Measurements for Loudspeaker Modeling Files

Loudspeaker modeling files are most often used with acoustical modeling programs such as EASE, Focus, CATT-Acoustic, and others to help determine how well the loudspeakers cover the audience areas and how much “spill” there is on the room’s surfaces. It is important to have accurate data about the characteristics of the loudspeakers that are used in the models. In this article, we will detail some of the requirements to help assure good measurement data for use with loudspeaker modeling. This article was originally published in Voice Coil, April 2017.

Advanced Engineering Simulation Software

Simulation software for speaker design has been around since the 1970s. With the introduction of the IBM PC and DOS operating system in the early 1980s, Thiele-Small (T-S) simulation software for enclosure design became a must-have for speaker system designers. For the most sophisticated design efforts, there are now magnetic circuit design software and finite element analysis (FEA) cone and thermal prediction simulation software.
