摘　　要：随着计算机声学模拟技术的日渐成熟,声学模拟成为声学设计或声学改造项目中必不可少的一环。但是使用此类软件需要大量的工程经验积累与繁琐的匹配过程才能达到较为准确的结果。ODEON作为声学工程中广泛使用的声学软件之一,ODEON13版本中增加的基于遗传算法的材料优化工具--材料遗传优化器可以在一定程度上解决这个问题。文章首先介绍了材料遗传优化器的原理、计算过程和使用方法;基于实际教室改造案例,验证了该功能在声学模拟匹配和吸声材料修正的优越性与准确性;结果证明其对于材料的吸声系数可以进行一定的校准与修正,可为声学材料库的积累提供一定依据。With the maturity of computer acoustic simulation technology,acoustic simulation has become an indispensable part of acoustic design or acoustic transformation projects.However,the use of such software requires a large amount of engineering experience and a cumbersome matching process to achieve more accurate results.ODEON is one of the widely used acoustic software in acoustic engineering.The genetic material optimizer added in the ODEON13 version can solve this problem to some extent.The article first introduces the principle,calculation process and usage method of material genetic optimizer.Based on the actual classroom transformation case,the superiority and accuracy of the function in acoustic simulation matching and sound absorption material correction are verified.The results prove that the acoustic coefficient can be calibrated and corrected to provide a basis for the accumulation of the acoustic material library.
