One of the most important tasks in engineering is to reduce the noise caused by vibrating bodies for designing competing products capable of meeting costumer demands and legitimate regulations. The designer should investigate the optimum design parameters without reducing the operation performance. Design sensitivity analysis is the first and the most important step in the optimization process, because it yields the information about the increment or the decrement tendency of the design objective function with respect to the design parameter. Therefore, acoustic sensitivity analysis plays an...

In the high frequency analysis of vibrating systems, averaged energies are of interest to describe the response level. However, energetic parameters do not include modal information and thus exhibit smooth characteristics. In this book, the development of an efficient tool considering primary response variables in a discrete manner is mainly proposed. In this regard, two approaches are developed based on Discrete Singular Convolution. The accuracy of these approaches is validated by comparing with available analytical solutions. As a secondary study, this book introduces two different...
