EASE 5 Third Edition Redefines Sound Reinforcement Planning with Acousteer Real-Time Simulation Engine

Discreetly introduced at the end of 2024 by Berlin-based AFMG Technologies, the Third Edition of EASE 5 updates this universal planning tool for loudspeaker systems with a real-time simulation engine called Acousteer. The new processing architecture allows users to calculate audience area mappings in milliseconds, with real-time adjustments, shifting the process from iterative to a dynamic exploration. The EASE 5 Third Edition suite not only empowers users to design sound systems with unprecedented accuracy, but also introduces the possibility to calibrate models accurately and collaborate live with other users and stakeholders.

Simulation Techniques: Perturbation Methods in Audio Engineering

Standard simulations are closely tied to the analytical framework much more than the numerical. Simulation software gives insight into physical products that could not be achieved otherwise, often leading to less attention being paid to analytical methods and descriptive mathematical expressions related to the physical application. This article explores an analytical approximation method described as a perturbation approach.

Development & Design: Experimental and Theoretical Investigation of an Unusually Shaped Horn

In another example of cutting-edge experiments that deserve recognition, Joerg Panzer (R&D TEAM, Germany) and Patrick Macey (PACSYS, UK) detail an investigation of the sound pressure response and radiation impedance of a loudspeaker horn driven by an electro-dynamic transducer. The two authors (and creators of the respective software tools) combined measurements with simulation software using finite and boundary element methods and explored the associated issues with meshing for each method.

Speaker Builder: Open-Baffle Subwoofer Simulation with Akabak

Speaker Builder: Open-Baffle Subwoofer Simulation with Akabak

Confronted with the impossibility to conduct reliable measurements in the low-frequency domain for his DIY speaker project, George Ntanavaras explores the alternative of relying solely on simulation software. To validate the design of an open-baffle subwoofer using the AKABAK software, created by German company R&D Team, he also explores the transition from measurements to simulation. His experiments contrast the near-field response measurements of his loudspeaker with the accuracy of the simulation using AKABAK.

Design, Simulations, and Measurements in Voice Coil December 2024
