Research 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...

Subjective Response to Simulated Sonic Booms with Ground Reflections

The Sonic Boom Simulator at NASA Langley Research Center was used to (1) quantify subjective loudness of simulated composite sonic booms, each of which was comprised of a simulated direct (non-reflected) boom combined with a simulated reflection of the direct boom, and (2) evaluate several metrics as estimators of loudness for these composite booms. The direct booms consisted of selected N-wave...

Simulated Sonic Booms and Sleep : Effects of Repeated Booms of 1 . 0 Psf

Eight male subjects in each of three age groups (21-26, 40-45, 60-72 years) slept in pairs in the CAMI sonic boom simulation facility for 21 consecutive nights. The first five nights were used to acclimate the subjects (nights 1 and 2) and to obtain Baseline data (nights 3-5); the 12 subsequent nights (Boom) involved the hourly presentation of simulated sonic booms at an overpressure level of 1...

Sonic booms and sleep: affect change as a function of age.

This study concerned the measurement of mood changes resulting from simulated sonic booms occurring during sleep. Subjects from three age groups (21 to 26, 40 to 45, and 60 to 72 years old) spent 21 consecutive nights in a sleeping room equipped for sonic-boom simulation. During the sixth through seventeenth nights, simulated sonic booms of 1.0 psf "outdoors'' overpressure level (.1 psf measure...
