Abstract (en)
[origin: WO2008053435A1] An acoustic cooling system comprising a first transducer (3) adapted for cooling by generating sound waves, a second transducer (4) adapted for cooling by generating sound waves, and a signal-processing unit (6) adapted to generate a cancellation signal for noise generated by the acoustic cooling system. The second transducer (4) is adapted to convert the cancellation signal into sound which at least partly cancels the noise.
