Description
This book is the first of its kind. It provides the reader with a logical and highly quantitative means of including noise as a parameter
in the early design stages of a machine or structure. The unique and unified methodology builds upon the familiar disciplines of acoustics,
structural dynamics and optimization. It also exemplifies the art of simplification - the essence of all good engineering design. =
Strategies for designing quiet structures require extensive analytical and experimental tools. For computing the sound power from complex
structures the authors recommend a new 3-D, lumped parameter formulation. Not only this, they also include, on diskette, an original
numerical program POWER. This fully developed, user-friendly program can be applied generally to noise-control-by-design problems. Detailed
instructions for running the application are given in the appendix as well as several sample problems to help the user get started. =
The authors also describe a new instrument: a specially developed resistance probe used to measure a structure=92s acoustic surface
resistance. As an example, the procedure is outlined for measuring the valve cover of an internal combustion engine. Indeed, throughout
the book the reader is presented with actual experiments, numerical and physical that they can replicate in their own laboratory.
This
is a must-have book for engineers working in industries that include noise control in the design of a product. Its practical and didactic
approach also makes it ideally suited to graduate students.
Audience
First year graduate students in engineering and mechanical engineering; industrial engineers designing quiet machines in areas such as automotive, transport, aerospace, heavy machinery, and engines.
