摘要
EASE是当今世界最流行的计算机声学辅助设计软件,可预测声频系统的各种指标,但很多使用者在使用上对EASE的某些功能或概念不甚了解,并且对使用EASE的目的性不明确,认为使用EASE只是为了应付投标或客户的需要而已,忽略了EASE对实际的工程项目所具有的前瞻和指导意义。对使用EASE应注意的几个声学问题进行了阐述,例如常被人忽略的扬声器的各向相频数据对干涉的影响、如何获得更符合实际的混响时间数值等,并明确了EASE实用化的前提条件和指导意义。
Although EASE is the most popular software for acoustic design,which can be used to predict audio system' s performance,most people do not understand clearly some of the functions or concepts about EASE,and even some people think that EASE is just used to get some beautiful pictures that can be handed out to the clients,but ignore the significant purpose of EASE:direction for engineering.This paper presents some issues about the precision of different prediction in EASE,and how to use EASE to direct the engineering.
