Urban Air Mobility Noise Remote Test Response by Geographic Area and Comparison to In-Person Test

This paper discusses results of a remotely administered psychoacoustic test that investigated annoyance to Urban Air Mobility (UAM) vehicle noise. One of the main test results was that test participants residing in areas of low and high noise soundscapes reacted differently to the UAM vehicle noise. Potential reasons for this result are presented via examination of responses to post-test questions. The paper also compares the remote test responses with those from an in-person test that compared conventional lightweight helicopter noise responses to that of noise from a variety of UAM vehicles. A portion of the remote test participant responses produced a span of mean annoyance responses to UAM vehicle noise that was different from that produced by the in-person test participants. Post-test responses are also examined to provide potential reasons for this difference.
