ARTSMAP 2 There was a 23.2% decrease in noise complaints received in the first 9 months of Land Use and Zoning 2 2008 as compared to the same period in 2007 (769 vs. 988 in 2007). The number of households registering at least one complaint increased by 29% (102 vs. 72 in 2007). DEN Noise Hotline Policy 3 Five households registered a combined 45% of total complaints. The percentage of com- plaints received during Nighttime Aircraft Operations (10:00pm to 7:00am) for the first 9 Glossary of Terms 3 months of 2008 was 11.5% of total complaints received.
