Abstract (en)
[origin: EP0601934A1] In order to protect a volume (2) located inside a room (3) from external noises E, recourse is had to a bank of acoustic sensors (11j) receiving the noise E and located a distance A from the volume and to a bank of acoustic sources (15k) located a distance B less than A from the volume and signals S are applied to these sources, these signals being summations of the double convolution products of the function Ej(t) with two functions fij(t) and gik(-t) which are directly derivable from the pulse responses collected, on the one hand, on the sensors (11j) from pulses emitted by sources (10i) carried by a fictitious barrier (6) delimiting the volume and, on the other hand, on sensors (12i) placed at the same locations as these latter sources (10i), from pulses emitted by the above sources (15k). <IMAGE>
