User's Manual for Automated Calculation of Fleet Noise Level and Airport Noise Index

摘要

This manual provides instructions to the users of a series of programs that calculate fleet noise level (FNL) and airport noise index (ANI). The concept of FNL provides a method for evaluating the noise status of fleets of aircraft. Using FNL, comparisons can be developed between fleets for all airports or subsets of airports. It is an average of acoustical energies. The ANI is a measure that is sensitive to total acoustical energy.
