DORA Report 9023: The Use of Leq as an Aircraft Noise Index

We would like to hear from you

The CAA is committed to improving how we deliver services, help us by completing a short survey about your experiences today

The results of the public consultation on the proposal to replace the Noise and Number Index by Equivalent Continuous Sound Level are reviewed. Although there were many questions about the way in which Leq might be used, especially with regard to the distinction between day and night, there was general support for its adoption. Means for calculating Leq contours are discussed, as is the comparability of NNI and Leq values.
