Download or read book Active Control Of Aircraft Cabin Noise written by Ignazio Dimino and published by World Scientific. This book was released on 2015-07-13 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: '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.

Book excerpt: All persons associated with the operation of military aircraft are exposed at one time or another to hazardous noise. In past years attention was directed only to the noise problems encountered by aircrew members, namely, possible noise-induced hearing loss, excessive fatigue, and difficulty of voice communication. Air-Force-wide adoption of the turbojet-powered aircraft has prompted the giving of special attention to the hazardous noise environment of men working on and near aircraft on the ground. While aircrew members of some aircraft are exposed to high-intensity noise levels, the aircraft ground maintenance crews receive most of the hazardous noise exposures.

Download or read book Noise Environs and Helmet Performance for the P-1127 V/STOL Aircraft written by Henry C Sommer and published by . This book was released on 1968 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the evaluation was (1) to measure the acoustic noise environment in the cockpit of the United Kingdom Hawker Siddeley P-1127 V/STOL aircraft that would serve as an acoustic guideline for cockpit noise levels of aircraft being contemplated or under construction, and (2) to determine the acoustic attenuation of various Air Force flight helmets in the inventory or being contemplated for Air Force inventory items. Cockpit sound pressure levels in the P-1127 V/STOL aircraft at various engine rpm settings were measured. The cockpit noise environment at maximum engine rpm was reproduced in the laboratory and used to obtain objective attenuation data for three Air Force flight helmet/liner configurations. Measurement of real-ear attenuation at threshold were also accomplished on the helmet/liner configurations. (Author).

Download or read book Comparison of Speech Intelligibility in Cockpit Noise Using Sph-4 Flight Helmet with and Without Active Noise Reduction written by National Aeronautics and Space Adm Nasa and published by Independently Published. This book was released on 2018-11 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: Active Noise Reduction (ANR) is a new technology which can reduce the level of aircraft cockpit noise that reaches the pilot's ear while simultaneously improving the signal to noise ratio for voice communications and other information bearing sound signals in the cockpit. A miniature, ear-cup mounted ANR system was tested to determine whether speech intelligibility is better for helicopter pilots using ANR compared to a control condition of ANR turned off. Two signal to noise ratios (S/N), representative of actual cockpit conditions, were used for the ratio of the speech to cockpit noise sound pressure levels. Speech intelligibility was significantly better with ANR compared to no ANR for both S/N conditions. Variability of speech intelligibility among pilots was also significantly less with ANR. When the stock helmet was used with ANR turned off, the average PB Word speech intelligibility score was below the Normally Acceptable level. In comparison, it was above that level with ANR on in both S/N levels. Chan, Jeffrey W. and Simpson, Carol A. Unspecified Center NAS2-12425; NAS2-13188; RTOP 505-61-51...
