COMPUTER ALGORITHMS FOR ALCOHOL DISORDERS IN THE ELDERLY

Not Available During Rocket launch significant noise can be generated and propagated to the surrounding environment that can be disrupting to both communities and wildlife. Assessment of these impacts requires knowledge of the acoustic source mechanisms, propagation effects, and requirements under the National Environmental Policy Act. In Phase I we will draw heavily on the rocket engine acoustic source investigative testing that we recently completed as well as expand our recent literature search on rocket engine acoustic sources. Our far field acoustic propagation techniques, developed from explosive charge detonation and large calibre gun firing tests, will be combined with our knowledge of rocket (engine noise and vehicle bow shock) sources to form a preliminary far field noise footprint prediction method. It is anticipated the results would be shown grahically using Air Force developed software, NMPLOT. Also, we intend to add IBON to our current noise ciriteria data base. In Phase II the nosie footprint software will be formalized, tested with field measurements and a graphical user interface will be added to complete the nosie assessment tool.
