The latest version of EASE 5 system modeling software from AFMG Technologies sees the inclusion of HOLOPLOT X1 and X2 products, facilitating the ability of users to model Matrix Arrays and Beam Optimizations to view sound pressure level simulations, with the resulting array configurations exported to EASE 5 for further analysis based on closed-room simulation.
“The changes required to accommodate the complexity of HOLOPLOT X1 and X2 data will benefit all end users of EASE 5, with the enhanced support for cluster-type GLL files recently released in EASE 5.59 and the improved data flow between HOLOPLOT Plan software and EASE 5,” states AFMG managing director Stefan Feistel.
The addition of the room simulations with EASE 5 enables all closed-room performance metrics such as diffuse fields, STI and auralization predictions to be obtained and compared with any product from the 150 brands contained in the EASE 5 Library. Objective validation can be another benefit of using a brand-independent software to model loudspeaker systems and room acoustics.
Emad El-Saghir, fellow at HOLOPLOT, has real world experience with using EASE, explaining, “We were early adopters of the EASE software. Before the new EASE 5 updates we had a hard time simulating large projects such as Sphere because of the huge arrays and large numbers of inputs involved. AFMG were very supportive, providing us with a dedicated server to run our calculations and simulations.
“By 2018/2019, we had a special version of EASE to run our simulations, so we could stop using the dedicated server,” he continues. “In the early planning stages of Sphere, I could actually design the layout of the system and size the arrays. At the time, the development of our own tools to design was work in progress, so this allowed us to work on the Sphere. Today, our own tools are much more powerful, but back then these more simple tools were extremely helpful.”
The new performance requirement for HOLOPLOT simulations in the design of Sphere can provide benefits to other users. A 64-bit version of the calculation engine utilized by HOLOPLOT, as well as other advancements, are now available to all regardless of their loudspeaker choices.
“You can now open a project in EASE and simply scroll down to HOLOPLOT in the loudspeaker library,” Feistel says. “This allows you to experience accurate calculations for the Matrix Array inside that venue and is a very interesting scenario for users to explore.”
“Beyond Sphere, EASE was utilized on other major HOLOPLOT projects,” El-Saghir concludes. “That’s the power of the GLL format and the accessibility of combining HOLOPLOT Plan with EASE. The comparisons between simulation results and real-world experience are very pleasing and have been repeatedly confirmed in even the most difficult venues to achieve good agreement.
“EASE must be the choice of any consultant that wants to use HOLOPLOT Matrix Arrays. It is the power and accuracy of AFMG’s award-winning modeling engine that makes it the best possible solution for a meaningful simulation of our systems.”
