Vibrações e Acústica
Objective
Noises have been a constant concern in industrial, commercial and residential environments. Standards and ordinances have been limiting admissible noise levels in different situations, imposing the study of solutions at the source, the path or the receiver.
On the other side, the conditions of operation of rotating machines can be characterized for the pattern of vibrations emitted by them, which can be measured in one of its external surfaces, giving a diagnosis of the operating conditions without the need to stop the machine.
The characterization of attenuating materials, the development of dynamic methods of vibration neutralization, the identification of noise and vibration sources, and the study of propagation modes are some of the research interests in this area of concentration.
