Recomme commendation dation to ide dentify ntify potential ential noise se impacts acts • Consultant’s final recommendation was to use INM Model instead of installing new monitors. Answers to questions: • The FAA used DNL metric (federal std.), our model will use CNEL metric (CA std.) + closer grid spacing compared to FAA’s 0.5 NM NMT • INM is not affected by urban noise; INM data sample size larger than NMT data after removal of samples contaminated by urban noise.
