Computer simulation of acoustics is an essential technology that underpins many of our other research prioritise e.g. to enable virtual optimisation of designs or to train AI systems. But current methods are not sufficient and the frontiers need to be pushed through research in this field too. Bigger problems may require exascale computing or new mathematical approaches. More autonomous solutions in acoustics might require new intelligent computational and data analysis algorithms coded to automatically adapt to different special effects, environmental change and mathematical instabilities. Key applications include virtual acoustic prototypes, digital twinning and machine learning for simulating the noise and vibration impact from machines, structures and devices.
