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

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...

Effects of sonic booms on breeding gray seals and harbor seals on Sable Island, Canada.

The Concorde produces audible sonic booms as it passes 15 km north of Sable Island, Nova Scotia, where gray and harbor seals occur year round. The purpose of this research was to assess how sonic booms affect these seals. The intensity of the booms was measured and three types of data (beach counts, frequency of behavior, and heart rate) were collected before and after booms during the breeding...

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...

Sound Propagation of Sonic Booms through Real Atmospheres Emitted from a New Supersonic Business Aircraft

Supersonic air transport generates sonic booms that can affect people, animals and structures. There is a renewed interest in high-speed transport for civilian application. The widely used standard atmosphere for sonic boom prediction is neither capable of describing topographical variation, nor temporal variations, nor the impact of wind on the propagation of a sonic boom. However, within the ...
