The ESDU Aircraft Noise Series provides a range of methods for predicting aircraft noise levels. ESDU 09009 provides an overview of the extent to which currently-available prediction methods can meet the particular circumstances for which the user may desire to perform a...
This Aerospace Recommended Practice (ARP) provides two methods for measuring the aircraft noise level reduction of building façades. Airports and their consultants can use either of the methods presented in this ARP to determine the eligibility of structures exposed to aircraft...
PREFACE TO AIRCRAFT NOISE SERIES Noise, from whatever source, has become a matter of wide concern. Those responsible for the design, certification and operation of aircraft of many different types need to apply their skills more and more to minimizing the health hazards,...
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....
ESDU 02020 is an overview of the various sources of noise from aeroplanes and helicopters and includes consideration of the propagation of that noise outside and inside the vehicle together with the various influences that may modify the noise before its perception by an...
The scope of this ARP embraces the description of a configuration for a ground-plane microphone installation that may be used to determine sound pressure levels equivalent to those which would have been measured in an acoustic freefield at the microphone location. The one-third - octave-band...
ESDU 81035 gives guidance on the estimation of lateral attenuation of aircraft noise from noise measurements. Lateral attenuation is defined as the difference between the under-the-flightpath
This document specifies requirements for the electroacoustical performance of systems of instruments used to measure sound for the purposes of aircraft noise certification, and for other comparisons among aircraft models, and provides methods by which tests can be made...
Defines a weighting characteristic, designated D, for certain measurements of aircraft noise.
