Development of Tensional Acoustic Signal Measurement System for Fatigued Bill Classification

Abstract

We have developed new emission methods of tensional acoustic signal of bill, specialized for embedded-type fatigued bill classification system. We have constructed a model mechanism that emulates of the transportation part of practical banking machines, for emitting tensional acoustic signal of bill. Two acoustic energy based feature values are introduced for evaluation of proposed emission methods of tensional acoustic signal. Experimental results show the effectiveness of the proposed methods.
