Acoustic resonances are modified when objects are introduced into a chamber. The magnitude of these changes depends on the object position, size, and shape, as well as on its acoustic properties. Here, an experimental study ...

Noise in industrial workplaces has become an important occupational problem. Accordingly, there is a need to implement cost-effective strategies for reducing noise levels.In this paper, an optimal design methodology of ...
