At approximately 6:45, the members of the metrics committee joined the Monitoring Committee, at which, Bill Willkie of Leigh Fisher Associates described the noise monitoring process to take place in and around the Louisville metro area.
The following information was presented at the Noise Monitoring meeting of the same date. The LFA team discussed their proposal to address the issue of 1/3 octave band measurement. This is one of the community-selected "alternate metrics." See previous Noise Metrics meeting notes for details on the scenarios discussed to measure 1/3 ob.
Bill Willkie detailed their discussion for this. He proposed two monitoring sites for 1/3 obm. One would be to the North, along the East runway centerline, where there is currently, in his words, a cluster of 3 sites. This cluster is a combination of LFA and community-selected sites. Mary Rose recommended that the site be on Eastern Parkway.
Bill W. suggested another site to the South, in the Minor Lane Heights area. He elaborated on this type of measurement, describing it as taking a "finger-point" of the aircraft's noise. He said it provides data not just about that particular point of the aircraft's travel, but a "profile of the noise." This requires that an operator visually identify the aircraft as it goes over, and match this information with the monitored data.
Bill W. also reminded the group that only will the 1/3 obm data be available, but that all other sites will be reported in C-weighted format.
The sites for LFA were discussed and it was decided by the monitoring committee to pull them out of a hat at random.
