Session 1 – State of the Art and Trends in Transducer Simulation and Virtual Prototyping 

The use of simulation and modeling has always played a role in electroacoustics when designing transducers: from the first analytical models, lumped circuit equivalents, to the current powerful simulation software tools. Within the last years, the combination of increased computation power and innovation in the simulation tools has made full virtual development and testing possible. Modeling is used from the first conceptual phase to explore new and exotic design to the final high-fidelity virtual prototype.

In this presentation, you will learn about:

– The typical stages involved in modeling a new transducer through a series of examples.

– The latest trends and state of the art, for example, modeling of nonlinear effects.

– How classical lumped modeling approaches can still be integrated into modern tools.

– How simulation is being used to model transducers in their environment like a room or car cabin.

– How optimization is used to explore new designs 

Session 2 – Simulation of Sound Field Control Technologies in Automotive Listening Spaces 

Within the last decades, the emergence of simulation tools has provided new opportunities for advanced sound system development in the automotive domain. As opposed to concert halls and large room listening spaces, sound reproduction in car interiors introduces additional challenges and imposes significantly different constraints, that are nowadays addressed utilizing numerical mathematical modeling approaches. Along with experimental sandbox environments, simulation studies enable research and development engineers to comprehend the acoustical problems at a much higher level, and aids education and genuine knowledge creation across any technology company who rely on controlling and hence understanding specific physical metrics.

The presentation addresses the typical development-stages involved in pre-development of car-audio systems and is illustrated with examples of simulations studies utilized to characterize the sound field inside car interiors . 

Session 3 – From Crisp Packets to Cars; A Multiphysics Journey to Multiple Awards in the High-Fidelity Acoustic Space. 

Multiphysics simulations has played an integral role in the design, development and market launch of not one but two multi-award-winning headphone systems. This presentation explains how Xi Engineering assisted Warwick Acoustics launch and created a true listening experience. Initially targeting professional and home audio this journey has taken Warwick Acoustics into the automotive sector. The benefits of the system do not stop at unbelievable audio reproduction; the space and weight saving of electrostatics bring additional benefits.

In this presentation you will learn more about electrostatic speakers, structural-acoustic interaction modeling and – not least – two of the best headphones on the planet.
