介绍计算机声学设计软件 – EASE

    EASE was first introduced to the professional audio industry in 1990 at the 88th AES Convention, now it becomes one of the most famous acoustic design softwares widely used by the sound system designers and electro-acoustic engineers in the world. We see the evolution history of EASE from the MS-DOS version – EASE2.1, released in 1994, then EASE3.0, the first version of EASE to run in window with EARS module integrated, then EASE 4.0 with AURA and IR INFRARED modules integrated, to EASE 4.2 of today, which has more user-friendly room modeling construction tools and more powerful mathematical and acoustical algorithms, AFMG will officially release EASE4.3 very soon. The value of EASE is to provide accurate acoustic predictions in order to eliminate costly mistakes and reduce installation time. Through the graphical interfaces, EASE presents a wide range of scientifically calculated acoustic simulations such as Direct SPL, Total SPL, Critical Distance, D/R Ratio, Arrival Time, ITD Gap, Lspk Overlap, C Measurements, ALCONS, RASTI. AURA (Analysis Utility for Room Acoustics) allows the calculations of all key room acoustical parameters defined in ISO3382, these include EDT, T10/20/30, LF/LFC, C50/80, Sound Strength, Center Time, Direct SPL, Total SPL, Echo Criteria for Speech and Music, STI and AlCons. AURA's calculations are based on ray tracing, not with Eyring or Sabine formula anymore.

　　自1990年第88次AES大会被初次介绍给专业电声及音响界以来，EASE软件已经发展成为今天世界最知名专业声学设计软件之一，被声学工程师在世界范围内广泛应用于声学设计。EASE软件的发展历程经过了1994年DOS版的EASE2.1，1999年WINDOW版的EASE3.0并入了试听模块（EARS）, 2002年EASE4.0并入了室内声学分析模块（AURA）和用于设计会议厅的红外辐射模块（IR INFRARED），至2007年升级为EASE4.2版本，使建模更简便，计算结果更准确，运算速度更快速，截止到笔者写此文章，德国AFMG公司即将正式推出EASE4.3，此版本使建模功能更强大，并且进一步完善了EASE程序操作。
