NMS06 was disconnected from power, dismantled and placed in storage in November 2008 due to runway expansion.

  7. DNL: 1st Qtr, 2011 vs. 1st Qtr, 2010 65 DNL federal noise compatibility threshold of significance Due to malfunctions at NMS09 in Feb and Mar, the 1st Qtr, 2011 DNL at that site was estimated from daily Jan DNLs and runway use patterns for the remainder of the quarter.

  8. Five Qtr DNL Comparison 65 DNL federal noise compatibility threshold of significance NMS09 data was available Jan 2-24, but not most of Feb, nor any of Mar. DNL at NMS09 was estimated over all days from daily operations per runway, especially those by louder hush-kitted aircraft. These numbers were used to calculate the DNL at NMS09 for this quarter as a whole. This quarter, data was available every day at the remaining nine sites.

  9. Distribution of Noise Events

  10. Top 3 Lmaxs at each NMS, 1st Qtr,(1 of 2) Sound Exposure Level is a measure that takes into account all noise over the entire duration of an event.

  11. Top 3 Lmaxs at each NMS, 1st Qtr,(2 of 2) Sound Exposure Level is a measure that takes into account all noise over the entire duration of an event.
