A device and a method for analyzing sound based on a biomorphic design are disclosed. The device comprises a plurality of amplification/filtering stages (S1, . . . , Sn) connected in a series configuration. Each amplification/filtering stage comprises at least one nonlinear amplification module (100a, . . . , 100c), preferably a Hopf amplifier, and at least one filter module (200a′ . . . , 200c; 200a′, . . . 200c′) providing high-frequency attenuation.
