SUMMARY:Simulating Biological and Engineered In-Air Acoustic Systems Using
  Ray Tracing
DESCRIPTION:Wouter Jansen (University of Antwerp)\n\nRay tracing offers po
 werful capabilities for simulating wave propagation in diverse scientific 
 fields, including acoustics. This presentation focuses on its application 
 to in-air acoustic simulations, furthering our understanding of biological
  echolocation (e.g., bats) and advancing the development of in-air 3D sona
 r arrays, associated signal processing, and robotic applications. Our work
  in this area has evolved over time, initially using simpler 2D intersecti
 on calculations and progressing towards ray tracing methods capable of han
 dling 3D scenes. Simulating the complex pulse-echo interactions of sound w
 aves within detailed dynamic environments, involving multiple bounces and 
 material-dependent reflections, presents significant computational challen
 ges for which we will discuss our transition towards using hardware-accele
 rated ray tracing GPUs. This direction provides the ability to simulate la
 rger, more complex scenes with moving objects and unique acoustic surface 
 properties. We will discuss how key domain-specific challenges are tackled
 , such as modeling diffraction, alongside the continued need to optimize r
 ay traversal and reflection calculations for achieving desired simulation 
 fidelity efficiently on parallel hardware. This simulation framework facil
 itates rapid prototyping and testing of bio-inspired sonar sensors and the
 ir applications, enhances our understanding of complex animal behaviors, a
 nd provides a valuable tool bridging computational physics, robotics, and 
 bioacoustics.\n\nDomain: Engineering, Life Sciences, Physics\n\nSession Ch
