18 Introduction to Aircraft Noise Modeling Noise modeling must comply with FAR Part 150 requirements: Use the current FAA-approved Integrated Noise Model (INM) Version 7.0 Use annual-average day aircraft operations Use aircraft types from the INM s database Use FAA-approved aircraft substitutions Use the Day-Night Average Sound Level (DNL) metric to assess impact

19 Introduction to Aircraft Noise Modeling Noise modeling must comply with FAR Part 150 requirements: May not alter standard INM departure and arrival profiles without FAA s approval May not create aircraft substitutions without t FAA approval May not use noise measurements to modify the INM aircraft noise database

20 Introduction to Aircraft Noise Modeling

21 Introduction to Aircraft Noise Modeling Background on the INM FAA s preferred aircraft noise model for 30 years Required for FAR Part 150/161 Studies and NEPA documentation (i.e., EAs and EISs) FAA continually updates the INM and regularly releases new versions of the model Updates reflect improve speed of computers, revised or new acoustic computation algorithms, the addition of new aircraft types

22 Introduction to Aircraft Noise Modeling Aircraft Noise Modeling Concepts The loudest aircraft events often govern the noise exposure at an airport Each nighttime (10 pm to 6:59 am) event is equal to 10 daytime (7 am to 9:59 pm) events Assuming all else stays the same (i.e., fleet mix, day/night split, runway use, flight track use): a doubling of operations results in a 3-dB increase in the DNL a halving of operations results in a 3-dB decrease in the DNL

23 Introduction to Aircraft Noise Modeling Aircraft Noise Modeling Concepts The aircraft types, number of annual-average day operations, and nighttime weighting determine the amount of noise exposure The runway locations, runway use, flight track locations, and flight track use determine the distribution of the noise exposure
