Download or read book Method to Calculate Behind Start of Takeoff Roll Noise Level Adjustments written by A-21 Aircraft Noise Measurement Aviation Emission Modeling and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes a method to calculate noise level adjustments at locations behind an airplane (described by an angular offset or directivity) at the start of takeoff roll (SOTR). This method is derived from empirical data from jet aircraft (circa 2004), most of which are configured with wing-mounted engines with high by-pass ratios (Lau, et al., 2012). Methods are also described which apply to modern turboprop aricraft.Calculations of other propagation-related adjustments required for aircraft noise prediction models are described in AIR1845A, ARP5534, ARP866A, and AIR5662. This AIR describes a method to calculate noise level adjustments at locations behind an airplane at the start of takeoff roll (SOTR) for the purposes of aircraft noise prediction modeling. This method replaces the methods found in paragraph 3.3.1 (Sound Exposure Level Behind the Start-of-Takeoff Roll) of AIR1845A "Procedure for the Calculation of Airplane Noise in the Vicinity of Airports". Specifically, the calculations presented in 3.1 and 3.2 of this document replace the calculations in Step 3 of paragraph 3.3.1 of AIR1845A. It adheres to the basic approach described in AIR1845A and is based on measurements from modern jet and turboprop aircraft (circa 2004). The behind start of takeoff roll noise directivity method found in AIR1845A is based on measurements of older-generation (circa 1980), low by-pass ratio aircraft, primarily configured with fuselage-mounted engines. The new method described herein for modeling the noise directivity behind start of takeoff roll is derived from empirical data from modern jet aircraft, most of which are configured with wing-mounted engines that tend to have higher by-pass ratios as well as operate at higher thrust levels. Additionally, this AIR version includes a separate directivity adjustment for propeller-driven aircraft. Comparison of directivity adjustments computed from the method described herein and the AIR1845A method are presented in Appendix A. AIR6297 has been reaffirmed to comply with the SAE Five-Year Review policy.

Download or read book Aviation Noise Impact Management written by Laurent Leylekian and published by Springer. This book was released on 2022-03-15 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book provides a view into the state-of-the-art research on aviation noise and related annoyance. The book will primarily focus on the achievements of the ANIMA project (Aviation Noise Impact Management through Novel Approaches), but not exclusively. The content has a broader theme in order to encompass. regulation issues, the ICAO (International Civil Aviation Organization) balanced approach, progresses made on technologies and reduction of noise at source, impact of possible future civil supersonic aircraft, land-use planning issues, as well as the core topics of the ANIMA project, i.e. impact on human beings, annoyance, quality of life, health and findings of the project in this respect. This book differs from traditional research programmes on aviation noise as the authors endeavour, not to lower noise at source, but to reduce the annoyance. This book examines these non-acoustic factors in an effort to help those most affected by aviation noise – communities living close to airports, and also help airport managers, policy-makers, local authorities and researchers to deal with this issue holistically. The book concludes with some recommendations for EU, national and local policy-makers, airport and aviation authorities, and more broadly a scientifically literate audience. These recommendations may help to identify gaps for progress in terms of research but also genuine implementation actions for political and regulatory authorities.

Book excerpt: Aircraft noise has adverse impacts on passengers, airport staff and people living near airports, it thus limits the capacity of regional and international airports throughout the world. Reducing perceived noise of aircraft involves reduction of noise at source, along the propagation path and at the receiver. Effective noise control demands highly skilled and knowledgeable engineers. This book is for them. It shows you how accurate and reliable information about aircraft noise levels can be gained by calculations using appropriate generation and propagation models, or by measurements with effective monitoring systems. It also explains how to allow for atmospheric conditions, natural and artificial topography as well as detailing necessary measurement techniques.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes methods for calculating the attenuation of sound due to line-of-sight blockage or shielding from non-level terrain. This method applies to sound propagating from an airplane to locations on the ground during ground roll, climbout after liftoff, and landing operations.AIR1845 and AIR5662 provides guidance for modeling aircraft noise at airports with flat terrain. In reality, many airports are surrounded by non-level terrain that may result in attenuation (or shielding) of sound at some receptors. This noise blockage can be accounted for with the line-of-sight blockage calculation, based on the difference in propagation path length between the direct path and propagation path over the top of terrain feature. The purpose of this aircraft information report is to provide a method that accounts for the attenuation due to line-of-sight blockage of aircraft noise by terrain features. This Aerospace Information Report (AIR) describes a method to calculate noise level adjustments due to line-of-sight blockage (LOS) of the noise propagation between a source and receiver by terrain for the purposes of aircraft noise prediction modeling.AIR1845 provides guidance for modeling aircraft noise at airports with flat terrain. In reality, many airports are surrounded by non-level terrain that may result in noise blockage (or shielding) at some nearby receptors. This noise blockage can be accounted for with the line-of-sight blockage calculation, based on the difference in propagation path length between the direct path (straight line between source and receiver, terrain feature absent) and the propagation path over or around the terrain feature.
