<p>The present invention relates to a method for controlling one or more loudspeakers provided in an enclosure, such as a listening room or an automobile cabin, the method comprising the steps of: (i) providing said one or more loudspeakers (2, 3, 4) with an audio input signal (5) whereby a sound field (10) is generated in the enclosure (1), and determining the corresponding acoustic power output APO(f) emitted from the one or more loudspeakers (2, 3, 4) into said enclosure (1); (ii) determining an acoustic contribution or room gain RG(f) of the enclosure (1) to the generated sound field (10); (iii) optionally determining a listening position interface LPI(f) that characterises a listener's ability to receive sound energy from a sound field at the specific place in the sound Field, in which he is located; and (iv) determining a filter characteristic as a function of the acoustic power output, the acoustic contribution or room gain RG(f) of the enclosure to the sound field in the enclosure and optionally the listening position interface between the sound field at the listening position and a listener placed at this position. The invention furthermore relates to a system for carrying out the above method and specifically to the use of the method and system for obtaining optimal audio reproduction in confined spaces such as automobile cabins.</p> |
