SOUND ANALYZER BASED ON A BIOMORPHIC DESIGN

摘要

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 (20Oa' ..., 200c; 200a', ..., 200c') providing high-frequency attenuation.
