An automatic design method of compact acoustic systems by the genetic algorithm

摘要

In this paper, we propose a design method of compact acoustic systems for preventing the sensitivity decline due to leaks by the Genetic Algorithm. This method can design acoustic equivalent Circuits and the corresponding acoustic parameter values whose Sound Pressure Level is within the range based on the GSM(ETSI EN 300 903) and prevent the sensitivity decline. The proposed method uses the PfGA (Parameter-free Genetic Algorithm) for the design of equivalent circuits and the Michalewicz's Genetic Program for the design of acoustic parameters. We can obtain some equivalent circuits whose frequency response is hardly affected by leak. This method can be used for compact acoustic systems such as cellular phones. Furthermore, you can obtain useful information from the design results.
