11.   An engineering study is under way to determine if the fence helps reduce noise.

12.   At most airports, reducing noise in one area usually means shifting it to another neighborhood.

13.   All three offer ABS, and a plethora of structural improvements to further reduce noise and improve ride and handling.

14.   Environmentalists have called for reducing air-tour flights over Grand Canyon to reduce noise and to provide hikers and rafters with as much natural quiet as possible.

15.   Engineers have stiffened its structure, added sound-deadening materials and installed double door seals to reduce noise.

16.   Even the dinnerware was bolted down, Miss Sorel recalled, to reduce noise that might be picked up by the prowling submarine fleet.

17.   Finally, the Neon gets full-framed doors that increase body stiffness, improve window fit and reduce wind noise.

18.   Hamilton and James Adams Jr. have patented an algorithm for reducing this noise in the green tones of a digitized image.

19.   Hatfield said the FAA still believed that the experimental routes would reduce noise because they pass over industrial areas, not residential ones.

20.   He says noise is reduced by using only one blower on a piece of property at a time and using it at half-speed rather than full throttle.
