Available in PDF, EPUB and Kindle. Book excerpt: For various aircraft flyovers, speech intelligibility scores and calculations of AI (Articulation Index) were obtained as functions of time. These data were then used to establish the relation between AI and intelligibility for time-varying noise. A similar relation was also obtained for steady-state simulated jet noise. A comparison of the two relations showed that for a given AI, the time-varying noise provided less masking than the steady-state noise. The difference found between the two relations cautions against the use of relations established for steady-state noise to predict intelligibility scores that might be obtained with time-varying noise. The aircraft flyovers employed in the intelligibility tests were also presented to listeners who were asked to rate them in terms of their acceptability in the home. Using a rating scale having the categories 'of no concern, ' 'acceptable, ' 'barely acceptable, ' and 'unacceptable, ' judgments were obtained in three listening situations: (1) in the presence of radio-TV speech; (2) in the absence of speech; and (3) in the presence of telephone speech.

Download or read book A Guide To U S Aircraft Noise Regulatory Policy written by Sanford Fidell and published by Springer Nature. This book was released on 2020-07-03 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aviation noise remains the primary hindrance to expansion of airport and airspace capacity in the United States. This book describes the development and practice of U.S. aircraft noise regulation, as well as the practical consequences of regulatory policy. Starting in the pre-jet transport era, the book traces the development of the modern framework for characterizing, standardizing, predicting, disclosing, and mitigating aircraft noise and its effects on airport-vicinity communities. Among other matters, the book treats noise-related consequences of the 1978 deregulation of the airline industry; prediction and mitigation of community reaction to airport noise; land use compatibility planning; recent research and industry trends; and some suggestions for potential improvements to current policy. Initial chapters describe the assumptions underlying aircraft noise regulation, and lay out the chronology of U.S. aircraft noise regulatory practice. Later chapters provide overviews of population-level effects of aviation noise, including health effects, speech and sleep interference, and annoyance. Readers will learn why predictions of the prevalence of aircraft noise-induced annoyance have systematically underestimated adverse community response to aircraft noise, and how such underestimation has complicated approval and funding of airport and airspace improvement projects. They will also learn why attempts at noise-compatible land use planning are seldom fully successful.

This book was released on 1978 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recordings of the aircraft ambiance from ten different types of aircraft were used in conjunction with four distinct speech interference tests as stimuli to determine the effects of interior aircraft background levels and speech intelligibility on perceived annoyance in 36 subjects. Both speech intelligibility and background level significantly affected judged annoyance. However, the interaction between the two variables showed that above an 85 db background level the speech intelligibility results had a minimal effect on annoyance ratings. Below this level, people rated the background as less annoying if there was adequate speech intelligibility.

Book excerpt: Information is presented on 22 noise metrics that are associated with the measurement and prediction of the effects of aircraft noise. Some of the instantaneous frequency weighted sound level measures, such as A-weighted sound level, are used to provide multiple assessment of the aircraft noise level. Other multiple event metrics, such as day-night average sound level, were designed to relate sound levels measured over a period of time to subjective responses in an effort to determine compatible land uses and aid in community planning. The various measures are divided into: (1) instantaneous sound level metrics; (2) duration corrected single event metrics; (3) multiple event metrics; and (4) speech communication metrics. The scope of each measure is examined in terms of its: definition, purpose, background, relationship to other measures, calculation method, example, equipment, references, and standards.
