a user at any moment, thereby preventing the user from misjudging the real adjusted reproduction volume which, according to prior art, can otherwise occur when the reception signal is subjected to a large amount of interference as a result of an interruption in the audio reproduction.
