IGF::OT::IGF "RISK REDUCTION FOR FUTURE COMMUNITY RESPONSE TESTING WITH A LOW-BOOM FLIGHT DEMONSTRATION VEHICLE." THE CONTRACT SHALL CONSIST OF TWO PHASES. THE FIRST PHASE SHALL ADDRESS THE CREATION OF A CONCEPTUAL PLAN FOR COMMUNITY RESPONSE TESTING USING AN EXPERIMENTAL LOW-BOOM AIRCRAFT, AND THE IDENTIFICATION OF RISK AND DEVELOPMENT AREAS ASSOCIATED WITH THE PLANNING, EXECUTION, AND DATA ANALYSES OF SUCH TESTING. THE SECOND PHASE SHALL ADDRESS THE HIGH PRIORITY RISK AREAS THROUGH ADDITIONAL RESEARCH OR EXPERIMENTATION.THE CONCEPTUAL TEST PLAN SHALL ADDRESS A BROAD SCOPE OF TEST ELEMENTS. THE ELEMENTS THAT SHALL BE CONSIDERED AND ASSESSED INCLUDE, BUT ARE NOT LIMITED TO:LESSONS LEARNED FROM A PREVIOUS NASA PILOT COMMUNITY STUDY CONDUCTED IN 2011 AT EDWARDS AIR FORCE BASE, AS DOCUMENTED IN:J. PAGE ET AL., WAVEFORMS AND SONIC BOOM PERCEPTION AND RESPONSE (WSPR): LOW-BOOM COMMUNITY RESPONSE PROGRAM PILOT TEST DESIGN, EXECUTION, AND ANALYSIS, NASA CR-2014-218180.S. FIDELL ET AL., PILOT TEST OF A NOVEL METHOD FOR ASSESSING COMMUNITY RESPONSE TO LOW-AMPLITUDE SONIC BOOMS, NASA CR-2012-217767.SELECTION OF COMMUNITIES TO PARTICIPATE IN THE FUTURE STUDIES (E.G. NUMBER OF COMMUNITIES AND THE CRITERIA AND METHODOLOGY FOR THEIR SELECTION)STRATEGIES TO INTRODUCE A NEW NOISE SOURCE TO A COMMUNITY AIMED AT ELICITING COOPERATION AND MINIMIZING BIAS IN ACQUIRED DATA SELECTION OF STUDY PARTICIPANTS WITHIN THE COMMUNITIES (E.G. NUMBER OF PARTICIPANTS AND METHOD/CRITERIA FOR THEIR SELECTION) ANNOYANCE DATA REQUIRED AND ACQUISITION METHODS ACOUSTICAL DATA REQUIRED AND PREDICTION/ACQUISITION METHODS ANALYSIS METHODS TO OBTAIN USEFUL NOISE-ANNOYANCE DOSE-RESPONSE RELATIONSHIP(S) SONIC BOOM EXPOSURE (SINGLE EVENT LEVELS, NUMBER OF BOOMS PER DAY, TIME OF DAY) APPROACHES FOR IMPROVING TEST EFFICIENCY AND AFFORDABILITY COST, TIMING, AND TEST DURATION CAPABILITIES AND PERFORMANCE OF THE LOW-BOOM RESEARCH AIRCRAFT AND ITS IMPACT ON TEST EXECUTION
