Recent progress on sonic boom research at NASA
Sonic boom research conducted at NASA through the Supersonics Project of the Fundamental Aeronautics Program is oriented toward understanding the potential impact of sonic boom noise on communities from new low-boom supersonic aircraft designs. Encompassing research in atmospheric propagation, structural response, and human response, NASA research contributes to knowledge in key areas needed to...
متن کاملResearch On Subjective Response To Simulated Sonic Booms At NASA Langley Research Center
Over the past 15 years, NASA Langley Research Center has conducted many tests investigating subjective response to simulated sonic booms. Most tests have used the Sonic Boom Booth, an airtight concrete booth fitted with loudspeakers that play synthesized sonic booms pre-processed to compensate for the response of the booth/loudspeaker system. Tests using the Booth have included investigations o...
متن کاملComments on Sonic Cannons
Three types of sonic cannons: Sonic cannons have had three incarnations over the years. The first implementation uses very low frequency sounds (essentially in the octave below the lower note on a piano keyboard) that have a significant vibro-tactile, or " whole body " response. This has been well studied in the literature and can result in nausea, a feeling of fullness in the chest and even he...
متن کاملHuman Response to Sonic Booms-recent Nasa Research
1042 interviews were merged with the noise data in order to plot the reactions in each community against noise level. Figure 5 shows that at, for example, about DNL 25 to 35 dB(A), about 30 percent of the respondents said they were "very much" annoyed by sonic booms. These results can be directly compared with a 1985 survey of residents around five airports in the United Kingdom. Figure 5 indic...
