Acoustic Simulation: EASE 5’s Acousteer Engine Redefines Design Workflows

Acoustic simulation has long been a cornerstone for audio professionals, yet the iterative process of design, calculation, and analysis has traditionally been hampered by significant computation times and laborious workflows. AFMG's new Acousteer engine introduces a paradigm shift, transforming direct sound field simulation into an interactive, real-time experience.

The August 2025 issue offers a Market Update on New Dimensions in Acoustics, and expands the topic with articles by Daniel Gert Nielsen (Treble), Stefan Feistel and Wolfgang Ahnert (AFMG), and Neil Shaw (Menlo Scientific Acoustics). Richard Honeycutt’s column addresses the Acoustical Effects of Floor Finishes, and Dimitri Danyuk reviews Ethan Winer’s The Audio Circuits Cookbook. Philipp P. Klose reviews the Neumann Reference Immersive Monitoring Environment (RIME) solution, and René Christensen offers a Microacoustics Modeling Primer on Numerical Modeling.

Harro Heinz, the co-founder of Renkus-Heinz, celebrated a major milestone on December 14: his 90th birthday – an event that sits synchronously within the 40th year of the company that bears his name. For 40 years, Harro has fearlessly led Renkus-Heinz through technology evolutions, innovations and advancements, and he's kept his company close, and his family even closer. And important to note: the celebration is not a retirement.

From March to August 2014, in its Sound Control column dedicated to acoustics, Richard Honeycutt reviewed and wrote a series of articles on the evolution of predictive acoustics and acoustical modeling software, including a review of some of the available tools. This fourth article in the series discusses Enhanced Acoustic Simulator for Engineers (EASE), an engineering design and analysis software for optimizing acoustics. This article was originally published in audioXpress, June 2014.

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.
