Ease
Predicts how a room will sound — and how loudspeakers will perform in it — before a single speaker is installed.
What it is
About Ease
EASE (by AFMG, Ahnert Feistel Media Group) is industry-standard software for modelling room acoustics and sound reinforcement system design, simulating how sound propagates, reflects and reverberates within a 3D room model. Acousticians and sound designers use it to predict speech intelligibility (STI), reverberation time and coverage uniformity for venues like theatres, stadiums, houses of worship and concert halls, and to optimise loudspeaker placement before installation. It integrates with manufacturer loudspeaker data (GLL files) so designs can be validated against real product performance.
What you can do with it
Capabilities
Build 3D acoustic models of rooms and venues
Simulate loudspeaker coverage, SPL distribution and speech intelligibility (STI)
Predict reverberation time and room acoustic parameters against relevant standards
Optimise sound system design before installation using real loudspeaker GLL data
Produce auralisations to let clients hear a simulated space
How to learn it
Learning Resources
AFMG's official EASE training courses and certification
AFMG's user manual and application notes (free with licence)
Acoustics-focused university and professional courses (e.g. Institute of Acoustics diploma modules)
Practise via AFMG's demo version on sample project files
Pro Tip
Always validate your simulated room's reverberation time against a real or comparable measured space before trusting predicted intelligibility figures — model calibration matters more than raw simulation resolution.
