Patent ID: 8144883

Claim:
A method for adapting a loudspeaker to a specific listening position relative to the loudspeaker by correcting acoustic power radiated by the loudspeaker by means of a correction filter inserted in the signal path through the loudspeaker, the method comprising: (i) measuring, at an actual listening position, a first quantity characterising the acoustic power radiated by the loudspeaker; (ii) measuring, at a reference listening position, a second quantity characterising the acoustic power radiated by the loudspeaker; (iii) using an electronic comparison means to determine a response of a correction filter by a comparison between said first quantity and said second quantity; (iv) implementing said correction filter; and (v) inserting said correction filter in the signal path through the loudspeaker, and wherein said first and second characterising quantities are radiation resistances measured at the actual listening position and the reference listening position, respectively.
