Auralization of a Tuning Fork

Through the auralization it is possible to simulate in advance the acoustics of a prototype under development. The simulation of the sound of a product before its construction allows the optimization of time and costs, as it would allow the production of only the best design variant or would reduce the phase of post-processing optimization [1]. The aim of this study is to simulate the sound of a numerical model and to obtain an audio file as little artificial as possible and with no artifacts. In order to achieve this goal, a number of studies [1, 2, 3, 4, 5, 6] have been recognized that follow the scheme represented in the Figure 1. Therefore this procedure will be performed in this analysis.

A study of this type requires the modeling of the dynamic forces acting on the system and a numerical model that reproduces its dynamic vibrational behavior and the consequent acoustic radiation of the excited modes through a coupled FEM-BEM simulation. The results obtained from the BEM simulation already represent an auralization in free field and the audio results obtained in free field will be compared.
