Events

Founded in 2007, ISEAT is a high-level international exchange platform for electroacoustic technology. Having been successfully held multiple times, it has won a worldwide reputation in the field of electroacoustics and related areas.

At ISEAT, attendees can experience the latest advancements in sound technology, gain in-depth insights into the forefront of electroacoustic developments, and receive professional feedback through interactive discussions. ISEAT also acts as a platform for interdisciplinary communication, where ideas from various fields intersect to inspire new creativity.

The symposium is organized by the Shenzhen Research Institute of Nanjing University. The official languages are Chinese and English. ISEAT 2025 will take place from 8th of November to 9th of November. 

We are pleased to announce the presentation of our paper, “Interactive Sound System Design Using Real-Time Acoustic Simulation,” at ISEAT 2025.

The presentation, presented by Stefan Fistel via video format, will feature English audio with Chinese subtitles. The paper introduces a novel approach to designing interactive sound systems through the application of real-time acoustic simulation. A preview of the work is provided in the abstract below:

Abstract

Professional sound system design is typically supported by acoustic simulations. These simulations are essential to analyze and address the complex challenges related to achieving SPL uniformity and maximizing sound system output in a given venue. Also, the planning of delay systems, beam-steering applications, or selecting suitable loudspeakers are often important aspects that require acoustic modeling. However, acoustic simulations have been known to be notoriously time-consuming and tedious to run. Given this context, we showed in a recent article that the latest advancements in CPU and GPU technology in combination with a new, purpose-built software architecture make it possible to conduct high-resolution acoustic simulations in real time. Building on that, the paper presented here puts a focus on how the design process is affected by the interactivity of the software and the live updates of calculation results. This includes in particular the optimization of the sound system coverage and its uniformity using heat maps and distribution statistics as well as the design of delay systems using precedence principles when localization requirements are given. It is discussed how the real-time ability of the simulation engine is changing design workflows for each acoustic metric and its corresponding control parameters. As the simulation system now provides an instantresponse feedback loop, learning cause-and-effect relationships, experimenting with design ideas, and collaborating on concepts is made much easier. Secondly, the discussion of the research work also comprises technical details of the proposed implementation and architecture. Performance comparisons with conventional software solutions are presented. Additionally, numerical analysis results are provided for the nonlinear scaling of the implementation on modern computer hardware with respect to the number of data points. Suitable PC hardware is discussed and recommendations are given for practitioners.

We will be represented during the conference by Johnson Chow of Initial Audio Concept (IAC), who will serve as our primary contact person.
