747-8 Engine Noise Testing
in 2006 Boeing Company and General Electric successfully completed airplane engine ground testing on noise-reduction improvements being incorporated into the new 747-8. The three-week ground test on a GE90-115B engine conducted at GE's test facility in Peebles, Ohio, focused on noise-reduction technologies planned for incorporation into the engine case and nacelle of GE's GEnx-2B, which will power the 747-8. An elaborate array of monitoring equipment and microphones recorded engine operating conditions and noise levels at multiple locations in and around the engine. The test results, combined with other noise-reduction technology applied to the 747-8, show projected reduction in noise levels on the order of 10 decibels (dB) relative to the 747-400. This noise reduction puts the 747-8 10 dB below International Civil Aviation Organization (ICAO) Chapter 4 standards.
