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.),
• ur model will use CNEL metric (CA std.)

+ closer grid spacing compared to FAA’s 0.5 NM

• INM is not affected by urban noise;

INM data sample size larger than NMT data after removal of samples contaminated by urban noise.
