Supersonic flight over land is
currently restricted in the U.S. and many countries because sonic
boom noise disturbs people on the ground and can potentially damage
private property. NASA has developed a method for generating low
level sonic boom noise similar to that anticipated for quiet
supersonic flight. As sufficient research is assembled, there is
potential for a change in federal and international policy. The
Waveforms Sonic Boom Perception and Response Risk Reduction
(WSPRRR) test will utilize a specialized maneuver developed by NASA
using an existing F-18 research aircraft to correlate human
annoyance response with low level sonic boom noise in a community
setting. This effort is designed to evaluate remote aircraft basing
and operations, community engagement, sonic boom measurements, and
community annoyance surveys. The effort will improve research
methods for future community-scale response testing using a
purpose-built, low boom flight demonstration aircraft (LBFD). NASA
supported two prior risk reduction field tests to evaluate data
collection methods for low boom community response at Edwards Air
Force Base (EAFB) in November 2011(see ref. 1&2). The findings
from both studies are not readily generalizable to a larger
population, as the residents at EAFB are accustomed to hearing full
level sonic booms on a routine basis.
This is a new information
collection. Surveys A and B test contrasting survey methods. The
surveys are being executed in parallel because they have different
research goals. Results of Survey B do not depend at all on results
from Survey A. Clearance for Survey A exists (2700-0166). There
were no terms in 2700-0166 that made clearance for Survey B
contingent on results from Survey A
