| Abstract: | A three layer feedforward neural network is developed for sound recognition which is made up by four kinds of sound in this paper.Based on the steepest descent method,the BP network is trained by an improved learning algorithm in which momentum factor and learning rate adjustment is adopted.The simulation results indicates that the error in classification small also with high recognition correct in terms of a percentage. |
