Book Description
This report summarizes the work conducted by the Structural Acoustics Integrated Technology Development (ITD) Team under NASA's High Speed Research (HSR) Phase II program from 1993 to 1999. It is intended to serve as a reference for future researchers by documenting the results of the interior noise and sonic fatigue technology development activities conducted during this period. For interior noise, these activities included excitation modeling, structural acoustic response modeling, development of passive treatments and active controls, and prediction of interior noise. For sonic fatigue, these activities included loads prediction, materials characterization, sonic fatigue code development, development of response reduction techniques, and generation of sonic fatigue design requirements. Also included are lessons learned and recommendations for future work.

Book Description
The book describes analytical methods (based primarily on classical modal synthesis), the Finite Element Method (FEM), Boundary Element Method (BEM), Statistical Energy Analysis (SEA), Energy Finite Element Analysis (EFEA), Hybrid Methods (FEM-SEA and Transfer Path Analysis), and Wave-Based Methods. The book also includes procedures for designing noise and vibration control treatments, optimizing structures for reduced vibration and noise, and estimating the uncertainties in analysis results. Written by several well-known authors, each chapter includes theoretical formulations, along with practical applications to actual structural-acoustic systems. Readers will learn how to use vibroacoustic analysis methods in product design and development; how to perform transient, frequency (deterministic and random), and statistical vibroacoustic analyses; and how to choose appropriate structural and acoustic computational methods for their applications. The book can be used as a general reference for practicing engineers, or as a text for a technical short course or graduate course.

Book Description
Over the last thirty years the European aeronautical industry has achieved a respected and internationally successful position. This EC-Aeronautics Research Series provides the opportunity to present the results of recent research projects in areas critical to the future competitiveness of the industry in world markets. It contains Technical Publications of the completed EC-Aeronautics pilot phase project work, which has been supported under Area 5 : "Specific Activities Relating to Aeronautics" of the Brite/Euram Programme within the Second Framework Programme of European Community Activities in the Field of Research and Technology Development (1989?1992). This volume presents the three projects which, under this pilot phase, carried out work in three areas of noise and acoustics technologies: exterior noise, cabin noise, and acoustics loads in relation to structural fatigue.

Book Description
Architectural Press Library of Design and Detailing: Acoustic Design focuses on the techniques and principles employed in acoustic design, as well as room acoustics, hearing, speech, sound insulation, and noise control and design. The book first elaborates on the perception of sound, properties of sound, and sound in the built form. Concerns cover sound absorption, room acoustics, sound insulation, physical data, units and measurement, sound at a point, and hearing and speech. The manuscript then takes a look at noise control and design. Topics include prediction and prescription, control at source, control in the sound path, building types, and building elements. The text is a valuable source of information for researchers interested in acoustic design.

Book Description
The third edition of Engineering Noise Control has been thoroughly revised, updated and extended. Each chapter contains new material, much of which is not available elsewhere. The result is a comprehensive discussion of the theoretical principles and concepts of acoustics and noise control, a detailed discussion of the hearing mechanism, noise measuring instrumentation and techniques, noise criteria, sound source characterization and emission, outdoor sound propagation, sound in rooms, sound transmission through partitions, enclosure design, dissipative and reactive mufflers, vibration isolation, equipment sound power emission calculations and active noise cancellation. The book is an excellent text for advanced undergraduate or graduate students of acoustic and noise control, and it also contains essential information and prediction techniques that make it an invaluable resource for the practitioner.

Book Description
Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air. The author’s tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension. Fundamental chapters on the physics and perception of sound precede those on noise reduction (elastic isolation) methods. The last chapter deals with microphones and loudspeakers. Moeser includes major discoveries by Lothar Cremer, including the optimum impedance for mufflers and the coincidence effect behind structural acoustic transmission. The appendix gives a short introduction on the use of complex amplitudes in acoustics.
