The invention relates to a method for reproducing audio in a multi-channel sound system including two input signals (L and R), wherein output signals are generated for different sound perception levels. In order to develop said method in such a way that audio can be reproduced within a larger range of applications in a multi-channel sound system, according to the invention, only a lower sound perception level (7) and a higher sound perception level (6) are generated, and a maximum of six output signals are generated, a maximum of two output signals being allocated to the lower sound perception level (7) and a maximum of four output signals being allocated to the higher sound perception level (6).

The invention relates to a securing means and a method for securing a civil engineering element to a construction machine by means of a flexible securing element, wherein a first end of the flexible securing element is attached to the construction machine and a second end is provided with a connecting link which can pass through a securing lug on the civil engineering element and can be releasably fastened to the construction machine by a connecting means. According to the invention, a detection unit is provided on the connecting means, which detection unit is designed for identifying fastening of the connecting link to the connecting means. The detection unit can generate and output a signal if fastening of the connecting link is identified.
