Acoustic design for noise reduction

J. Nicolas, N. Atalla, A. Berry, J.-B. Plaud

Abstract


Control by an appropriate structural acoustics and vibration design which consist essentially in modifying mechanical parameters of the structure: change the dimensions, the material characteristics, add stiffeners, add local masses, add damping internally and externally, or modify the fixations conditions, decrease the energy transmission between coupled structures or systems
