Acoustic simulations


Acoustic simulations arise more interest each day in the industry. The acoustics standards have become more strict as they now impose the study of the structure's vibro-acoustic behavior and noise transmission modes (structure-borne / radio) from the in the early development phases. Acoustic simulations are now just as unavoidable as the study of a structure's mechanical behavior.

Their aim is to determine the level of noise in a defined (confined or not) space for a given noise source.

Many numerical solutions exist, whether it is the prediction of an acoustic pressure level, the estimate of noise radiation outwards, the determination of sound pathways or the calculation of acoustic insulation performance.

Thanks to the evolution of computational power and numerical methods, acoustic finite element simulations have become viable over a wide spectral band, addressing issues in low and high frequencies.
