What are field noise measurements?
The Part 150 Study Update will include an extensive field noise monitoring/ noise measurement program. Approximately 40 sites around the airport have been selected for inclusion in the noise measurement program which will consist of two separate noise measurement sessions. Larson Davis Model 700, 720, and 820 sound level meters will be set up at the selected locations to collect 10 days of continuous noise level data. Single event noise measurements will also be conducted at selected locations. Field noise measurements are conducted to allow the calibration of the Integrated Noise Model (INM) to conditions that exist at a particular Airport. The project team is conducting two separate noise measurement sessions to gain a greater understanding of the effects that different airport operating and weather conditions play in the dissemination of noise in the vicinity of Dayton International Airport.
