Abstract

Each device in a set of signal relaying devices (D1, D2, D3) acquires a respective instance (A1<s>, A2<s>, A3<s>) of an acoustic source signal (A) emitted from a noise pollution source (S), produces a respective feedforward signal (s1, s2, s3) comprising the respective instance (A1<s>, A2<s>, A3<s>) together with information designating a respective position (P1, P2, P3) of the device and time-stamp data (t<1>, t<2>, t<3>) to indicate when and where the respective instance (A1<s>, A2<s>, A3<s>) of the acoustic source signal (A) was acquired, and transmits this in a respective radio signal (R1, R2, R3). A target device (T) receives the respective radio signals (R1, R2, R3), and based thereon produces a cancelling signal (CS<ST>) for an anti-noise signal (AN<ST>) that suppresses the acoustic source signal (AT) after having propagated from the noise pollution source (S) to the target device (T). The cancelling signal (CS<ST>) is produced based on the respective instances (A1<s>, A2<s>, A3<s>), the time-stamp data (t<1>, t<2>, t<3>), the information designating the respective positions (P1, P2, P3) of the devices and a target position (PT) of the target device (T).
