  1. 4159. Multi-GPU k-Wave for Large-Scale Ultrasound Simulation: A Comparison of Global and Local FFT Approaches (FA2026/157)

    k-Wave is widely used for time-domain ultrasound simulation, but large three-dimensional problems often exceed the memory and performance limits of a single GPU. Multi-GPU implementations are therefore required to enable larger computational domains while reducing simulation time.This work compares two multi-GPU implementations of the Fourier collocation scheme employed in k-Wave. The first...

  2. 4160. Benchmark Finite Element Model of a Building Acoustics Test Facility Based on DIN EN ISO 10140 (FA2026/104)

    A12 Numerical, Computational, and Theoretical Acoustics

    Within an acoustics-oriented design process, virtual prototypes play a crucial role in early design stages by enabling, for instance, the prediction of building acoustics. In this context, the sound transmission loss is an important quantity which can be measured in building acoustics test facilities according to DIN EN ISO 10140. This contribution presents a simple benchmark finite element...

  3. 4161. Time or frequency domain? Choosing modelling approaches for sound propagation from simple moving sources (FA2026/441)

    A12 Numerical, Computational, and Theoretical Acoustics

    When modelling sound radiation from moving sources such as passing trains or aircraft fly-overs, a key methodological choice is whether to work in the time or frequency domain. Although both approaches can be used to compute the received signal from monopole sources along arbitrary trajectories, their respective assumptions, computational costs, and suitability for different applications are...

  4. 4163. A new starting point for benchmarks in room acoustic simulations with CHORAS (FA2026/792)
    Maarten Hornikx (Eindhoven University of Technology)

    A12 Numerical, Computational, and Theoretical Acoustics

    There is a standing approach of benchmark studies and round robins in room acoustics modelling methods. These studies are typically carried out by participants who are also the developers of the software packages being evaluated. Although this approach is valuable, it leads to user bias and limits the reproducibility of the results. The rise of open-source software for room acoustics has...

  5. 4164. An extensible Benchmarking Framework for Computational Acoustics (FA2026/895)
    Ashwin Sadanand Nayak (Max Planck Institute Magdeburg)

    A12 Numerical, Computational, and Theoretical Acoustics

    Computational acoustics deals with a variety of data, mathematical models and numerical algorithms along with a disparate set of workflows to achieve insights into the physics of sound.The diversity of its approaches, while valuable, presents a significant challenge: a lack of systematic means to develop, compare, validate, and evaluate their performance against another under consistent...
