Book Description
The fourth in a series of NASA/SAE Interior Noise Workshops was held on May 19 and 20, 1992 at the Graf Zeppelin Haus in Friedrichshafen, Germany. The theme of the workshop was new technology and applications for aircraft interior noise with emphasis on source noise prediction; cabin noise control, including active and passive methods; and cabin interior noise test procedures. This report is a compilation of the presentations made at the meeting which addressed the above issues.
Active Control Of Aircraft Cabin Noise
Author: Ignazio DiminoPublisher: World Scientific
ISBN: 1783266597
Category : Technology & Engineering
Languages : en
Pages : 303
Book Description
'The text is well written and supported by clear and useful illustrations. This would be a useful textbook for postgraduate or advanced undergraduate studies and would also make a good introductory text for engineers moving into the field. The literature survey and bibliography provide a useful starting point for further study.'The Aeronautical JournalActive Control of Aircraft Cabin Noise provides a bridge to fill the gap between robust control theory and practical applications of active noise control systems in aircraft cabin. Both the possibilities and limitations of structural solutions to enhance aircraft cabin comfort by reducing interior noise are discussed supported by a wide range of topics in engineering, from finite element modeling to multichannel adaptive feed-forward control, usually dealt separately in the literature. In addition, experimental noise attenuation results with passengers' subjective perceptions predicting the effects of cabin noise on comfort assessments is examined. Theoretical and experimental research is detailed enough to capture the interest of the non-expert in engineering who wishes to have an overview of some of the active noise control applications in aircraft. This book may be used as an advanced textbook by graduate and undergraduate students in aeronautical engineering, and would be an authoritative resource book for research into the subject.
Interior Noise Prediction Methodology

Book Description
The Acoustical Theory for Design of Aircraft Cabins (ATDAC) is a computer program developed to predict interior noise levels inside aircraft and to evaluate the effects of different aircraft configurations on the aircraft acoustical environment. The primary motivation for development of this program is the special interior noise problems associated with advanced turboprop (ATP) aircraft where there is a tonal, low frequency noise problem. Prediction of interior noise levels requires knowledge of the energy sources, the transmission paths, and the relationship between the energy variable and the sound pressure level. The energy sources include engine noise, both airborne and structure-borne; turbulent boundary layer noise; and interior noise sources such as air conditioner noise and auxiliary power unit noise. Since propeller and engine noise prediction programs are widely available, they are not included in ATDAC. Airborne engine noise from any prediction or measurement may be input to this program. This report describes the theory and equations implemented in the ATDAC program. Mathur, Gopal P. and Gardner, Bryce K. Unspecified Center NAS1-18037; RTOP 535-03-11-03...
