A system for the localization of acoustic signals in a real space, with a mobile device, with a) an interface for acoustic signals or/and a headphone with two loudspeakers (111, 113), b) a positioning module for generating position data and orientation data as a function of the position and orientation of the headphones in a real space, with a receiver for receiving position signals, the receiver being designed for receiving position signals based on ultra-wideband technology, c) a memory for storing acoustic source signals and object position data and/or object orientation data associated with the acoustic source signals in a virtual space, d) a processor adapted to i) receive the position data and the orientation data from the positioning module, ii) read the acoustic source signals and the object position data and/or object orientation data associated with the acoustic source signals from the memory iii) depending on the position data, the orientation data, the object position data and/or the object orientation data, outputting acoustic object signals corresponding to the stored acoustic source signals to the interface or/and the headphones in such a manner that the stored acoustic source signals appear to be acoustically located to a listener wearing headphones fed with the acoustic signals in accordance with the associated object position data and/or object orientation data, and a transmitter (401, 402, 403) in the real space, which is arranged to communicate with the mobile device (101, 102, 103) for generating the position data, wherein, for a film shown on a display surface, the mobile device outputs the sound associated with the film as acoustic object signals in such a way that the sound appears to be associated with a location of the display surface at which the sound appears to originate and/or that the intensity of the sound is dependent on the position or the distance of the mobile device from the display surface, in particular to a location of the display surface at which the sound appears to originate, wherein the processor is arranged to receive a signal and to output the acoustic object signals (210, 211) in accordance with the signal, wherein the signal is a synchronization signal and enables synchronization of the output of the acoustic object signals (210, 211) with the output of moving image documents. a) an
