Résumé

In many industrial applications, and especially in transport industry, sound perception is an important aspect manufacturers have to consider during the development phase of their products. At this step, numerical models are often used to solve the partial differential equations governing the problem. On one hand, a disadvantage of such numerical methods is the high computational cost to pay when a fine representation of the physics is necessary. On the other hand, the human hearing system has some limitations and cannot perceive all the details of the physical sound. It appears therefore reasonable to reduce the accuracy of simulations, though maintaining them "fine enough" to ensure that computed sounds can be used in sound quality experiments. This paper investigates the effect of several numerical parameters on the perception of sounds obtained by convolving a simulated transfer path (TP) with a recorded sound signal. The transfer path is simulated via a Finite Element (FE) model validated with a physical mockup and taken as reference. Then, the same transfer path is simulated using less accurate Finite Element models and a sensitivity analysis checks how those changes affect psychoacoustic metrics associated to sound quality. Finally, hearing tests are conducted to determine the effect of calculation parameters on the perceived similarity between sounds.
